PolarFinder is an useful tool for helping you in polar alignment of your mount. PolarFinder shows you the actual of the Polaris or the Sigma Octantis using the system time and GPS location. PolarFinder is an astronomical app. Pro version with no ADS.

Scope Companion is software for computing performance parameters of optical equipment for astronomy, primarily designed for telescope novices and first-time buyers of optical systems.

Functions that are typically used in the dark come on red night view screens with adjustable screen brightness.

Upon input of basic specifications, such as aperture and focal length, Scope Companion calculates the ideal performance of the optics and plots a performance graph. Performance data can also be calculated for binoculars.

The imaging section calculates the field of view with a given CCD camera and lens/scope configuration. The data can be visually confirmed by means of a simulation against the surface of the moon and other objects.

Additional helper functions include a star transit counter for measuring the field of view of an unknown eyepiece, a dew point estimator, a compass, north/south polar finder, level meter, observatory clock, red light lamp, etc.

The dew point estimator supports built-in temperature/humidity sensors. The compass compensates for magnetic declination or points magnetic north.

An Observatory Clock in red night view mode with adjustable screen brightness is provided for use during observations. It shows local, universal, sidereal and martian time plus the positions of the Jovian moons!

Rise and set times are computed for the major solar system objects.

Visual aids include a red lamp and a magnifier implemented with the built-in rear camera.

Attention: The database contains only Polish, German, Czech and Slovak transmitters...

This tool will help you find nearest DVB-T channels. It uses GPS and Internet. DVB-T finder shows channel number, frequency, power, polarisation of the signal, azimuth, channel list, elevation chart (work slow) and shows map

In the database there are transmitters from Poland but the database will be updated

The map and elevation chart are hidden in transmitters detail menu.

Finding a TV satellite, in azimuth, can be pretty difficult. Before you can find it with a compass you have to do some calculations using GPS location, magnetic variation, compass azimuth and satellite azimuth.
Satellite Director replaces all of that. See tips to success below !!!

WARNING: The only sensor you need is the compass. Unfortunatly you have to calibrate the compass before using it. Compare your phone's compass with a real compass !!
Metal covers/cases or covers/cases with metal/magnetic closure will influence/disrupt the compass of your phone or tablet. Do not use these covers !! The compass of your phone can also get inaccurate because it is affected by other electro - magnetic fields or because it is weakened by age. Calibrating the compass may not help anymore.
PRECISION DEPENDS ON THE QUALITY OF YOUR PHONES HARDWARE.

Warning: If you use Cyanogenmod / Cymod then you may run into Android compatibility issues and the app may not work. You should then complain to Cyanogenmod / Cymod and not to me.

This app is add-free !
Help me to continue the work on this app and watch some of my videos on Youtube. The advertising in the videos provides some required money (houres of work, phones to test on, satellite equipment, etc.).

How does it work ?
Just enable the GPS in your phone or enter your GPS location, select the desired TV satellite and point your phone to the sky to target (find) the TV satellite. You have found the satellite when the white ball is in the white circle and the cyan ball is in the cyan circle. Align, in azimuth, the offset arm of the satellite dish to the cyan arrow on the phones display and the satellite dish is aligned in azimuth with the satellite.
Selectable audio tone, camera preview, continuous mode (no pause), color pickers or a user defined satellite position may make it easier for you to find the desired TV satellite. The satellite list contains 280 satellites.
Optional you can take a photo (resized)/screenshot by touching on the director tab. The photo/screenshot is ONLY stored on the phones memory card.
Optional: you can get an indication when you are to close to iron (dish/pole) in the form of an green/yellow/red bar.

Satellite positions are derived from Agi's database. Some positions may seem not accurate (example: Hispasat 30°w is at 29.96°w in the satellite list) but they are very accurate.

New phones with Android 4: in case of a wrong compass reading the "Settings" screen has options to correct the compass readings !!!!

Previous versions are available from my website.
If you have any questions, requests or problems PLEASE write an email.

All language translations by Google Translator.

3 tips to success:
1- do NOT go to close to the iron dish, iron lnb arm or iron pole (keep at least 30 cm distance)
2- calibrate the compass of the phone by waving it in a figure 8 before you start
3- optional: calibrate the compass of the phone by rolling your phone along its length axis about 2-3 turns (works on some phones)

SatFinder, an Android satellite finder.

SatFinder is a tool for finding TV satellites and aligning satellite dishes. Use you AR camera view to see and target satellites in the sky.

*New feature: Ability to manually enter Location latitude and longitude details in case Location cannot be automatically determined in case of "no connectivity"

SatFinder uses your phone sensors to detect your physical location and calculates azimuth and elevation needed for your satellite antenna to face.

