Accuracy
Accuracy is dependent upon various factors including the number of satellites
tracked, satellite geometry, observation time, ephemeris accuracy, ionospheric
disturbance, multipath and resolved ambiguities.
The following accuracies, given as root mean square, are based on real-time
measurements.
The use of multiple GNSS systems can increase accuracy by up to 30% relative
to GPS only.
Type
RTK, Multi-frequency
*
Measurement precision, accuracy and reliability depend upon various factors
including number of available satellites, geometry proximity to GNSS ground
reference station, multipath effects or ionospheric conditions.
