Hi Guys,

Please let me know who needs this and any comments.

I'm developing GPS/INS device which is currently developed for my personal quadcopter. Which outputs Position,Velocity,orientation(roll,pitch,yaw or as quternion),Orientation rate as filtered outputs.

I'm using industrial grade IMU(very low noise) and High update rate GPS as measurement units. STM32 micro-controller runs aerospace grade Kalman filter for fusing IMU and GPS sensor measurements.

Note :

1) IMU is factory-calibrated for sensitivity, bias, and axial alignment at 25C. Which works correctly on 15C-35C temparature.

2) -40C to 85C tempatture calibrated device costs additional 300USD.
