The TSA520 is a high-performance external survey GNSS antenna engineered for professional-grade precision. It provides comprehensive, full-frequency compatibility with all major global navigation systems, including GPS, GLONASS, BDS, and GALILEO, ensuring reliable performance worldwide. This multi-system support makes it a versatile and indispensable tool for a vast array of high-accuracy applications. It is ideally suited for critical projects in geodetic and cadastral surveying, marine and hydrographic measurement, as well as continuous structural and environmental monitoring tasks such as bridge and landslide deformation analysis, seismic activity tracking, and port container operations.
The cornerstone of the TSA520’s performance is its exceptional phase center stability, achieved through an innovative multi-point feeding design. This technology minimizes measurement errors and is fundamental to delivering consistent, millimeter-level positioning accuracy, which is validated by its successful passing of the rigorous international NGS certificate test. Furthermore, the antenna excels in challenging environments. Its ability to track low-elevation satellites with high gain and a wide beam width ensures continuous, reliable signal acquisition and positioning solutions even in obstructed areas like urban canyons, under foliage, or on autonomous vehicles and agricultural machinery.
Built for resilience, the TSA520 features a robust IP67-rated enclosure, offering complete protection against dust and water ingress for dependable operation in the harshest field conditions. Its compact design, with a weight of ≤400g, minimizes load on platforms like small UAVs and robotic systems, facilitating easy integration via a standard TNC female connector. Complementing its durability is a strong anti-interference capability. The integrated Low-Noise Amplifier (LNA) with excellent out-of-band rejection suppresses electromagnetic interference (EMI), ensuring GNSS signal stability and reliability even in complex environments like areas near communication base stations.
Defined by its professional-grade specifications, the TSA520 guarantees operational excellence. It supports an extensive signal suite encompassing QZSS, SBAS, and NavIC (IRNSS) across multiple frequency bands. Key LNA features include a gain of 34±2dB (L1) and 36±2dB (L2), a low noise figure of ≤2dB, and a wide operating voltage range from +3.3V to +12V DC. Mechanically, it is designed to withstand extreme temperatures from -40°C to +85°C. This combination of advanced performance, rugged IP67 construction, and reliable connectivity establishes the TSA520 as a trusted, high-precision geodetic antenna for global surveying professionals.
