Accuracy, baseline rms Accuracy in position = baseline rms. Accuracy in height = 2 x accuracy in position
 
Baseline rms with post processing With SKI-Pro L1/L2 software
Static (phase), long lines, long observations, choke-ring antenna 3mm + 0.5ppm
Static and rapid rapid static (phase) with standard antenna 5mm + 0.5ppm (rms)
Kinematic (phase), in moving mode after initialization 10mm + 1ppm (rms)
Code only Typically 25 cm (rms)
 
Baseline rms with real-time/RTK Real-time/RTK standard
Rapid static (phase), Static mode after initialization 5mm + 0.5ppm (rms)
Kinematic (phase), moving mode after initialization 10mm + 1ppm (rms)
Code only Typically 25cm (rms)
 
Baseline rms with DGPS/RTCM DGPS/RTCM standard
DGPS/RTCM Typically 25cm (rms)
 
On-the-fly initialization Real time and post processing
Reliability of OTF initialization Better than 99.99%
Time for OTF (on-the fly) initialization Real time: Typically 10sec with 5 or more satellites on L1 and L2
Post processing: Typically 40 seconds with 5 or more satellites on L1 and L2
Range for OTF (on-the fly) initialization Typically up to 20 km in normal conditions with standard radio. Up to 30km in favourable conditions with powerful radio.
 
Note on accuracies and time Baseline rms, accuracy in position and accuracy in height are dependent upon various factors including number of satellites, geometry, observation time, ephemeris accuracy, ionospheric conditions, multipath etc. Figures quoted assume normal to favourable conditions. Times can also not be quoted exactly. Time required are dependent upon various factors including number of satellites, geometry, ionospheric conditions, multipath etc
 
Navigation position 5-10m rms for each coordinate
