Are You Ready For The GPS Week Rollover?
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?
I took our Topcon Hiper II's out and tried them out. No problem with the roll over. I didn't think I would have problems but just wanted to confirm. It does appear a few people are having problems.
TN DOT runs a Topcon VRS....
Got this message a few minutes ago...
To all TDOT GNSS network clients,
We’ve been receiving multiple reports from users concerning inability to get connected to the network. We think this is due to the GPS rollover that took place over the weekend. We are communicating with Topcon representative to help get this issue resolved ASAP. We do apologize for the inconvenience.
Then a few minutes later...
TDOT IT will perform a firmware fix to the connectivity issue between 7PM-10PM tonight. Network outage may occurs during this time.
So it looks like Topcon has a fix for whatever the problem is.
My Sokkia GSR2700 ISX base and rover appear to be unaffected, end of life was a few years ago and the last firmware update was shortly before that.
The only issue I've found is that Sokkia Planning software, which I use to convert the Sokkia/Novatel .pdc file downloaded from the base into .n and .o rinex files for post processing, is producing a 1999 gps nav .n file. Novatel 'convert' software is an alternative, currently experimenting with installing that on a Windows 10 pc along with Borland database engine which it requires, both were designed to run on XP/Win 7.
