B.14 SBASCONTROL Set SBAS test mode and PRN
This command allows you to dictate how the receiver handles Satellite Based Augmentation System
(SBAS) corrections.
To enable the SBAS position solution corrections, you must issue the SBASCONTROL ENABLE
command. The GNSS receiver does not attempt to track any SBAS satellites until you use the
SBASCONTROL command to tell it to use either WAAS, EGNOS, or MSAS corrections.
When the system parameter is set to AUTO mode, if the receiver is outside the defined satellite
system’s corrections grid, it reverts to ANY mode and chooses a system based on other criteria.
Once tracking satellites from one system in ANY or AUTO mode, it does not track satellites from
other systems. This is because systems such as WAAS, EGNOS and MSAS do not share broadcast
information and send corrections relevant to their specific geographic region.
The “testmode” parameter in the example is to allow SBAS operation while SBAS systems are in test
mode. At the time of printing, the testmode parameter of NONE is recommended for all SBAS
systems.
When you use the SBASCONTROL command to direct the GNSS receiver to use a specific SBAS
system, the GNSS receiver begins to search for and track the relevant SBAS PRNs for that correction
type only.
You can force the GNSS receiver to track a specific PRN using the ASSIGN command. You can force
the GNSS receiver to use the corrections from a specific SBAS PRN using the SBASCONTROL
command.
Disable stops the corrections from being used.
