06/19/2024 Spaceport America Cup (RPi Pico)
Pre-releaseThis is the version of the Active Drag System software that flew on the 2024 Spaceport America Cup Rocket named "Inferno." Lots of changes were introduced between the previous version and this one including but not limited to:
- Kalman Filter from external source replaced with Jazz implementation
- Logging to RAM buffer before launch to limit storage taken up by data at the pad
- IMU and Altimeter class implementation overhaul
- IMU Calibration tool for obtaining the offsets to be used on boot instead of the BNO055 auto-calibration
While we do not have onboard footage for this launch to concretely prove the ADS' deployment, we do have the onboard logs to indicate the flaps tried and seemingly succeeded in deploying. This is supported by the fact that they seemed to have had an affect on the barometric altimeter such that the apogee transition occurred prematurely in line with when a supposed max deployment and retraction occurred (see graph below).
Additionally, an error was made in the "altimeter::set_threshold_altitude" method such that it was adding the current altitude to the desired threshold when it should not have been. This resulted in the lack of a logging end condition, but it did not affect the behavior of actual deployment.
