1. A method for analyzing Global Positioning System (GPS) measurements, the method comprising:
- providing GPS receiver data from a GPS receiver;
evaluating, by a computer, a measurement quality of the GPS receiver data, thereby obtaining measurement quality metrics;
obtaining GPS metrics from the GPS receiver data;
evaluating, by a computer, a positioning quality of the GPS receiver data, by analyzing the GPS metrics with a computer, thereby obtaining positioning quality metrics; and
displaying to a user the measurement quality metrics and/or positioning quality metrics.
