AZGPS FAQ Directory
GNSS Networks are revolutionizing how surveyors in Arizona and Southern California achieve accuracy, reliability, and speed in the field. By delivering Real-Time Kinematic (RTK) corrections through an internet-connected network of reference stations, they remove the need for on-site base setups — saving time, reducing complexity, and ensuring data consistency across every project.
The AZGPS GNSS Network provides continuous, secure correction coverage across Central and Southern Arizona and into Southern California. It’s a fully maintained CORS (Continuously Operating Reference Station) system designed to support surveyors, engineers, and GIS professionals who demand precise, reliable data anywhere they work.
🛰️ 1. What GNSS Networks Do
GNSS (Global Navigation Satellite System) networks use signals from GPS, GLONASS, Galileo, and BeiDou satellites. These signals are monitored by multiple fixed base stations, which send correction data to a central server. Surveyors connect their rovers or data collectors via NTRIP to receive real-time, centimeter-level corrections directly in the field.
⚖️ 2. GNSS Networks vs. Traditional Base–Rover RTK
Traditional RTK requires setting up your own base station on a known point, broadcasting corrections to your rover via UHF radio or Bluetooth.
While effective for small sites, it introduces limits — including range constraints, radio interference, and the need to reoccupy control points daily.
GNSS Network RTK eliminates those issues by providing statewide coverage with multi-base correction geometry.
This means:
- ✅ No need to set up or maintain your own base each day
- ✅ Instant corrections from the nearest reference stations
- ✅ Accuracy maintained over long distances
- ✅ Less downtime and fewer errors from signal dropouts
- ✅ Consistent results across multiple crews and regions
In short — network RTK provides the same precision as local base setups, but with more reliability, flexibility, and time savings.
📶 3. Broad Equipment Compatibility
The AZGPS GNSS Network supports all major GNSS equipment brands including Trimble, Leica, Topcon, Spectra Precision, Carlson, Hemisphere, and Emlid. If your device supports NTRIP or RTCM corrections, it can connect directly — no proprietary hardware or software required.
🌐 4. Expanding Coverage Across the Southwest
AZGPS operates an expanding network of base stations providing dense RTK coverage across Arizona and Southern California. The network’s local redundancy ensures consistent performance, even in remote or high-interference environments — ideal for boundary, construction, GIS, and infrastructure projects.
⚙️ 5. Why GNSS Networks Matter in 2025
As surveying continues to evolve, GNSS networks form the backbone of modern geospatial operations. They support not only traditional land surveys, but also UAV mapping, precision agriculture, smart construction, and autonomous equipment.
