Overview

TerraStar Correction Services, provided by NovAtel, offer high-precision GNSS correction data in real-time, ensuring minimal latency. These services are transmitted directly to compatible NovAtel GNSS receivers via satellite link or internet connection, delivering robust and reliable positioning solutions globally. With over 20 years of GNSS expertise, TerraStar services are designed to meet the precise positioning needs of various applications, including precision agriculture, construction, surveying, UAVs, and ground truth systems.

Features and Capabilities

• Global Coverage: TerraStar services provide complete worldwide coverage, supported by a network of over 90 independently owned and operated GNSS reference stations.
• High Accuracy: Achieve sub-meter to centimeter-level positioning accuracy, with services like TerraStar-X delivering 2.5 cm horizontal accuracy and 5 cm vertical accuracy, converging in under a minute.
• Multiple Service Levels: TerraStar offers various service tiers, including TerraStar-X, TerraStar-C PRO, TerraStar-C, TerraStar-L, and RTK ASSIST, allowing users to select the service that best fits their accuracy and convergence time requirements.
• Reliable Data Transmission: Corrections are delivered through five geostationary communication satellites, ensuring overlapping global coverage and redundancy. Corrections are transmitted over a minimum of two beams (parallel L-band tracking) directly to end-users, ensuring continuous availability of correction data.
• Robust System Architecture: The system includes three geographically separated Network Control Centers, contributing to over 99.999% service availability. Ownership over the end-to-end correction generation process ensures industry-leading data quality.
• Fast Convergence Times: Services like TerraStar-X offer convergence to 2 cm accuracy in under a minute, providing rapid initialization for precise applications.
• Multi-Constellation Support: TerraStar corrections support multiple GNSS constellations, including GPS, GLONASS, Galileo, and BeiDou, enhancing positioning reliability and accuracy.
• Seamless Integration: Designed for compatibility with NovAtel's OEM6 and OEM7 receivers, enabling easy integration into existing systems.
