positioning requires either a data link between the two stations (if the positioning is to be achieved in
real-time) or else post-processing of the data collected by the remote station. At least four GPS
satellites in view are still required. The absolute accuracy of the remote station’s computed position
will depend on the accuracy of the reference station’s position.

Static vs. Kinematic Positioning
Static and kinematic positioning refer to whether a GPS receiver is stationary or in motion while
collecting GPS data.

Real-time vs. Post-mission Data Processing
Real-time or post-mission data processing refer to whether the GPS data collected by the receiver is
processed as it is received or after the entire data-collection session is complete.
