Minutes

• @Brian Kilberg

  • both IMU and lighthouse working together

  • need to fix attitude estimation, by ignoring gravity

    • using Mdgwick and MUKF (Multiplicatif Unscented Kalman Filter)

  • had to play with the programming configuration, “set 3rd number to 4“ (should be the length of the short pulse)

  • had to tune the “loop delay“ to have the system run for >1min

• @Titan Yuan

  • BLE TX Cal by tracking 15.4 RX Freq

  • WIP on merging BLE code (https://github.com/PisterLab/scum-test-code/pull/17 )

  • working on paper on temperature calibration

  • delta f between BLE TX and 15.4 RX is approx the same

  • issue with not receiving packets from OpenMote

  • @Kristofer PISTER on 15.4 RX, you can look at IF, this allows you to see your frequency error directly
