I'm wondering if others have experienced bad RTK fixed positions utilizing the factory "boundary" settings. I'm talking about shots that have been through the entire validation, verification, etc. process utilizing the settings as they come from JAVAD.
I'm working on a boundary retracement which includes several lines which have been surveyed a couple of times over the past 30 years and I had a bad RTK shot as described above on a monument where the record position based on two previous surveys is approximately 4' from the position I measured.
I'm utilizing a T2 base set in an open field about 3,000 feet from the site. The shot was in tough conditions and it appears that the fixed position from DPOS is pretty close to the previous surveys. Having the DPOS position is a great check on the RTK results, but in general, I've found the RTK results that go through the entire process as noted above are very reliable and certainly more so than the DPOS results. Any time I need to rely on DPOS for a shot, I will have redundant shots to verify the position.
I don't suppose JAVAD is still offering a pile of cash if you can get a bad fixed shot like this? On that note, does anybody know if that prize was ever actually won by some lucky (or unlucky) surveyor?
It's always good to have reminders that there's no substitute for checks on our work and I look forward to feedback from others on this.
