Hi dear Rocketryforum,
We are a group of students from the Technical University of Berlin. On 11.4.2022 our hot-water-rocket was launched. We used the Altus Telemtrum v2.0 board to record and transmit the telemetry of the flight. Unfortunately, the recovery system was not triggered during launch, so we are now trying to find the cause of this error.
The recorded telemetry has some inaccuracies and transient patterns. Therefore, the evaluation is more complicated than expected. First, the OnBoard telemetry and the Transmitted telemetry are often not identical and second, there are strange artifacts in both data sets. I have attachet some screenshots to understand what we mean. Additionally, you can find attached the raw (AltOs) datasets of both, OnBoard and transferred data, and a summary of the configuration of the TM board at the launch site.
Some general info about our setup:
Thank you very much for your help!
Best regards,
Marco

Some general info about our setup:
- We connected our pyro igniter for the recovery system to the Apogee igniter.
- The "Igniter Firing Mode" was set to DualDeploy.
- The Apogee Igniter Channel was successfully tested 2 times at the launchpad prior to launching
- Main Deploy Altitude was set to 250m
Thank you very much for your help!
Best regards,
Marco
