Use the ANTENNATYPE command to control the storage of up to five user-defined antennas. Values are entered and interpreted according to the conventions in the IGS ANTEX format.
The current list of user-defined antennas stored by the receiver can be viewed using the USERANTENNA log. The THISANTENNATYPE command and BASEANTENNATYPE command control the use of the antennas in RTK.
Message ID: 2281
Abbreviated ASCII Syntax:
ANTENNATYPE Action AntennaType [AntennaName] [NumberOfFrequencies] [Frequency] [NorthOffset] [EastOffset] [UpOffset] [PCVArray] ...
The “Number of frequencies” determines the number of frequencies for which Phase Center Offsets (PCOs) and Phase Center Variations (PCVs) are stored. For simplicity, the syntax above shows a single frequency. The ASCII Example 1 below shows two frequencies being added.
PCOs and PCVs can be defined for up to 24 frequencies.
ASCII Example 1:
