UltiMate GPS
Warm start — For a warm start, the GPS receiver remembers its last
calculated position, the almanac used, and the UTC, but not which satellites
were in view. It then performs a reset and attempts to obtain new satellite
signals and then calculates a new position. The receiver has a general
idea of which satellites to look for because it knows its last position, and
the almanac data helps identify which satellites are visible in the sky.
This takes longer than a hot start but not as long as a cold start. For your
UltiMate GPS accessory, the typical time-to-rst-x (TTFF) for a warm start
is < 0 seconds under clear and open sky conditions.
Cold start — For a cold start, the GPS receiver discards all current
information, attempts to locate satellites and then calculates a new position.
This takes the longest because there is no known information available. For
your UltiMate GPS accessory, the typical time-to-rst-x (TTFF) for a cold
start is < seconds under clear and open sky conditions.
