Flight controller/display project
There haven't been any new projects for a while. Unfortunatelly, I currently spend most of my time with boring work (PC software) so my own propeller projects also don't show much progress. Although it seems irrational to start another new project now as it might eat up even more time I need to keep my motivation up. And the best thing to do that is to do something crazy. So don't ask why, it's just a fun project.
Feature wish list:
- artificial horizon (requires 6DOF accelerometer and 3D compass)
- air speed (requires pitot tube and differential pressure sensor)
- ground speed (requires GPS)
- altitude (GPS with absolute pressure sensor as backup)
- heading (compass + GPS)
- position (GPS)
- ground proximity "radar" (ultrasonic ping sensor)
I know there has been some similar P1 project some years ago. But I think sensor tecnology has improved a lot since then. MEMS accelerometers are far less accurate than the laser gyroscopes used in modern commercial aircrafts. So they are not suitable for a real inertial navigation system but together with a 3D compass they are good enough to provide an artificial horizon.
The first thing to do is to select the best fit of sensors. My memory is bad and the search function of this forum is also... I know that there has been some discussions about different types of sensors, so any pointers are welcome.