Augmented Reality View:
Use your camera for Augmented Reality View which paints the satellite icons in places where they're positioned in the sky. It gives a realistic view to the sky and it helps to make sure there is a line of sight (LOS), i.e. no obstacles, such as tree branches or house tops, between the satellite dish and the satellite itself.
- Touch screen to take a screenshot of Augmented Reality view
- Pinch to zoom satellites in and out. Double tap to reset.

Target Satellite View:
Use Target Satellite View to find or to "lock onto" a particular satellite. Direction arrows simply guide you to the desired satellite position.

This is the pay version of SatFinder. This app is optimized for Android 4.0. On older devices it will look a bit different than on the screenshot...

SatFinder (Satellite Finder) is a tool which will help you to set up satellite dish. It will give you azimuth, elevation and LNB tilt for your location (based on GPS) and chosen satellite from list. The result is shown both as numeric data and graphical on google maps. It has also built in compass which will help you to find proper satellite azimuth.

The satellite list is complete and includes all televison satellites, so the app should work worldwide. If you found some errors please send me e-mail. It will help me make this app better ;)

Since version 1.07 there is whole world FTA and encrypted channels database. It take a few seconds to show whole list so be patient. It use internet connection. Top 10 countries got fixed language on nice list. The list will be updated. The users from another countries can type language manual. But the list uses language shortcuts, for example - English = eng, German = ger, etc... The channel list is still incomplete - I'm working on it. If you find error on list please send me e-mail...

Before buying this app: have you tried, can you install, the free version ?
If you cannot install the free version your phone does not have a compass, which is required for the director function.

This app is simular to the free Satellite Director but has
additional features, some may require the use of internet:
- enter street and city to get your location coordinates
- your location coordinates via network and/or GPS
- find the exact location with the help Google Maps
- see in satellite view above your location where to point the dish
- create your own satellite sat-lists with only those satellites in it that you want using the build-in satellite list
- reduce and sort the satellite list without restarting the app
- on-line help pages
- 'simple' mode without balancing the phone
- export/import the satellite lists to SD card (backup)
- overrule the build-in satellite list with your own list
- vibrate
- up to 6 satellites simultaniously displayed
- display for your location and all satellites the values for: azimuth, elevation and skew
- the current location via the network
- update the satellite list from a source (USSTRATCOM-AGI) or website (sats.csv, Enigma satellite.xml, Satellite Calculations)

Warning: metal covers/cases or covers/cases with metal/magnetic closure will influence/disrupt the compass of your phone or tablet. Do not use these covers !!

Finding a TV satellite, in azimuth, can be pretty difficult. Before you can find it with a compass you have to do some
calculations using GPS location, magnetic variation, compass azimuth and satellite azimuth.

Satellite Director replaces all of that.

Just enable the GPS in your phone or enter your GPS location or use the map to find your location,
select the desired TV satellite and point your phone to the sky to target (find) the TV satellite.
Balance your phone. You have found the satellite when the white ball is in the white circle
and the cyan ball is in the cyan circle. Align the offset arm, in azimuth, of the satellite dish to the cyan arrow on
the phones display and the satellite dish is aligned in azimuth with the satellite.

Selectable audio tone, camera preview, continuous mode (no pause), color pickers or a user defined satellite position may make it easier for you to find the desired TV satellite.
The satellite list contains 280 satellites.

New phones with Android 4: remember that the "Settings" screen has options to correct the compass readings, if needed.

This app helps you to align your equatorial telescope mount toward the celestial pole at daytime.
But you know it does not guarantee high­-precision adjustment.
When the white circle is the center of target, the surface of your device is toward the celestial pole.
This app is the modified version of "Celestial Pole".

usage:
Your device is fixed on your equatorial telescope mount and you will set the white circle on the center of target.

The right snapshot is the example of an error that it would not get the north latitude of your position.
This app may does not work in the Southern hemisphere.

Telescope Flashlight is a handy red astronomy flashlight for the amateur astronomer and telescope user for Android.

As every amateur astronomer knows, red light preserves dark-adapted night vision better than white light. To help you read star charts, operate your telescope and simply walking around that star party you’ll need a handy red light to find your way. Use when your main red flashlight isn’t handy—or runs out of battery.

Simply turn on the flashlight when dark-adapted conditions are required. NOTE: The screen itself is used as the flashlight, the color of the hardware LEDs cannot be changed unfortunately!

Please email or visit my website for feedback, bug reports, and new feature ideas.

Don’t waste any more time with annoying satellite dish alignment.

The Sat Aligner App guides you automatically through every single step and tells you what to do.

First of all, select the satellite (e.g. Astra 19.2°) to which you would like to adjust the sat dish.

