Geodex NET20 Plus
High-Performance 1408-Channel GNSS Infrastructure Receiver
The Geodex NET20 Plus is an advanced 1408-channel GNSS reference receiver engineered for continuous operating reference stations (CORS). Combining full-constellation tracking with an integrated 13,600 mAh battery backup and remote FRP Web UI management, it delivers uninterrupted, millimeter-level differential positioning.
Continuous Reference Base Station with Remote Control
The Geodex NET20 Plus is engineered from the ground up for unattended 24/7 CORS networks. Featuring a high-efficiency Linux + A8 processor architecture and an intuitive Web UI, station managers can modify configuration parameters, check receiver health, and set up automatic FTP data pushes remotely without visiting field sites.
FRP Remote Tunneling
Operate Web UI through FRP settings across private networks without public IPs.
FTP / SFTP Auto-Push
Automatically stream multi-rate raw RINEX data directly to server backends.
Intuitive Web UI Dashboard for Real-Time Satellite Tracking and Port Diagnostics
Engineered for Uncompromising Reliability
Full Constellation Tracking
1408 channels track all current and future GNSS signals including GPS, BDS, GLONASS, GALILEO, QZSS, SBAS, and L-Band PPP.
