Trajectory Accuracy

What is a trajectory

· A trajectory is the combination of a static (Base Station from a provider or from a site set as a reference) and a kinematic (rover) data file that are recorded simultaneously. These observation datasets allows differential post-processing.

· The well-known RTK mode is simply a trajectory computed in real-time in differential positioning mode. In that respect, the Post-Processor can be seen as an offline RTK application.

· In EZSurv a kinematic datafile is known as a “Rover” file.

Trajectory Accuracy

Horizontal Accuracy :           10mm + 1.0ppm or better


Vertical Accuracy :               15mm + 1.0ppm (or better)

Precision and reliability may be subject to anomalies due to multipath, obstructions, satellite geometry, and atmospheric conditions. The specifications stated recommend the use of stable mounts in an open sky view, EMI and multipath clean environment, optimal GNSS constellation configurations, along with the use of survey practices that are generally accepted for performing the highest-order surveys for the applicable application including appropriate kinematic antenna manipulation. Kinematic file distant by more than 30 km from the reference station may require precise ephemeris to achieve the high precision kinematic specification.
