In current mobile technology, we use accelerometer, compass and GPS in latest mobile models. Here some innovative test cases and expected results of those components, when we test in some places like in the space, on any other planet, satellite, center of gravity of earth and center of magnetic field of earth. Those cases are discussed as following:
1. In space: In space, accelerometer, compass and GPS will not work. because accelerometer and compass have required gravity and magnetic field respectively. But when we use accelerometer and compass nearer any planet, then we get relative values as that planet’s field with some accuracy. and GPS will not work, if we are close to any other planet excluding earth. Because for GPS usage, we require human invented working satellites.
2. On any other planet (excluding earth): Still GPS will not work in any other planet. and we get relative values of accelerometer and compass as that planet.
3. On center of gravity of earth: We cannot predict results for accelerometer and GPS. It is possible that we get garbage values for accelerometer. and compass will work proper because location of center of gravity and location of center of magnetic field of earth are different.
4. On center of magnetic field of earth: In this case, we get garbage values for compass and get proper values for accelerometer and GPS. But still It is possible that if there is any relationship between gravity and magnetic field, then we get unknown results for accelerometer.
For all those cases, I expect results based on physics theories, but still we cannot guess exact results. Those all will work on so many parameters, planet atmosphere and other theories.
