constellation {gps | gps-glonass}
config>card>mda>gnss
This command configures which GNSS system or systems will be used by the GNSS receiver. The configuration can be modified only when the GNSS service is shut down.
gps
configures the GNSS receiver to use the American GPS GNSS system
configures the GNSS receiver to use both the American GPS GNSS system and the Russian GLONASS GNSS system
nmea
config>card>mda>gnss
This command enables the context for configuring NMEA parameters.
sentence-types sentence-type [sentence-type...(up to 4 max)]
config>card>mda>gnss>nmea
This command configures NMEA sentence types that are sent from the GNSS receiver over the associated IP transport service when the service is configured for NMEA streaming. The following sentence types are supported: GGA, RMC, VTG, and GNS. For information about the sentence types, see NMEA 0183, Standard For Interfacing Marine Electronic Devices.
At least one sentence type must be specified, up to a maximum of four. Different sentence types can be specified concurrently so that multiple sentences can be streamed per NMEA sentence interval.
gga
an NMEA sentence type to be streamed
sentence-interval interval
config>card>mda>gnss>nmea
This command configures the intervals at which NMEA sentences are retrieved from the GNSS receiver and sent over the associated IP transport service configured for NMEA streaming.
5 s
time, in seconds, between the sending of NMEA sentences
[no] shutdown
config>card>mda>gnss>nmea
This command enables or disables NMEA streaming from the GNSS receiver. The no form of the command enables NMEA streaming. Using the shutdown command disables NMEA streaming.
The node uses an IP transport service to send NMEA sentences from the GNSS receiver to remote hosts. For information about enabling IP transport for NMEA sentences, see the 7705 SAR-Hm and SAR-Hmc Main Configuration Guide, "GNSS NMEA data IP transport service".
shutdown
[no] shutdown
config>card>mda>gnss
This command enables or disables the GNSS service on the GNSS receiver. Enabling the GNSS receiver causes MDA 1/1 to reset under the following conditions:
when the configuration of the constellation command changes
the first time the GNSS receiver is enabled after a firmware update of the cellular MDA
The no form of the command enables the GNSS service. Using the shutdown command disables the GNSS receiver and resets the position fix and associated information.
