Faking Geolocation (POSTGIS) For Django Project

Anyone know of a method or package that can “stand-in” for true POSTGIS Geolocation? I want to develop the core of an app on my Windows machine, then fill in the GEO portion using my VM Ubuntu. I have tried for years to get GEO on Windows to install and work correctly, while using Ubuntu or other Nix OS seems to have few issues. However, I’m more at home on the Win machine, have multiple large screens and was wondering if anyone came across this before.
Ultimately, I’ll do the dev on my Ubuntu machine - just thought I’d ask to see if someone went down such a route before and has any advice. Thanks
