Hot Start
Hot-start functionality allows GNSS Compass to quickly start inertial navigation
A battery system within GNSS Compass provides the hot-start ability for many hours without power. When GNSS Compass hot-starts, it assumes that it is in the same state it was when it lost power and begins navigating from that position.
Whenever GNSS Compass is without power it continues to accurately keep time so that it is immediately valid for a hot-start.
The hot-start functionality is of particular benefit to vehicle tracking and robotics applications. The primary benefits are immunity and fast recovery from power failure as well as fast start up time.
