@lurker Chalk one up for older kit: unrestricted. Everything is subscription these days.?ÿ
@lurker interesting. the question is: is that user input, and does that terminate operation. I don??t know what to make of that. My Ashtechs (z12 a...
@jerrys I looked thru several manuals and the OAF settings. I did not find any reference to a ??window?? of operation. More importantly, in the manu...
@norman-oklahoma?ÿ well if there are geolocked GNSS receivers, I??d like to see a citation of that. And that would definitely be in the documentatio...
@norman-oklahoma?ÿ Then don??t buy from a dealer overseas. Ok. Plenty of us take our US procured GPS/GNSS kit and work internationally without issue...
@norman-oklahoma You can??t be serious. The documentation of the instrument which you can read in advance. And GNSS instruments are not specific to ...
A GNSS receiver will clearly state if it??s GPS only, or GPS/GLONASS compatible, or Galileo and/or BeiDou. And what DC voltage is supplied on the ant...
Antennae have specific freq responses. So a GPS antenna works world wide. A GLONASS GPS GALILEO antenna works world wide. The receiver has to be compa...
@bill93?ÿ of course a dime. The point was that the ??dime?? sized uncertainty of each solution, in very close proximity to each, returned an invers...
@john-putnam?ÿ ICBM (not icmb) is intercontinental BALLISTIC missile. The ??B?? means something?ÿ
@dc-kelley?ÿ Thats what I had assumed: the signals at the antenna?ÿ
@shawn-billings I live in the Shenandoah valley, Hagerstown MD. There are several radio towers on the mountain ridges visible all across the valley. ...
@jim-frame I believe the receiver time is the time at the antenna. And NGS log sheets detailing antenna length. Operative word: old logs. In compiling...
@john-hamilton?ÿ Just like when the Navy stopped sextant training. A couple years later they reversed that decision for this very reason. Surveying w...
I use my T2 and T3 a lot. I used to do a lot of star shots. But I get about 3? with solar, so I haven??t done much night work in the past couple of...
The signal and time offsets are at the antenna. The data stream doesn??t get rearranged in the antenna cable. Even back in 1987 our Trimbles came wi...
BTW, The download32 I use for my Ashtechs is v 2.94 dated 2012. ( crazy that it??s Copyright Trimble)?ÿ
I assumed a couple of navigation satellites in lunar orbit would be required. But 100 m wouldn??t be embraced, it??s just feasibility testing.?ÿ
I send ZSurveyor Bxxxxyyy.dat files to opus routinely. I like that opus recognizes the Ashtech Z legacy vendor format. I can??t send Z-XII data in B...
