Installation

First, find the LEOGPS GitHub repository in this GitHub link, and download it. Alternatively, if you have Git installed, you can open Command Prompt or your Git Bash, enter the directory of your choice, and type:

git clone https://github.com/sammmlow/LEOGPS.git

Second, you should do a pip install in your terminal of Martin Valgur’s Pythonic translation of Hatanaka (de)compression in Python:

pip install hatanaka

The Hatanaka library in Python was kindly contributed by Martin Valgur in v1.1, and replaces the older “RNX2CRX” and “GZIP” Windows-only executables, making the (de)compression possible across all operating systems.

That’s it! No further setup is needed, unless you need any of the other package dependencies.

Note

Package dependencies include: copy, datetime, decimal, hatanaka, math, matplotlib, numpy, os, pathlib, PIL, tkinter, unlzw3, urllib, warnings

Next, we will run and explain the setup behind the default native scenario packaged in LEOGPS - a formation flying scenario at ~200km in-track baseline of the GRACE mission.
