Definitions
* Specifications will vary depending on the number of satellites used, obstructions, satellite geometry (PDOP), multipath effects, and atmospheric conditions. For maximum system accuracy, always follow best practices for GNSS data collection.
** Not using DGPS and crossing the start/finish line at 100 km/h.
*** Approximately 29 MB per hour used when logging GPS data at 100 Hz; Approx. 182 MB per hour total logging capacity.
