Displays heading, roll, and pitch in real-time, using a gyroscope to stabilize the results of one is available.
Based on sample code shown in Professional Android 2 Application Development.
If you do have a gyroscope, be aware that the quality of the drift compensations on the gyroscope sensor vary considerably among devices. In the case that your device has a gyroscope that doesn't work well, there is the option to fuse the gyroscope with the acceleration and magnetic sensors. This option, which uses a fusion of the acceleration, magnetic and gyroscope sensors via complementary filter to determine the rotation of the device, is far more reliable that the gyroscope sensor alone.
Gyroscopes measure the rotation of a device with a pair of vibrating arms that take advantage of what is known as the Coriolis effect, which is caused by the Earth's rotation. By measuring changes in the direction of the vibrating arms caused by a rotation and the Coriolis effect, an estimation of the rotation can be produced. The gyroscope is one of three sensors that are always hardware based (the other two are the magnetic and the acceleration sensors) on Android devices. In conjunction with the acceleration sensor, the gyroscope can be used to create other sensors like gravity, linear acceleration or rotation sensors.
If your device is equipped with Android 4.4 or higher, you *might* have the uncalibrated version of the gyroscope so you can see how drift affects the gyroscope sensor relative to the calibrated gyroscope.

Sensor Kinetics is an advanced viewer and monitor for all of the standard sensors available in your Android device. You can finally see and log the accelerometer, gyroscope or the magnetometer in real time action!
Written by one of the pioneers of the use of accelerometers and gyroscopes within the modern smartphone, it provides a comprehensive look at the total dynamics of the combined operations of all the sensors.
The app demonstrates the use of the accelerometer, gyroscope and the rotation sensor to control a tilt based view navigation like the RotoView technology by INNOVENTIONS. It also demonstrates the operation of the magnetic sensor, the linear acceleration sensor and the gravity sensor within special graphical displays.
Use Sensor Kinetics to monitor and understand the behavior of the sensors while you change the delay setting or activate/deactivate specific sensors. Each sensor is attached to a sophisticated chart viewer. If you need to save or share sensor charts, please purchase the companion Sensor Kinetics Pro.
For educational users, the app includes comprehensive help files which provide physics students with hands-on knowledge of how these sensors interact with smartphones and suggest numerous experiments you can perform on your phone or tablet.
Who Should Use Sensor Kinetics?
Developers, students, hobbyists, technicians, engineers... anyone who's curious about what lies "under the hood" of their mobile device!
Test your Android phone or tablet: Sensor Kinetics allows you to test all of the sensors on your device. For example, you can quickly determine if your Android device has a gyroscope sensor and how fast it's operating. The numerous chart viewers allow you to measure any sensor over time and gauge their accuracy and behavior.
Educational: Sensor Kinetics demonstrates the physics of gravity, acceleration, rotation, magnetism and more as these forces are measured by your phone or tablet. The app includes comprehensive help files with easy to understand information and experiments you can perform with the sensors.
App Developers: View in detail the behavior of the sensors used in your apps. Compare the performance of advanced sensors like gyroscope, linear acceleration sensor and the rotation sensor.

