Topcon Tools PP error

I started getting some gross errors post processing static observations in Tools a week or so ago.
My dealer said it was a bug in the software, wasn't getting all of the almanac or something.
Since its EOL, there's no proposed fix for it.
Anybody else had similar problems?
Anybody got a work around for it?
If not, What's a good economical PP package to switch to?
Also looking at some new GPS equipment, not topcon.
TIA

CHC GPS have a post processing software for about $250. I think I read somewhere before that it uses the same software engine as one of the big manufactures.

Why Topcon GPS no more?

I'm just aggravated over this. I paid a pretty good price for the software package, as well as the hiper lites +, now they're all EOL and they don't seem to care.
They don't even bother to post or notify anyone that there is a problem, much less fixing it, which would probably be pretty easy to do.
I've used Topcon equipment exclusively since I've been in business, and loyalty don't mean diddly squat to them.
The winds of change are blowing in a new direction. I'm looking for a company that at least acts like they appreciate their clients, but may not find them.
They probably approach Microsoft in client appreciation, which is none, or less.
Oh, well, I appreciate my clients, anyway. I think my dealers do, too, it's the high and mighty manufacturers that don't give a rip.
They will never miss little old me.
btw, thanks for the tip, I'll look for them.

I am using Topcon Tools but not noticing anything in particular. Would you mind giving more details in case I am missing something.

For instance, on one observation of 18 minutes, the solution said "Failed, No Satellites, not enough data". Others indicated high standard deviations, and float solutions that should have been fixed.
These are observations that may be under partial cover, or not in ideal conditions, which is why I was doing static observations as an addional check on rtk solucions.
I haven't had problems like that in the past.
My dealer said that he had had phone calls form several others that experienced similar problems.
Perhaps it is just a US thing? I don't know.
A dealer sent me a trial on the CGO office software to try out.
I also got a trial of the Carlson PP software, but it is going to be out of my budget at over $1800.

JT have you tried a reinstall of the software? That's assuming you have it on disk.

There is an issue with topcon tools and magnet tools. I was told using the tps2rinex conversion program is a temporary solution

Not sure if you've got the same problem I've been having with my two Hipers (which have run well without serious issues since '04) and Tools version 8.2.3, but here's my saga/solution:

I was repeatedly getting "cannot process any of x [all of my] vectors" messages, & "Failed, No Ephemeris" notes

My workaround so far has worked well (and is pretty quick & easy):

In the "Job" menu click "Import From Internet" this brings up a box that self-populates with data suitable to my downloaded observations (presumably requires an internet connection). Then I click the "Search Points" button at the bottom of the box. "No match points" may appear briefly, or maybe some options for other nearby points to use in the solution. Then 2 or 3 ephemeris [= almanac] options promptly appear. Click the GPS option & then the "Import Selected Files" button up above all this. The ephemeris quickly imports itself and then I proceed with post-processing as usual. This has bailed me out of some looming disasters recently. I don't want to know what my dealer would tell me about how much money a full-scale repair would cost. Likely they'd try to sell me new equipment and software, which I can't afford right now.

Cee Gee,
That did the trick! Maybe your work around will get me by until I can make a better decision which route I want to go.
What I've been looking at is really hard to wade through. I guess I'm just old and set in my ways.
Thanks for sharing.

Very pleased to have been of assistance. GPS is such cool technology -- until it's not.

I am thinking that the problem may be in the receivers, not the software, but I'm not sure.

Topcon published a Dealer News a few days ago about this problem. Something has apparently changed about the information included in the broadcast ephemeris such that all Topcon receivers are experiencing an issue when post processing of the data is attempted. This seems to apply to all Topcon receivers and not just the old HiPer series and related parallel units. Below is the message we received.

Missing orbit information in GNSS receivers
A post processing issue has been identified in MAGNET Tools, Topcon Tools and Topcon Link. This bulletin provides a temporary workaround until addressed in an upcoming release.

The suggested workaround is to convert the Topcon *.tps files to RINEX before attempting to post process. I have had three customers send files to me and this recommended action works for some files and not others. It does seem that files of shorter length than the time required for the emphemeris file to cycle do not typically work even after converting to RINEX.

Is it that the receivers are not properly receiving or recording the broadcast ephemeris, and the fix is to download the ephemerii within the PC software?

Edit: how long does it take for the broadcast ephemerii to completely download to the receiver?

A LONG time ago, I was told about 8 minutes, so to collect for 15 to ensure you got a full cycle.

So if it is the ephemeris download problem in the receivers, how about loading it manually via: https://igscb.jpl.nasa.gov/components/prods_cb.html

Or when downloaded a CORS file, ask for the ephemeris to be included?

That would really not be a huge deal - but annoying.

I think it's in (both your and my) receivers, too. Which is why I suspect any solution my dealer or Topcon may offer will likely be pricey.
