RTKANTENNA

Specifies L1 phase centre (PC) or ARP and enables/disables phase centre modeling

Platform:

OEM719, OEM729, OEM7500, OEM7600, OEM7700, OEM7720, PwrPak7, CPT7, CPT7700

Use this command to specify whether to use L1 phase centre or Antenna Reference Point (ARP) positioning.

There is also an option to apply phase centre variation modelling. If there are any conditions that make a selected mode impossible, the solution status in the position log will indicate an error or warning.

L1 ARP offsets and L2 ARP offsets can be entered using the BASEANTENNAPCO command and THISANTENNAPCO command. Phase centre variation parameters can be entered using the BASEANTENNAPCV command and THISANTENNAPCV command.

Error states occur if either the rover does not have the necessary antenna information entered or the base is not sending sufficient information to work in the requested mode. An example of these error conditions is:

• Position reference to the ARP is requested but no rover antenna model is available

Message ID: 858

Abbreviated ASCII syntax:

RTKANTENNA posref pcv

Factory default:

RTKANTENNA unknown disable

ASCII example:

RTKANTENNA arp enable

This command is used for high precision RTK positioning allowing application of antenna offset and phase centre variation parameters.
