13.5.2 GNSS (Global Navigation Satellite System)
13.5.3 Conducted RX sensitivity (LTE Bands)
Parameter Description
Satellite channels 12 channels, continuous tracking
Frequency Narrow-band GPS:
1575.42 MHz
Wide-band GPS and GLONASS:
1565 MHz ... 1606 MHz recommended
Protocols NMEA 0183 V3.0
Acquisition time Hot start: 1 s
Warm start: 29 s
Cold start: 32 s
Accuracy Horizontal: <2 m (50%); <5 m (90 %)
Altitude: <4 m (50%); <8 m (90 %)
Velocity: <0.2 m/s
Sensitivity Tracking
a
: -161 dBm
Acquisition
b
(Assisted, non-LTE): -158 dBm
Acquisition (Assisted, LTE): -153 dBm
Acquisition (Standalone): -145 dBm
a. Tracking sensitivity is the lowest GNSS signal level for which the device can still detect an
in-view satellite 50 % of the time when in sequential tracking mode.
b. Acquisition sensitivity is the lowest GNSS signal level for which the device can still detect an
in-view satellite 50 % of the time.
Operational limits Altitude <6000 m or velocity <100 m/s
(Either limit may be exceeded, but not both.)