In the second step, you have a choice between the normal oval form or the ever more common flat antennas.

If you decide on the oval offset dish, you just need to input the offset angle or the length and width of the dish. Now the app has all the data to adjust your sat system correctly. All the necessary angles can now be calculated automatically.

In the next-to-last step, the horizontal adjustment of the satellite dish is set with the help of the built-in compass.

In the last step, the vertical angle of the sat antenna is quickly adjusted with the built-in clinometer and you’re already done!

Use your phone's camera to quickly and easily determine where commonly used satellites appear in the sky. An Augmented Reality app that DirecTV and Dish Network Installers can appreciate. Hold the phone in landscape mode, launch the app, and it will draw the location of every known geostationary satellite on the screen allowing you to quickly identify any potential line of sight issues. Using the camera button will allow you to capture the current screen contents to the SD card, for documentation or to show the customer. For a phone without a camera button, simply tapping the screen or the search button will also capture the screen contents. Bringing the cross-hairs close to a satellite marker will show the computed look angles at the bottom of the screen. Hassle free money back guarantee. If you have a problem, email me, you will find that we are very responsive. Perfect for RV'ers, or Professional Installers.

Works with all geostationary satellites
Select satellites from a list
Azimuth, elevation and skew calculations
Screen capture, saves screen image to SD card

Notes: You must hold the phone in landscape mode (sideways) and make sure the phone pitch is 0, otherwise it can throw off the azimuth and elevation. Azimuth is above the cross hairs, elevation to the left, and roll is lower right. Also, if you have a problem, email me. Developers do not look at the comments and it is not a good method of reaching us.

The latest version asks for permission to access the internet only so that exception reports can be sent, to help us fix any unknown issues with the app.

NOTE: Some users have noticed a problem after upgrading to Gingerbread (2.3.3). Gingerbread has a compass bug, causing issues with apps that use the compass/accelerometer. Google "Gingerbread compass" for more information.

Find and sort astronomical (NGC/IC) objects in seconds with ease.

NGC Mate is a simple database application which contains the full revised New General and Index Catalog of astronomical objects. Its main power is the search and sort capability with which it lets you find the objects you want to observe. You can make your night's observing list in seconds with ease. It contains links to the Messier, Caldwell and Herschel 400 objects as well. As a vivid astronomer you can spend more time beside you telescope and let the search be done by NGC Mate.

In the details page you will get information about:

• catalog (including Messier, Caldwell and Herschel 400 object numbers)
• common name
• type and subtype
• constellation
• RA, Dec
• visual magnitude
• size and position angle
• visibility, and transit time

The application can also download images of objects (basically areas around coordinates) from the Internet, if you have network access. All downloaded images are stored locally in the device's memory, so a second download or network access is not required, until you wipe the cached images from the memory.

Please have a look at our video tutorial to see how easy it is to operate the application.

This free utility lets you search in the Maritime Identification Digit (MID) database by country or by MID number. The utility comes very handy when you see a ship's Maritime Mobile Service Identity (MMSI) number on the AIS and you want to know which country the given vessel is coming from. Or, you want to know the MMSI part of the AIS for a given country.

Under the first tab you can search for a county, based on its MID number. You can do it by scrolling the list or searching for it by entering numbers. Scrolling is done by swiping the screen up or down. As the list is scrolled a number column appears on the right side of the list. If you tap on it and hold it, you can move your finger up and down to quickly jump to the number under your finger.

The second method is to enter digits into the search field and let the application reduce the list to only those countries for which the MID starts with the entered number. As you type into the text field the application searches the database and displays all countries which has an MID starting with the numbers you have entered. If there are no countries for the typed in numbers the list will be empty. As soon as you tap on a list item the MID will be put into the search field and this single item will be shown.

Any time you can change to the other representation of the database and start searching for a MID number by country. To do so, tap on the "By country" tab. The list and the search field on this screen behaves the same way as described above. The only difference that in this list you search for a MID number by a known country.

If you have a WiFi bridge on your boat or sailing ship, this utility will be your best friend very soon. It connects your WiFi capable phone to the bridge and listens for standard NMEA sentences of the following types:

• GPS positions,
• waypoints,
• wind direction and speed,
• course and speed over ground,
• depth,
• water and air temperatures.

It then displays the readouts of the above mentioned devices. By tapping the unit field you can change the currently used unit. Tapping the screen toggles the day-time (white on black) and night-time (red on black) views. With the long-tap over a given gauge line the context menu appears where you can reset the value (and the stored min/max) of the gauge or bring up the settings dialog. In the dialog you can set parameters for announcing the readout or set alarm values.

