The David30 series provides a compact, ruggedized solution for those requiring centimeter-level precision and flexible integration. Whether you are establishing a permanent site reference station or building an autonomous navigation system, these receivers provide professional results in an affordable, palm-sized package.
Supports:
Full Multi-Constellation GNSS Coverage
Supports BeiDou, GPS, GLONASS, Galileo, and QZSS for global positioning reliability.
High-Capacity Channel Architecture
576 David30 / 1408 David30-D channels for fast acquisition and stable tracking.
RTCM v2.x & v3.x Correction Support
Ensures high-precision positioning across correction networks.
Built for Seamless System Integration
Flexible design for easy integration into a wide range of applications.
High-Speed Position Updates
Delivers data update rates of up to 20Hz for real-time performance.
Rugged IP67 Environmental Protection
Dust-tight and waterproof enclosure for dependable operation in harsh field conditions.
PPP Correction Service Compatibility
Available with TAP PPP correction services for enhanced positioning accuracy.
Wide Software Compatibility
Works with Tersus Nuwa and third-party applications using NMEA-0183.
Small Footprint. Serious Precision. Built to Scale.
The Ideal Permanent Base Station
Stop overpaying for your CORS or local base setups. The David30 offers the same multi-constellation, 1408-channel tracking as expensive competitors in a rugged, IP67-rated enclosure. It’s a “set it and forget it” solution for broadcasting stable, reliable corrections across your network.
Affordable PPK for Drone Missions
Maximize your drone mapping accuracy without the price tag of an onboard RTK system. The David30 captures high-quality raw RINEX files to internal storage, making it the most cost-effective solution for post-processed (PPK) workflows.
Seamless Custom Integration
Need precise positioning and heading for a robot, autonomous vehicle, or custom sensor? The David30’s palm-sized form factor and wide power input (5–28V) make it the easiest way to add centimeter-accurate GNSS to any third-party application.

Built In-House by Tersus.
Built to Perform for You.
At Tersus, building “just another RTK system” is never the goal. Tersus designs and develops its own GNSS boards and core RTK technologies, building solutions from the ground up rather than relying on generic, off-the-shelf components. It’s a simple belief that guides every receiver we’ve built: build better, or don’t build at all. Every receiver delivers high-performance, centimeter-level RTK accuracy without unnecessary cost, providing reliability and precision in even the toughest environments.
