This utility helps you solve this problem by graphically showing you the current position of the Polaris. The application tracks and draws the position of the Polaris (or Octant) in real-time and also displays its hour-angle, the local sideral time, current local time and the longitude of the place. The longitude can be entered manually or obtained using the built-in GPS. The view on the display can be mirrored to match the view in your polar finder scope. Key features are as follows:
• Northern, southern hemispheres
• Naked eye, telescopic view
• Customizable marker angle
• Support for: Astro-Physics, AstroTrac, Ioptron, Losmandy, Skywatcher, StarAdventure, Takahashi and Vixen eyepiece reticles
• Night vision mode
• Enter longitude of your place manually or via built-in GPS
Note: On some new devices running Android 4.x the preferences menu can be reached via pressing and holding the Recent Apps Button - which is a ‘soft key’ (not the Home button). On Galaxy Tabs there are three buttons at the bottom. The middle one is the main, hardware button. The task manager is just on its left side. Press and hold for about two whole seconds on it, and then the menu comes up.
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
• 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.
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.
• GPS positions,
• wind direction and speed,
• course and speed over ground,
• 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.
• 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.
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.
• 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
• 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.
