CORS Receivers & GNSS Antennas.
Build permanent reference stations, regional VRS networks, or deformation monitoring arrays. A 1408-channel receiver paired with IGS-certified choke ring or geodetic antennas — the infrastructure layer that makes every RTK rover accurate.
One receiver. Three antenna classes.
From a 5 kg IGS-certified choke ring for permanent CORS installations to an 18-gram compact module for UAV integration.

VNet8
1408-channel multi-constellation GNSS reference receiver for CORS and VRS networks. 64 GB storage, 12500 mAh backup battery, IP68 MIL-STD-810G ruggedization, embedded OS firewall, and unlimited concurrent correction streams. The foundation of any permanent reference infrastructure.

AT-45101CP
The gold standard for permanent CORS stations. Unique 3D choke ring design delivers sub-millimeter (≤±1 mm) phase center stability and exceptional multipath rejection across all GNSS frequencies including L-Band. Certified by IGS and NGS. Deployed in China Mobile HAP, national power grids, and provincial CORS centers.

AT-35101H
Full multi-constellation geodetic antenna at a fraction of the choke ring's size and weight. 460 g, ≤±1.8 mm phase center stability, full L-Band support. Ideal for mobile reference stations, road construction, marine surveying, and semi-permanent monitoring where portability matters without sacrificing signal quality.

AH-3232
18 grams. 27.8 mm diameter. Dual-band tracking with GPS, GLONASS, BDS, Galileo, QZSS, NavIC, and SBAS. Designed for UAVs, USVs, autonomous vehicles, robots, and precision agriculture equipment where size and weight are the primary constraint but GNSS accuracy cannot be compromised.

The foundation behind every RTK fix.
CORS receivers and GNSS antennas serve the infrastructure layer that makes centimeter-accurate fieldwork possible.
CORS / VRS Networks
Build regional or national continuously operating reference station networks serving unlimited concurrent RTK users within 30-50 km radius.
Deformation Monitoring
Sub-millimeter phase center stability for bridge deflection, building settlement, dam monitoring, and geological hazard early-warning systems.
Construction Base Stations
Semi-permanent or project-duration base stations on large construction sites, providing consistent RTK corrections to all rover crews on site.
Geodetic & Control Surveys
High-precision static observations for national geodetic networks, datum establishment, and control survey campaigns.
Marine & Hydrographic
Geodetic antennas on vessels or shore-side base stations for bathymetric surveys, port construction, and marine positioning.
UAV & Autonomous Systems
Ultra-compact AH-3232 antenna for drone PPK/RTK integration, autonomous guided vehicles, and robotic positioning platforms.
