A GNSS reflectometry software package
Project description
gnssrefl
github version: 2.1 
2024 January 4: subdaily now allows multiple years of results. An orthometric height correction can also be applied.
For those of you trying to convert RINEX 3 files to RINEX 2.11, be careful. There are a lot of things going on in that translation. It is better to let gnssrefl to do that conversion for you. rinex2snr allows RINEX 3 files!
Documentation:
See documentation for gnssir_input for new refraction models.
August 2, 2023: Updated azimuth outputs for gnssir and quickLook so that the azimuth of the rising or setting part of the arc is reported rather than the average azimuth, as was done in the older versions.
July 7, 2023: The newarcs option had a bug in it: the refraction correction was not being applied. While the refraction correction is not very important for some applications (snow, soil moisture), using it sometimes and not using it other times IS NOT GOOD. You will see a bias in time series when you switched. This bug is fixed as of version 1.4.1 If you were using the newarcs option in the last month, you need to rerun gnssir and any downstream codes (subdaily, daily_avg etc). This bug has no impact on the data translation codes (rinex2snr, nmea2snr).

GNSS-IR was developed with funding from NSF (ATM 0740515, EAR 0948957, AGS 0935725, EAR 1144221, AGS 1449554) and
NASA (NNX12AK21G and NNX13AF43G). gnssrefl was initially developed
as a fun post-retirement project, followed by support from NASA (80NSSC20K1731).
