gpssnrpy 0.0.2

A GPS/SNR translation software package1

gpssnrpy

This library will allow python users easy access to RINEX translators currently only provided in Fortran (gpsSNR.f and gnssSNR.f). This first version is a port of gpsSNR.f.

to install

• git clone https://github.com/kristinemlarson/gpssnrpy

• cd into gpssnrpy, set up a virtual environment and activate it.

• pip install .

to run from the commandline

Inputs:

• RINEX v2.11 observation filename
• output filename
• RINEX v2.11 navigation filename
• SNR choice (99, 66, 88, 50) as defined at the gnssrefl website

Optional

• -dec decimation (seconds)

Thus this translates and decimates to 30 seconds:

• gpssnr rinexname outputname navname 99 -dec 30

or translates it all:

• gpssnr rinexname outputname navname 99

I have provided a small obs file (and nav file) you can use to test the code:

• gpssnr p1011500.20o p1011500.snr auto1500.20n 99 -dec 30

I am still working on this documentation

Thank you to the developers of numpy for providing excellent documentation for f2py and raxod502 for his package management help!
