①
Mode = Static or Kinematic (during initial ambiguity resolution)
②
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.
③
Between 30 and 60 seconds assumes pseudorange differential positioning. If Type 1 corrections have not
been transmitted, the accuracy drops to single-point mode after 60 seconds.
