Draw every cable, every switchport, and every IP address. When the setup fails at 2 AM, you will not remember which port is the Grandmaster. Label physical cables with a P-touch labeler: "GPSUINet M1 → SW Port 12."

Subject: Optimal configuration, security, and performance tuning for gpsuinet in simulation and production environments.
Because PSA increases memory usage, large batch sizes might not fit on a single GPU.
The final pillar of the gpsuinet setup best is not technical—it is administrative.
Before setup, ensure:
Installation command (Debian/Ubuntu):
sudo apt update && sudo apt install gpsd gpsd-clients socat
Best for: Load testing, development without hardware.
Generate a fake GPS stream that moves along a predefined track.
Step 1: Create a sample NMEA log file (track.nmea).
$GPRMC,123519,A,4807.038,N,01131.000,E,022.4,084.4,230394,003.1,W*6A
$GPGGA,123519,4807.038,N,01131.000,E,1,08,0.9,545.4,M,46.9,M,,*47
Step 2: Serve the file over TCP port 5000 using socat (lightweight).
socat TCP-LISTEN:5000,reuseaddr,fork OPEN:track.nmea,repeat=1,forever
Step 3: Connect a client using gpsuinet or gpspipe.
gpspipe -r -n 100 | nc server-ip 5000
Alternative: If gpsuinet is a binary, run: gpsuinet -i track.nmea -o tcp://0.0.0.0:5000
Conventional wisdom says "never update a working system." For GPSUINet, the opposite is true.

Test Your Connection: Use online speed test tools to ensure you’re getting the speeds you’re paying for. If the speeds are significantly lower, troubleshoot your setup or contact your ISP.
