Hello,
I am a bit new to the OPUS world as I previously only had experience using network based RTK.
I downloaded files from two of my receivers and am not sure what to put in for rod height.?ÿ (Sokkia GSR2700ISX)?ÿ (Topcon GR-5)
When I convert to RINEX using Topcon Link do I just put in 2.000 m for the antennae height or do I need to add in the phase center offset??ÿ I am not sure if this is added in automatically based on the antennae type.
Similarly, when I upload the data to OPUS if a 2 meter fixed pole was used do I just put in 2.000 m for the antennae height or do I need to add in the phase center offset?
?ÿ
Thanks,
Erik
OPUS wants the height of the ARP above the mark.?ÿ The ARP is usually the bottom of the antenna assembly so for a 2-meter rod you would want 2.000.?ÿ Topcon may have some options, but you can look in the RINEX file (xxx.18o) with a text editor to see what ended up there before you submit it.?ÿ That line should read
2.0000 0.0000 0.0000 ANTENNA: DELTA H/E/N
No need for Topcon link. OPUS can read native formats, tps files.
Actually, OPUS ignores that line in a RINEX file and makes you enter the height manually.?ÿ
But it would be good to know what's in the file in case you decide to send it to some other service.

I have a Topcon GR-3 setup and use Topcon Link to download the cards.?ÿ The antenna height is not relevant until you send to OPUS then the height entered is 2m for my sessions with a 2m tripod or pole.?ÿ I don't convert to RINEX anymore but the Topcon Link software seems to be necessary to read the cards.?ÿ Whatever you have in the file as an antenna height does not matter the OPUS process will use what you type in

We have GR-3s as well. As Lee said above, you don't need Topcon Link for OPUS. We download the raw .tps file from the receiver and upload directly to OPUS. Make sure to enter the correct ARP height.
You can download the TPS using software TRU, Topcon Receiver Utility.
