Founded in 2014, the company has established itself as a significant player in the professional surveying, mapping, and geospatial industries. With headquarters in China and operations spanning multiple continents, Tersus GNSS focuses on delivering cost-effective, reliable, and innovative GNSS receivers and solutions for professional applications including land surveying, construction, agriculture, and industrial positioning.
Company History and Development
Tersus GNSS was established in 2014 with a mission to democratize access to high-precision GNSS technology for professional users worldwide. The company emerged during a period of rapid technological advancement in satellite positioning systems, capitalizing on improvements in multi-constellation GNSS positioning and the maturation of real-time kinematic (RTK) positioning methodologies.
Since its inception, Tersus GNSS has focused on research and development initiatives to create innovative solutions that address specific market needs. The company's growth trajectory reflects increasing global demand for accurate positioning systems in surveying and construction sectors. Over the years, Tersus GNSS has invested substantially in technology development, establishing engineering teams across multiple locations to support product innovation and customer service.
Core Technologies
Multi-Constellation GNSS Reception
Tersus GNSS receivers are engineered to track signals from multiple satellite navigation systems simultaneously, including:
- GPS (United States) - GLONASS (Russia) - Galileo (European Union) - BeiDou (China) - QZSS (Japan) - IRNSS (India)
This multi-constellation approach provides superior satellite geometry, improved positioning availability, and enhanced accuracy in challenging environments such as urban canyons, forested areas, and near tall structures.
Real-Time Kinematic Technology
RTK positioning represents a cornerstone of Tersus GNSS technology. The company's RTK implementations enable centimeter-level positioning accuracy in real-time, utilizing correction data transmitted via radio links, cellular networks, or internet connections. Their RTK engines process raw satellite observations to achieve rapid integer ambiguity resolution, which is essential for reliable centimeter-accurate positioning.
Network RTK Integration
Tersus GNSS has developed network RTK capabilities that leverage multiple reference stations to generate area-based corrections. This technology eliminates the need for single base station setups, providing more flexible and scalable positioning solutions for large-scale surveying and construction projects.
Post-Processing Solutions
Beyond real-time applications, Tersus GNSS offers post-processing software that enables high-accuracy positioning from raw GNSS observations collected during field work. These solutions are valuable for applications where real-time positioning is not necessary but maximum accuracy is required.