If your device is equipped with Android 4.3 or higher, you even get the uncalibrated version of the gyroscope so you can see how drift affects the gyroscope sensor relative to the calibrated gyroscope.
What would you want to measure rotation angle of? Lots of freaking amazing stuff.
For example, you can measure the rotation angle of (not recommended):
• Your house to prove to the contractor is really is titled
• Your car driving around a corner on two wheels
• Your mountain bike going up a hill faster than your buddies
• Your angle on the ski slope no one else would take with you
• Your plane diving towards the ground
• Your picture frame that just won't get level
• Your R/C truck flying through the air
• Your rockets for your science fair project
Totally impress your friends with all these cool features!
Yup, you can make your phone at least 10 times more amazing (rough estimate) by downloading Fused Gyroscope Explorer and then measuring the linear acceleration of you doing something super sweet.
The linear acceleration of an object is calculated as the acceleration of the device minus the force of the earth's gravitational field ( the tilt of the device). Gyro Linear Acceleration uses a complimentary filter to fuse the acceleration sensor and gyroscope sensor together to provide a measurement of the devices linear acceleration. The acceleration sensor alone is not capable of distinguishing true linear acceleration from tilt, or gravity. The gyroscope sensor is used to find the tilt of the device. The tilt angle of the device can then be used to calculate the gravity component of the acceleration that can then be subtracted from the acceleration to find the linear acceleration.
Most people will find that the end-result of this implementation is that, while linear acceleration can be measured while the device is static (not accelerating), linear acceleration cannot be accurately measured while the device is actually under linear acceleration. This is because the complementary filter, which is used to compensate for the drift of the gyroscope, begins to assume the acceleration of the device is actually tilt, skewing the rotation measurements from the gyroscope.
Related to the linear acceleration problem is that the gyroscope sensor can easily drift out of rotation with the device when it is experiencing vibrations or rapid rotations, even with the help of an acceleration sensor. If you modify the complementary filter to quickly compensate for gyroscope drift with the acceleration sensor, you increase the problem of the complimentary filter confusing linear acceleration for tilt when the device is actually accelerating.
Gyro Linear Acceleration may work well for determining linear acceleration for a static device, for instance, that moves a character or vehicle in a game by tilting the device. Gyro Linear Acceleration will not work well for determining the linear acceleration of a vehicle or other object that actually accelerates the device.
Gyro Linear Acceleration will plot the output of the sensor fusion in real-time and will also log the data to an external .CSV file that can be viewed at a later time on any spreadsheet application.
• Plot data in real-time
• Analog gauges to visualize the outputs
• Log the output to an external .CSV file

This enables pilots to place a secondary Android device with built in GPS receiver in the optimal location for satellite reception (for example, beneath the windshield with an unobstructed view of the sky). That device's GPS data is then sent via Bluetooth by this AddOn app, to one or more other Android devices running Avare (such as a tablet or phone attached to the aircraft control yoke, panel, or pilot's kneeboard).
Put your old Android phones to good use, and add redundancy to GPS navigation. This will convert your second device into a Bluetooth GPS, so it can be placed in an appropriate location in the aircraft, for optimum GPS signal reception. Your primary navigation & EFB phone/tablet device(s) running Avare can then be placed for optimum visibility and physical access; while getting GPS location data from your secondary device running this Bluetooth GPS For Avare app.
- Install Avare
- Install the Avare External I/O Plugin app
Secondary Device (for GPS):
- Install this Bluetooth GPS For Avare app
1. On Secondary Device, launch this Bluetooth GPS For Avare app.
2. On Primary Device(s), launch the Avare External I/O Plugin app, and then the Avare app.
3. On Secondary Device, click the Enable Pairing button from this Bluetooth GPS For Avare app.
4. On Primary Device(s), Pair with Secondary Device using that device's Bluetooth settings.
5. On Primary Device(s), launch the Avare External I/O Plugin app, and connect to Secondary Device using the External Bluetooth GPS menu.
6. On Primary Device(s), start Avare and navigate.
While all this may look complex, once the initial setup is done the routine setup and operation is fairly simple and intuitive.
Note that many dedicated external GPS units will perform more accurately and reliably than the GPS receivers built into most Android devices. This can be due to many factors including the fact that the primary purpose of external units is GPS reception; they may receive multiple GPS bands; they may access supplementary WAAS transmissions; and they may have more sensitive receivers with better noise rejection. Even so, the GPS built into most Android devices will perform well when optimally placed, so we hope this app can save you some money while providing an alternate GPS source.
NOTE: Based on manufacturer and carrier implementations, Android devices handle Airplane Mode differently. If you use Avare in Airplane Mode to reduce battery use and the potential for radio frequency interference, the Bluetooth transceiver in your device may or MAY NOT be active. It's possible that if Bluetooth isn't working on your device after you activate Airport Mode, it may work if you simply turn on Bluetooth again while in Airplane Mode. You could also further investigate how your device actually handles airplane mode with a free tool such as Airplane Mode Modifier.
Please share your feedback, questions and/or comments about this app on our Apps4Av Forum. Check the Forum and our Website for the latest developments.
This Avare External I/O Plugin requires the free Avare app, which should be installed first. You can find Avare on the Google Play Store either in the list of our free apps under the "More from developer" section below.
