FPLOG

The FP acts a delay for CSP packets. This means that an operator can record messages on ground, give them a time to be activated, and upload them to the satellite. This gives the opportunity to start experiments at times where the satellite is not in range from a ground station.

The LOG is a centralized system that records log messages from all subsystems, and saves them to flash. The log messages include:

  • Severity – i.e. info, warning, error.
  • Time
  • Subsystem that sent the message
  • Event, a even id for the message – i.e. BOOT_COMPLETE
  • Text string of up to 73 bytes

The system is capable of filtering on all but the text string. This gives the possibility of requesting specific log messages from ground.

The LOG is NOT for storing experiment data.
