@nate-the-surveyor Before long it??ll be: ??that??s not like your dad??s GPR??ÿ
as was noted above:?ÿI??ve gotten that several times. And if the interval 15 seconds BUT the first 1-3 epochs are not 15, it quits. I delete the firs...
@oldpacer What I meant is the accuracy of 20 yr old duel freq gps only receivers and new receivers are the same. Gps only fixed integer static baseli...
So, I uploaded the Rev E week rollover fixed firmware into my ZSurveyor. And I collected a couple of hours, then simply downloaded the file. That ret...
@robots i just loaded the firmware in my ZSurveyor. It works (ie: it didn??t brick it.) Rev E, week roll over fix confirmed. And my ZSurveyor is no...
@bill93 There's always that. The issue with Z receivers is the internal battery replacement. I??ve replaced the batts in all of my receivers. They ...
@jonathan50 Surprisingly, a good geo antenna, gps only, are going for as much or more than the antenna. And most of the receivers have no cable or an...
@whewison Absolutely. I use them (Z12, ZSurveyor) regularly. I have a rinex date fixer executable. So, after download, -> rinex, and run a fixer w...

@larry-best good to know.?ÿ
@larry-best Your agreement with additional contemporary opus derived positions is good. But that still leaves the question of how old the underlying ...
@bill93 yes, I??m looking for those values. The formula is: PPM= C - (Dp/K?ø) p is pressure ?ÿ The EDM specific constants are: C and D.?ÿ This ...
I??ve a question about Trimble S instruments: where can I find the EDM constants for PPM calculation? Commonly known as ??first velocities??. I?...
@paul-in-pa ZXtreme and ZSurveyor cables are compatible. (99% sure) The Fischer connector shell is labeled 102 (shell size). The Z-XII cables are hug...
@robots I use my ZSurveyors pretty often. So they??re not display pieces. The real benefit is that most software, including OPUS, will read the Ash...
@robots I have the firmware flash files: ZC00 and ZB00 and the universal program loader. I have two ZSurveyors, one with ZB00 and one with ZC00. And...
@robots That was an autocorrect. I intended got not hit. So what Ashtech firmware have you fixed for week rollover??ÿ
@robots There??s a thread a couple months ago about week rollover firmware fix for one or two Z models. A programmer hit the source code and fixed...
@bill93 What software? TEQC? I have an excitable that simply corrects the date in rinex. Just one click, but it only works 2.11. It just adds 1024 w...
@jonathan50 its fully tested. And it is week rollover afflicted. No leap second issues, GPS has no leap seconds, only UTC does. (GPS satellite only, ...
