MGL Avionics SP-4 Attitude (horizon) sensor
The SP-4 contains 3 MEMS gyros and 3 MEMS vibrating body accelerometers. Using a 16 bit data acquisition subsystem, a powerful ARM7 32 bit processor is used to provide stabilized attitude information. Together with an SP-2 magnetometer on the same Airtalk communications link, the gyro heading can be automatically slaved to the magnetic heading.
