PreFlight Testing

1. Manual Testing

There are many tests in our integration suite that are tagged manual and do not run on integration testing. We should cover all these cases.

Currenly I think these are just some Mode Manager Tests.

2. Startup Testing

In nominal conditions, does the satellite startup from being deployed, wait 45 minutes, run all its startup commands and beacon. Can a listening ground station listen to it and command it? Check boot count and mode_state files

We also want to test the satellite starting up in a number of configurations:

• Starting up in normal mode
• Starting up in safe mode
• Starting up when command loss time set off
• Starting up in detumble
• Starting up with no startup sequence

3. Day of the life testing

Using the Radio as an operator, uplink the sequences and run the day in the life tests (test_day_in_the_life.py). These include

• Changing the radio settings with radio_fast.seq
• Running payload operations using
• Running the edge cases in day of the life
• Downlinking files (ex Photos, Telemetry on Boot)

4. Over the Air update Testing

• Do an over the air update over the radio. Test that you can revert back to the golden parition on command loss, commanded reset and/or fault from the test parition.

5. Payload Testing Because these satellites have specific non-camera payloads, Run the payload in nominal and off nominal conditions. This includes getting data down.

• Nominal acquire + store + Downlink
• Power off / on cycling on operation
• Command while safe mode
• Payload fault, check if goes into safe mode when it can
• What happens on a broken filesytem or RTC

6. Stress Testing

This is a big one, we only realized we had RAM issues last time because we ran stress testing and observed abnormal behavior. Have everything be on for a longer period of time, and stress the system

• All load switches on + detumble AUTO + LoRa TX + high telemetry rate, Three sequencers concurrent
• Rapid command uplink (auth + bypass)

7. Telemetry Testing

Check we get all the telemetry we need as we toggle the different levels of telemetry.

Run startup with nothing in pre_deployment.tlm, then downlink it when its done

Edge Cases

• Filesystem Stressing: Power loss while writing, Continous file creation writing
• RTC: Time Set Command, Time Set being removed. What happens to Detumble/sequences/any compnent that depends on time

Test satellite jamming with two spacecraft and run the startup
