Automatic Multi-Constellation, Multi-Frequency
When using TerraStar service, a multi-constellation, multi-frequency channel configuration gives better
accuracy and faster convergence time compared to a dual-constellation, dual-frequency channel
configuration. To allow the receiver to make best use of the TerraStar subscription, a multi-constellation, multi-
frequency configuration is automatically activated included with TerraStar-X, TerraStar-C PRO or
RTK ASSIST PRO subscriptions.
To enable multi-constellation, multi-frequency channel configurations, issue the following commands:
TERRASTARCHANCONFIG ENABLE
SAVECONFIG
If a TerraStar-X, TerraStar-C PRO or RTK ASSIST PRO subscription is active, a receiver reset is required
after issuing these commands.
For more information, or to disable Multi-Constellation, Multi-Frequency channel configuration, see the
TERRASTARAUTOCHANCONFIG
command.
If the TerraStar-X, TerraStar-C PRO or RTK ASSIST PRO subscription becomes inactive, the
receiver will revert to the channel configuration enabled by the receiver model.
This feature is available on OEM firmware version 7.06.01 and later.
