Operating Acoustics
GNSS Module (A900-CM-GNSS)
The GNSS module is present on the RSP. It is a pluggable module that allows direct interface with the external
antenna.
Using a single GPS antenna input for both RSPs requires usage of external splitters.
Note
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023
Warning
The GNSS module is not hot swappable.
Note
GNSS Module RF Input Requirements
• The GNSS module requires an active GPS/GNSS antenna with built-in Low-Noise Amplifier (LNA) for
optimal performance. The antenna LNA amplifies the received satellite signals for two purposes:
• Compensation of losses on the cable
• Lifting the signal amplitude in the suitable range for the receiver frontend
The Amplification required is 22dB gain + cable/connector loss + Splitter signal loss.
The recommended range of LNA gain (LNA gain minus all cable and connector losses) at the connector
of the receiver module is 22dB to 30dB with a minimum of 20dB and a maximum of 35dB.
