Gpsuinet Setup

The most common mistake in GPSUINet setup is poor antenna placement. Unlike a car GPS, the GPSUINet antenna locks onto multiple satellites simultaneously for network timing.

Determine baud rate and protocol. Common default: 4800 or 9600 baud, NMEA0183 sentences. Some modern receivers use 115200 or binary protocols—consult your GPS manual.

Test with a terminal or cat:

Ensure the GPS works by reading raw NMEA:

Linux:

cat /dev/ttyUSB0

You should see $GPGGA, $GPRMC, etc.

Windows (PuTTY or Termite): Open COM3 at 4800 or 9600 baud (common GPS rates).

In modern navigation and telemetry systems, the ability to stream GPS data over a network is essential. GPSUINet (often stylized as GPS/UINet or GPS over IP Network) refers to the process of sharing a GPS receiver’s data — typically NMEA 0183 sentences — across a local or wide area network using TCP/IP or UDP protocols. This guide provides a comprehensive walkthrough for setting up GPSUINet on Windows, Linux, and embedded platforms. gpsuinet setup

The software architecture requires two main tasks:

Allow the chosen port (e.g., 5000) through the firewall:

Linux (ufw):

sudo ufw allow 5000/tcp

Windows Defender:

Check that clients receive live NMEA sentences. On the server, monitor connections:

Linux:

ss -tulpn | grep 5000

Windows: Use netstat -an | findstr 5000

The first step in setting up a GPSUINET system is selecting the appropriate hardware. This typically involves:
