Hi?ÿ
I've used a old dual frequency?ÿreceiver " GTR 3220 " with geodetic l2 antenna . The problem is i can't find its antenna calibration in NGS site or anywhere . How?ÿ can i find that ??ÿ
A close up picture of the LABEL(s) on the Antenna would help (a lot maybe).

Here's what I get by blowing up part of his picture
and OPUS has an option for
SPP571212238+GP NONE
That probably means you can find a drawing on the NGS web site somewhere among their antenna?ÿ?ÿ calibrations.?ÿ I haven't navigated those files for a while so can't immediately help there.
Finding an antenna file is only half your problem. You have to know if it is an old relative file or a new absolute file.

On OPUS it is SPP571212238+GP NONE?ÿ

OPUS used to have photos with the offsets shown, but I can't find them any more. I have several of these units and jumped through all sorts of hoops to get them working in RTK mode and to download to OPUS. I tried to attach an OB file here, but it wouldn't let me. My biggest problem with the units was getting the 4 pin hirose cables to work. I finally gave up and bought some HiperLites. Like I said, I have several of these units, and at least one set was working in RTK mode last time I used them. I have been meaning to get them out and get them working so that maybe I could sell them. If you want them, they'll go cheap..
thank u
I also have the manuals somewhere.
Way to go Doodlebug!
