Tight integration

[juliajing72]

I really like this code, which is easy to use and debug. Just curious whether the authors plan to write a tight integration version? I realise there are not many tight integration open source codes out there.
Thank you!

Hello,

Tightly-coupled integration is the first feature on the roadmap of NaveGo to be developed. I hope it will be implemented during this year.

But, before this we have to implement another function.

Since tightly-coupled integration uses pseudo-ranges and pseudo-range rates, we need a RINEX parser to extract these measurements from a RINEX file.

Any help on getting a RINEX parser or developing one will be appreciated.

Best regards.

Hello, Thanks for your response. I believe there are quite a few RINEX parsers in Matlab that is available to use. Actually, I have been looking into some recently. For example, this report contains codes on reading the header and data for RINEX 2.11. There's a few bugs which I ran into, but were not difficult to overcome.
