Connecting the GNSS Input

Typical installations include GNSS as an external reference input. If the GNSS receiver is not installed or if the GNSS will not be used as a SecureSync reference, disregard the steps to install the GNSS antenna and associated cabling.

1. Install a GNSS antenna, surge suppressor, antenna cabling, and GNSS preamplifier (if required). Refer to the documentation included with your GNSS antenna for information regarding GNSS antenna installation.

   Note: The SMA-to-N-type conversion cable included in the ancillary kit is approved for pull weight of up to 60 lbs. If you are using a heavier cable, you will need to apply appropriate strain relief.
   

   For additional information on GNSS antenna installation considerations, including cabling, a Safran tech note is available here.

2. Connect the GNSS cable to the rear panel antenna input jack.
   

Initial synchronization with GNSS input may take up to 12 minutes (approximately) when used in the default stationary GNSS operating mode. If using GNSS, verify that GNSS is the synchronization source by navigating to MANAGEMENT > OTHER: Reference Priority: Confirm that GNSS is Enabled, and its Status for TIME and 1PPS is valid (green).
