Due the progress in sensor electronics it was possible to design a autopilot with one planar PCB. Compared to the HB-Autopilot V1.0 the following differences are given: • use of new planar sensors: magnetsesor HMC5743, rate sensors LPR530AL LY530ALH or IDG500, IXZ500 • only one free 16Bit ADC input, and free 8 ADC Inputs with 10 bit, no intern difference pressure sensor, the 16Bit ADC is optional. • dimensions 57mm*30mm* 11mm, cost: 26Euro for the 4 layer pcb, and 170 to 180 with all sensors. For normal plane aircrafts you can save about 60 Euro (no magnetsensor, no 16 Bit ADC, no pressure sensor) This work was done by Benjamin Forke. You can get his bachelor thesis wirtten in German, if you wrote a question mail to paparazzi-devel at nongnu.org. The software implementation of the Paparazzi code for normal plane and quadrocopter is currently in work.
