gpsd

gpsd is a handy service daemon that helps manage access to GPS sensors, whether they’re connected via serial ports or USB. The cool part? It lets multiple applications get GPS info without stepping on each other's toes!

How Does gpsd Work?

Basically, gpsd keeps an eye on one or more GPS devices hooked up to your computer. It does this through those serial or USB ports we mentioned earlier. All the information about your location, course, and speed gets made available through TCP port 2947 on the host computer. So, it’s super easy for different programs to grab the data they need!

Why Use gpsd?

If you’ve got several GPS client apps—like navigation tools or wardriving software—gpsd lets them all share access to the same GPS device without losing any data. Plus, it responds with data in a format that’s much easier to work with compared to the usual NMEA 0183 format that most GPS devices spit out.

Developer-Friendly Tools

The gpsd package comes with some great extras for developers too! It includes a C service library you can link into your projects, along with a C++ wrapper class and even a Python module. These tools make it simple for anyone building gpsd-aware apps to handle all communications with gpsd.

A Few Extra Features

Apart from the main features of gpsd, there are also helpful auxiliary tools included in the project. These are perfect for profiling and monitoring your GPS devices and can even help feed logs to GPS-aware applications for troubleshooting.
