4.14.3 GPS antenna interface characteristics
Depending on the receiver's knowledge of last position, current time and ephemeris data, the
receiver's startup time (TTFF) may vary: if the receiver has no knowledge of its last position or time, a
startup takes considerably longer than if the receiver has still knowledge of its last position, time and
almanac or has still access to valid ephemeris data and the precise time.
