You'll find sometimes OPUS is down, even DPOS AUSPOS and other's. I've grown to dislike OPUS as it's too damn picky with submitted data or nearby CORS data is unavailable. Plus OPUS uses only GPS. I also think NGS needs to lighten up on their strict requirements (4 hours) on the GPS Benchmarks campaign. Using multi-constellations receivers and adding to OPUS would shorten occupation times.
Using Justin, I have the freedom to PP to the surrounding passive stations in our area if needed. I also can use all the GNSS constellations in Justin. For the price, you won't find anything out there to compare Justin with. I enjoy using the software, I think others would too if they'd just try it.
TBC and others aren't the know-all in PP. Justin beats them all, including OPUS in my opinion. Justin should be a standard toolbox for every Javad user.
