GPS receiver
Number of SV
1
1. SV = "space vehicle". Max. number of satellites the receiver can use to determine position or
time. The satellites providing the highest signal quality are considered. In general, the receiver
only needs 4 - 5 satellites to determine position and time — depending on the signal quality.
12 (satellites)
TTFF (time to first fix)
2
2. TTFF = Time span the CMGPS needs to receive a sufficient number of satellite signals after
switching on (to be "locked" to the signals). The higher the synchronization accuracy set via
software (optimum: abs. error < ± 1
μs), the longer the time span will be.
Typ. 5 minutes
(for a set accuracy of < ±1 µs)
Typ. 3 minutes
(for a set accuracy of < ±10 µs)
Position fault < 5 m (16.4 ft) [1 σ]
Identification antenna status OK, short circuit, defective
