3.3 Clone & Build GPSUINet Core

git clone https://github.com/your-repo/gpsuinet.git
cd gpsuinet
mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make -j$(nproc)
sudo make install

4. Deployment Optimizations (“Best” for Inference)

11. Backup & Recovery

Backup these directories daily:

• /etc/gpsuinet/
• /var/lib/gpsuinet/rinex/
• /var/log/gpsuinet/

3.2 Set Up NTP for Accurate Timestamps

sudo timedatectl set-timezone UTC
sudo systemctl enable ntp
sudo systemctl start ntp
ntpq -p   # Verify peers

The Health Dashboard

Your GPSUINet software should display:

• DOP (Dilution of Precision): Target < 1.5. If > 2.0, your antenna placement is bad.
• Time Offset: Should be ±100 nanoseconds. If you see microseconds, check your PTP sync interval.
• Jitter: Measured in milliseconds. Steady jitter is fine; erratic jitter indicates a faulty switch port.

The "GPSUINet Setup Best" Checklist (Executive Summary)

To save you from scrolling back up, here is your quick-hit checklist: gpsuinet setup best

| Component | Best Practice Setting | | :--- | :--- | | Antenna | Dual-band, clear sky, <30m cable, surge protected | | Switch | IEEE 1588v2, Transparent Clock mode, Industrial grade | | PoE | 802.3bt (60W per port) | | IP Strategy | Static IPs (10.10.10.x/24) | | Timing | Sync interval 125ms, Domain 24, E2E delay | | QoS | DSCP 46 (Expedited Forwarding) | | VLAN | Dedicated ID 999, isolated from data traffic | | Redundancy | Dual Grandmasters, RSTP ring topology, Pure sine UPS | | Monitoring | Check DOP < 1.5, Time offset ±100ns daily |

4. Hardware Setup (Receivers)

Connect GNSS receivers via USB or serial. Verify with: Report Title: Comprehensive Guide to Optimal GPS-U-Net Setup

ls -l /dev/ttyUSB*   # USB receivers
ls -l /dev/ttyACM*   # Embedded receivers
