Description

Configure GNSS receiver with ACX7024 router. The GNSS receiver receives signals from a navigation satellite
constellation. The receiver gains precise phase and time information by processing these signals and delivers the
information across the packet network.
Options
cable-delay-compensation—GNSS receiver unit to router RF cable delay compensation in nanoseconds. You can specify a
value in nanoseconds to compensate the delay that the cable introduces.
• Range: -1000000 through 1000000 nanoseconds
constellation—Various constellations are available. You can configure the GNSS receiver to explicitly use a specific
constellation or combination of constellations.
The following constellations are available:
• gps: Enables detection and locking to the GPS constellation.
GPS signals enable you to determine the position of the receiver on earth and maintain a high level of time accuracy.
The GPS L1CA receiver with 10MHz clock frequency output synchronized to a GPS satellite.
NOTE: You can use only GPS L1CA to configure the GNSS receiver.
• galileo: Enables detection and locking to the GALILEO constellation.
