I have PM500 with v4 firmware could i update to the v6.8 ??ÿ
And what about the fast survey software of the MMCX controller in v2.3.5? Is there any chance of incompatibility?ÿ ?
Monday 25 March 2019: Update (#4 I think): PM2 and PM3 should survive with no firmware update:
See [ https://ashgps.com/2/wnro/Spectra_SupportNote_GPS_Week2048_RevD.pdf ] for latest update including additional information on:
?ÿ MobileMapper CE, CX, 6, 10 20
?ÿ ProMark 2, 3
?ÿ EPOCH 10,25
?ÿ
Mark, thank you very much for staying on top of this. Hopefully GNSS will survive.

Thank you for the update Mark.
Surprising Topcon just released NEW firmware for the old Hiper Lite series and most of their other GPS receivers this month, for the April Rollover.

Mark, this news will allow me stop banging my head against a post about my PM3s for the time being.
Will see what the rollover brings.

'End of life' my butt. These things still collect data - they are still alive and kicking. Hopefully they still work in a couple of weeks.
I was surprised to see that the PM2 isn't affected.?ÿ I haven't turned mine on in about a decade, but apparently they still work.
According to the email from Trimble we need at least firmware version 2.32; we have 4.84 on three R4-3 receivers and 5.35 on three R8s receivers so we should have a go for launch.
I have a lot of good memories using my PM3 receivers. I sold them, of the three one wasn't working but I shipped all three.
When I was using them 15 to 10 years ago they would get more satellites than the Trimble 4700s and 4800s I was using at work. Processed them in GNSS Solutions with really amazing results. GNSS solutions had a really handy ground coordinate system generator, I would routinely check coordinate pairs with my Total Station in under a hundredth.
The stop&go was like super cheap RTK, worked great. I even used them to stake out search coordinates, would routinely get me within 3' of a monument I was looking for.
I updated the two GR3s we still have. The file light wouldn't come on. It turns out the file system needs to be initialized. I got a green REC light on one, initializing the other one.
The FC500 controller is dead, on charge now so can't test RTK yet but can test static.
So the moral of the story is you may lose all the files still on the receiver so download them if necessary. The last use these ones saw was two years ago so they were downloaded long ago.
The sky is falling! The sky is falling!
GPS rollover is upon us!
I set 5 nails in the yard yesterday, in a line 5 feet apart.?ÿ I collected 2.5 hours of data with 5 receivers, 1 new Javad, and 4 older units.?ÿ I will download and process the data myself against a local CORS station and compare the results.?ÿ I will also upload each file to OPUS to verify their software is getting the same results as mine, and everything is 5ft apart and in a line.?ÿ Next week I will repeat the procedure and see if the results match.?ÿ I am only concerned with static work with these old receivers, so this is the testing procedure I came up with.
Anyone else go through testing their equipment??ÿ

I don't think you need a careful test of accuracy.?ÿ With this change, either it will process or it won't.

I was told Topcon ran some tests. They concluded that receivers made after 1999 will survive tomorrows rollover, even without the suggested firmware updates. Basically, those that do not update the firmware will have clock issues that will likely take much longer to initialize. However, accuracy should not be affected.
I hope this is the case. My Hiper+ and Legacy E+ don't have memory so I am unable to upload the firmware, still trying to find a work around. Is it possible to install some memory in these myself?
