I recently watched OPUS-Projects for RTK/RTN Vectors at OPUS-Projects for RTK/RTN Vectors | Webinar Series | National Geodetic Survey. Please notice the date of the video; It's over 4 years-old. I've been studying the video and have not seen any indication that the described software (OPUS-Projects 5.0) has reached maturity and is currently being used. I'm looking for a faster method than static GNSS for setting control points for a 1000' long topo of a paved road, which includes above-ground utilities and an overlap of the right-of-way lines. Once again, this will be a mix of GNSS, total station, and digital levels. There is no possibility of a closed loop traverse, so I will use a closed traverse with 2 control points at each end. The plat of the project is built off of a section line with recovered corners along a quarter-section line. I'm hopeful I can tie my control points and traverse points into that line.
I tried to bluebook a large project (60-ish stations) last year using OPUS Projects with RTN and PP vectors and following the NGS-92 protocols, but kept crashing the software. Despite lots of assistance from NGS staff, we were never able to resolve the problems. I also had a lot of QC failures, so I'm skeptical about the RTN specs, at least with the receiver I was using (GPS and GLO only).
I think it would probably work fine for smaller projects that don't need bluebooking.
I have gone through training for OPUS Project and it is different than the traditional static network of old days to say the least.
For a 1,000 foot traverse and topo job I think I would just OPUS on the ends, let them float a little in the least squares adjustment of the traverse and be done. Your traverse work is going to be tighter than the GPS, the OPUS solutions will get you on grid within a cm or two and give you a check for any blunders in the traverse.