This is of great help for example when you are anchoring and have to look after a lot of things and you still want to have a continuous readout of the depth gauge. In this case you can setup an announcement for a time interval or depth change. You can also set an alarm for any gauge for any value. Your phone will alert you e.g. when the wind speed grows above a certain value or when your vessel reaches a pre-defined speed over ground.

Understanding and constructing maritime flag signals can be crucial in situations when all your electronics fails or you or the signaling station have language problems. This application contains the full International Code of Signals database and knows the proper signaling technique, including the usage of substitute and code flags. It has two main functions:

• interpret flag signals or
• show which flags should be hoisted for a given message.

In interpretation mode, flags are entered by selecting them from a list of flags on the right hand side of the screen. Selected flags are then inserted into the list of hoisted flags in the middle of the screen. This list can be edited, new elements can be inserted or existing ones can be removed from it. As you enter the flags a rough syntactical analysis runs on them and formal problems are reported.

When a message contains numerous additional information (e.g. coordinates, numbers, names of places) the complete message is sent in chunks, so called hoists. At the end of each hoist you have to check the completeness of the chunk. At the end, the whole message can be interpreted with all its additional information.

In send mode you can view and search the generic and medical part of the complete ICS in two independent lists. Both lists are structured the same way as the original ICS book, you can open/close chapters, sections, scroll them and read each message. The most powerful part is that you can search both lists for any term. After the search, only those messages (and their section and chapter descriptors) remain in the list which were matching the search criteria. Tapping on a message element will select it for sending. After entering values for additional information you can let the application generate the flags in chunks of hoists.

The usage of the application is very easy and self-intuitive. The search is very robust and works as a full-text search, hunting for matches in any part of the ICS database.

Currently only the English ICS is supported. If you find any mistakes in the database or want your localized version included, please pick up contact with the author.

As a sailor you know how essential it is to regularly check the position of your ship during the voyage. Any coastal feature that can be seen by the navigator, can be used for this purpose. The Cross Bearing Fix is probably the most common for position finding. To achieve it, bearing sights on at least 2-3 fixed objects should be taken over the widest arc and over the shortest period of time.

Normally you use a compass to take the bearings, but nowadays's gadgets, just like your mobile phone can also be used for this purpose as it contains a magnetometer. This utility allows you to take as many bearing as you wish by sighting the coastal feature with the built-in camera and taking a picture of it. Along with the picture the magnetic bearing and the time stamp is saved for later reference when you are doing your chart-work.

Features include:

• List of bearings with time stamp and picture
• Continuous camera view for coastal feature identification
• Continuous read-out of magnetic bearing, roll and pitch for correct camera handling
• Automatic zoom-in for better coastal feature identification
• Calibration, in case of local magnetic interference

A mariner should know all recommendations of the IALA lighting and buoyage system. Have you ever had problems identifying lighthouse beams at night or imagining how an abbreviation used on maps would look like in real life? If yes, this utility is what you need.

The utility has two major working modes. In one you set the parameters of the light source and the application tells you the corresponding abbreviation. In the other mode you can enter the abbreviation from the navigational chart and the application shows you how it would look like at night.

Selectable characteristics include:

• Fixed
• Occulting
• Group occulting
• Composite group occulting
• Isophase
• Flashing
• Group flashing
• Composite group flashing
• Long flashing
• Quick, very quick, ultra quick
• Group quick, group very quick
• Group quick + long, group very quick + long
• Interrupted quick, interrupted very quick, interrupted ultra quick
• Morse
• Fix + flashing
• Alternating

Screen controls for selecting the number of flashes in groups, composite groups or the characters for a Morse code are enabled or disabled depending on the selected phase characteristic.

When the selected light phase belongs to a cardinal or lateral buoy then the light-house tower is replaced by the corresponding cardinal or lateral buoy on the drawing.

When entering an abbreviation from the chart the height of the light-house or the range of visibility are optional and may be omitted.

Please make sure you check out our short screen-cast presentation for a quick introduction.

As a sailor you know that radio traffic - mainly in emergency - is very important and has to comply to a strict form to make messages compact, yet understandable. This ensures that the most information is transferred to coastal radio stations with the least time and effort. This application helps mariners or their co-boaters to compose various standardized VHF messages, including distress, MOB etc. based on user input. After supplying the necessary information the application generates the corresponding text to be transmitted to CRS.

Features include:

• Composing of distress, MOB, distress relay, distress ACK, urgency, safety and cancel alert messages
• Use of built-in GPS
• Save name of ship, call sign, MMSI and name of skipper in preferences for auto-fill
• Text to speech, to help those who have problems speaking out a written English text. Please make sure that your TTS service is set up correctly in order to pronounce English text.
