Drawbacks of the previous method: when writing to the SD card, there are high delays in the write() call of several 100ms, every now and then. The frequency and length of these events depend on: - SD card - used logger bandwidth - bandwidth of gps data (RTCM) Since the whole gps thread was blocked during this period, it lead to gps timeouts and lost module. What we do now is: publish an orb topic with queuing. This makes it async and the logger takes care of buffering. This means it's best to: - use high logger rate - use large logger buffer - reduce logger bandwith by disabling unused topics
