  • Adds time handler component in Core Controller
  • If the fix type has changed inside the GPS handler, a dedicated event will be generated
  • Core Controller listens for this events and keeps track of GPS fix
  • If a fix is available, it is assumed that the system time is set by ntpd. In that case, regularly back up the current Unix time inside a file
  • If the SW is rebooted and the GPS is not available, set the clock with the time backup file
  • Related PR: eive/eive-tmtc#54
  • For some reason, time has to be set to a sane value for NTP to be able to reach the GPSD data (???????).
    • For now, the core controller AND the gps controller will perform a sanity check on the time at software startup and set it to some remotely correct value. The sanity check simply checks whether the year of the unix timestamp is 2000
    • This can be either the one from the time file in case of the core controller or the GPS time which is received correctly from GPSD in case of the GPS controller.
    • I would prefer trying out a program like chrony or properly installing ntpd, gpsd and all the other stuff properly with yocto, but there is not much time for this.
