SIMCom suggests the LTE auxiliary antenna to be kept on, since there are many high bands in the
designing of LTE-TDD, such as band41. Because of the high insert loss of the RF cable and layout
lines, the receiver sensitivity of these bands above will have risk to meet the authentication without the
diversity antenna. For more details about auxiliary antenna design notice, please refer to document
[25].
4.3. GNSS
MODULE merges GNSS (GPS/GLONASS/BD) satellite and network information to provide a
high-availability solution that offers industry-leading accuracy and performance. This solution performs well,
even in very challenging environmental conditions where conventional GNSS receivers fail, and provides a
platform to enable wireless operators to address both location-based services and emergency mandates.
4.3.1 GNSS Technical specification
 Tracking sensitivity: -159 dBm（GPS）/-158 dBm（GLONASS）/-159 dBm（BD）

Cold-start sensitivity: -148 dBm

Accuracy (Open Sky): 2.5m (CEP50)

TTFF (Open Sky) : Hot start <1s, Cold start<35s

Receiver Type: 16-channel, C/A Code

GPS L1 Frequency: 1575.42±1.023MHz

GLONASS: 1597.5~1605.8 MHz

BD: 1559.05~1563.14 MHz

Update rate: Default 1 Hz

GNSS data format: NMEA-0183

GNSS Current consumption : 100mA (GSM/UMTS/LTE Sleep ,in total on VBAT pins)

GNSS antenna: Passive/Active antenna
If the antenna is active type, the power should be given by main board because there is no power
supply on the GPS antenna pad. If the antenna is passive, it is suggested that the external LNA should
be used.
