This year I'm going to try to get back into dual freq. gps. by picking up something used. I'm looking at the Topcon Hiper GGD as a possible choice. It looks to be upgradable to RTK or network RTK ... But for now, I'm just looking for something that will log data and post process, or submit to OPUS.
Would I need to buy topcon software to get the data files off the unit, and create Rinex files, or is there freeware or another way to retrieve the files?
Any suggestions as to what I should be looking at?
Thanks
Topcon Link will download and convert to RINEX, but not post-process. It is free from their web site.
I have been using a Hiper along with my old Ashtech stuff. It is really a fine receiver!
Yeah, that is my plan too. OPUS and using with my Old Ashtech gear, for now. I can process (L1 Only) in Ashtech Solutions, so I think I can incorporate the Opus solution and the Hiper into post processing that way.
You can download the receiver with free ware from Topcon. Then you can convert to rinex if needed with a demo version of Topcon Tools (demo does not expire). But you don't need rinex for opus, you can send your Topcon files.
I would recommend the Hiper Lites because that is what I know and what I use. I bought mine used and 1 at a time. The first one I used for opus until I got the right job where I could afford/justify the second one for RTK. Once you have 1 good day and the right job with RTK you will wonder how you ever lived without it.
And beerleg is a great learning tool. If you have a question about the equipment or procedure someone here has done it before and is normally willing to share.
You can send your topcon files (.tps) right out of the receiver to OPUS... no need to convert, OPUS will convert them. You will need PC-CDU to retrieve the files, but it is free from the Topcon site.
I would not get the Hiper GGD... it is an older unit and part maybe scarce.
AND a GGD receiver will log the Glonass as well as the GPS, thus putting a lot of useless data in your file and using up memory... you will need at least 8MB in a GGD unit. ...The GGDs are better for RTK though.
Thanks for the input. I wasn't sure about the timetable of the GGDs. I used Hipers too, at a past job. I really liked them, but they also are locked up by Topcon with pay-to-play "upgrades" (distance range, comm ports, Glonass, memory, etc.). You have to watch it with Topcon Hipers, you can't use them as static receivers unless you've paid to unlock the memory.

Unless you use PC-CDU, to log directly to the computer.

If you are using a HiPer receiver for OPUS with the GLONASS tracking enabled, you can easily turn the GLONASS tracking off using PC-CDU or Topcon Receiver Utility (TRU) so you don't fill up the memory with data that are useless for OPUS solutions.
You can also use the Cinderella days for static occupation days when you only need to use OPUS once in a while.
This unlocks the receivers for more than what you paid for every so often. There is a schedule posted somewhere.
It might help those out that are on a tight budget.

Was the Cinderella feature included on all receivers? I though the was it extra-cost option.
OPUS only uses 30 second epochs. If you are collecting at a higher rate the OPUS software decimates the shorter epochs taken at 10 or 15 seconds for example. By setting the receiver to 30 seconds a lot of memory is conserved. I am assuming we are talking Rapid-Static observations.
