XmegaPilot to use MARG AHRS algorithm by Sebastian O.H. Madgwick

Reference Available Below:

An efficient orientation fillter for inertial and inertial/magnetic sensor arrays (Sebastian O.H. Madgwick)

Various algorithms of varying complexity and computational requirements are available to determine the orientation of an object using 9DOF sensors. The Kalman filter was considered and not selected due to issues of simulation, complexity, computational load, and lack of knowledge and experience to take advantage of numerically well… Continue

MTK3329 Size - Compare to Atmel Xplain and an Ardupilot

The MTK3329's arrived and they are amazingly small. The picture shows an Atmel Xplain development board next to a DIYDrones Ardupilot. Below from left to right, is the amazingly small Gmm-U1, the FGPMMOPA6B with integral LNA and 16mm tuned patch antenna followed by a Sarantel helical SL1203A passive antenna. I have an old Rockwell Jupiter GPS module that… Continue
