Accuracy and reliability may be affected by external factors such as multipath, obstructions, satellite geometry, and atmospheric conditions. It is recommended to set up the instrument in an open area with no significant electromagnetic interference and multipath environments. When the baseline is longer than 30 kilometers, precise ephemeris is required, and it may take up to 24 hours of observation to achieve the high-precision static standard indicators.
Severe vibration and rapid rotation may affect inertial navigation accuracy.
