RINEX support

[cplaursen]

Hi,

I can't see the RINEX format mentioned anywhere in the documentation, so I'd like to request a RINEX conversion command. Would this be feasible? I'm happy to assist in the implementation.

Hi @cplaursen ,

There's currently no RINEX conversion functionality in pygnssutils, though this is not the first time it's been requested.

Developing a Python RINEX conversion utility from scratch would not be a trivial undertaking, and I simply haven't had the time (or frankly the motivation) to do this single-handed on a voluntary basis. I'm also not sure how many takers there would be for a Python tool given the ubiquity of Tomoji Takasu's C RTKLIB libraries, which probably involved 100s (if not 1000s) of development man-hours for the RINEX stuff alone.

But I am very happy to consider contributions if there's a wider appetite for such functionality.

Defining the scope would be the first step - what version(s) of the RINEX protocol would you be looking to support, given the emergent RINEX 4 standard? Which raw conversion sources would you be looking to accommodate - NMEA? UBX? RTCM? SPARTN? anything else? What specific functionality would you be after?

Thanks for your reply!

It seems logical to target RINEX 4, although looking at the software I'm personally looking to use it would be good to have 3.04 support too.

I'd like to have support for UBX and RTCM. The main functionality I'm looking for is RINEX conversion, with PPK support being ideal but presumably not feasible in the short term.

I understand that it would be a lot of effort. I'm working with this as part of my job, so I'd be able to put in some work in the medium term towards implementing this if, as you say, you're happy to take contributions.

Hi again @cplaursen You're very welcome to contribute if you have the time - it would certainly be good to have PPK support. There are a few Python repos out there already but no complete solutions that I'm aware of.
