To set a Remora, or Oyster Cellular, to only send a position update on a set interval, first add the Advanced Tracking parameter, and set Periodic Tracking Only to Yes



After pressing Update, periodic tracking will be enabled the next time the device connects to the server. The default period is 12 hours, but to change this, also add the Basic Tracking parameter, and change Heartbeat Upload Period to the required period (in Minutes). 



Please take into account that for parameters to take affect (as well as enabling recovery mode), the device needs to connect to the server when choosing the upload period.
