GNSS Receiver
The LM960 integrates a GNSS receiver that could be used in Standalone mode and in A-
GPS (assisted GPS), according to the different configurations.
LM960 supports an active antenna.
Frequency range • Wide-band GNSS:
1559–1606 MHz recommended
• GPS:
2.046 MHz BW NB GPS (centered on 1575.42 MHz)
• Glonass (GLO):
~ 8.3 MHz BW (1597–1606 MHz)
• BeiDou (BDS):
4.092 MHz BW (1559.05 – 1563.14 MHz)
• Galileo (GAL):
4.092 MHz BW (centered on 1575.42 MHz)
Gain 1.5 dBi < Gain < 3 dBi
Impedance 50 Ohm
Amplification 18 dB < Gain < 21 dB
Supply Voltage 3.1 V
Current consumption 20 mA Typical
7.4.1. GNSS RF Front End Design
The LM960 contains an integrated LNA and pre-select SAW filter.
This allows the module to work well with a passive GNSS antenna. If the antenna cannot
be located near the LM960, then an active antenna (that is, an antenna with a low noise
amplifier built in) can be used with an external dedicated power supply circuit.
GNSS receive path uses either the dedicated GNSS connector or the shared Secondary
#0 antenna connector.
NOTE – Please refer to the LM960 AT Commands Reference Guide,
80568ST10869A for detailed information about GNSS operating
modes and GNSS Antenna selection.
