The Periodic Contract is a report sent every ... minutes
It specifies the reporting rate at which the avionics is required
to assemble and downlink the requested information to the ground system
The minimum reporting rate is usually not greater than every 14 minutes
but can vary to suit the need of the ground station
This procedure allows longitudinal and lateral separation of aircraft
in oceanic areas to be reduced to 30 nautical miles each
The Basic Report gives position - trajectory intent - speed vector data
plus the Figure of Merit code or data for navigational accuracy
