PPP with ambiguity resolution products? #518

Open MertBezcioglu opened 4 years ago

MertBezcioglu commented 4 years ago

Which fcb products should I use to provide ppp-ar solution with rtklib? I have already used fcb products from wuhan and cnt biases files. But i did not see the differences of solutions between them. RTKLIB gave the same results in PPP-AR mode with both products. Where am I doing wrong? What is your suggestions?

PPP-AR is not supported yet.

Is there anything that could be done to help contribute to PPP-AR? It looks like there's a random fork of RTKLIB with it at https://github.com/heiwa0519/PPP_AR and there was an original description of PPP-AR in RTKLIB in 2012 but it was removed since[1]. Was that code buggy or needed some other fixes?

The codes for PPP-AR in RTKLIB v2.4.2 had been developed under the contract with JAXA. They had a license problem to be published as OSS. So they were removed from the public repository.

Ah, thanks. That's a shame. There's way too much government-funded-but-kept-closed-source stuff in PPP (eg NAPEOS)...Would you be interested in building it again under a public (maybe crowd-sourced) funded contract instead of one requiring it stay closed-source?
