GPS Receiver Positioning Performance

NMEA sequences of three consumer grade GPS receivers of different age and prices were recorded. GPS signal obtained through a fixed, roof-mounted antenna was fed to the receivers in the lab. Their performance in quiet space weather and tropospheric weather conditions is compared. Positioning drifts caused by a solar storm and a snow storm are examined. Other positioning anomalies are described, especially diurnal height variation and constellation related effects. Overall consumer grade receiver positioning performance is evaluated.
