gps-share is a utility to share your GPS device on local network. It has two goals:
Share your GPS device on the local network so that all machines in your home or office can make use of it.
Enable support for standalone (i-e not part of a cellular modem) GPS devices in Geoclue. Since Geoclue has been able to make use of network NMEA sources since 2015, gps-share works out of the box with Geoclue.
The latter means that it is a replacement for GPSD and Gypsy. While "why not GPSD?" has already been documented, Gypsy has been unmaintained for many years now. I did not feel like reviving a dead project and I really wanted to code in Rust language so I decided to create gps-share.
