TSA320

The TSA320 is a high-performance external survey GNSS antenna designed to deliver reliable, precise positioning for professional applications. It provides comprehensive four-system, full-frequency coverage, supporting GPS, GLONASS, BDS, and GALILEO signals, thereby meeting the essential multi-system compatibility requirements of modern measurement. This versatility makes it an indispensable tool across a wide spectrum of industries. Professionals utilize the TSA320 for critical tasks in geodetic and land surveying, marine and hydrographic measurements, as well as continuous monitoring projects such as seismic activity, bridge and landslide deformation analysis, and port container operations, where accuracy and reliability are paramount.

 

The antenna’s outstanding performance is anchored in its high phase center stability, achieved through an innovative multi-point feeding design. This is fundamental to ensuring millimeter-level positioning accuracy and providing superior RTK solutions, a claim validated by its successful passing of the international NGS certificate test. Furthermore, the TSA320 excels in challenging environments. Its ability to track low-elevation satellites with high gain and a wide beam width ensures continuous and reliable operation under obstructed skies. Coupled with strong anti-interference performance that suppresses electromagnetic noise, it guarantees signal stability even near communication base stations or in busy urban areas.

 

Engineered for durability and seamless field integration, the TSA320 features a rugged IP67-rated enclosure. This offers complete protection against dust and water ingress, ensuring reliable performance in the harshest outdoor conditions. Its compact and lightweight design, weighing ≤450 grams, minimizes the load on various platforms, making it an ideal choice for integration onto small unmanned aerial vehicles (UAVs), autonomous vehicles, and agricultural machinery. The standard TNC female connector facilitates easy and robust connection, blending portability with the resilience required for demanding surveying and mapping applications.

 

The TSA320 is defined by professional-grade specifications that ensure operational excellence. It supports an extensive signal suite including 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 built to withstand extreme temperatures from -40°C to +85°C. With its proven accuracy, robust construction, and global signal compatibility, the TSA320 stands as a trusted and versatile geodetic antenna for high-precision positioning tasks worldwide.
