The accuracy specifications refer to the PRTKA/B logs which include about 3 cm extrapolation error. RTKA/B logs are more accurate
but have increased latency associated with them.

After 30 seconds reverts to pseudorange positioning (single point or differential depending on messages previously
received from the base station).
