¹ Highly scalable depending on available resources of the processing platform
2 Positioning performance depends on atmospheric conditions signal multipath, satellite geometry as well as available corrections and their quality. A minimum of 5 satellites is assumed. All accuracies apply to Horizontal Position accuracies.
3 TTFF times apply in open sky and strong signals conditions. Hot Start is the time taken by the receiver to achieve a standard position fix after a brief outage between 30 and 50 seconds. For example, the time taken to fix a position for a car that is exiting a long tunnel. Cold Start is the time taken by the receiver to achieve a standard position fix after a prolonged outage. For example, the time taken to achieve a position fix for a car that has been parked overnight in a garage and once it sees the sky view for the first time. Re-acquisition is defined as the time taken to re-acquire position lock after brief moment of outage between between 1 and 5 seconds. For example, a car traveling under a freeway/highway overpass.
