Tersus GNSS Inc. has released a major upgrade to its Precis-BX306 RTK board with new and improved GPS/GLONASS functionality. Tersus GNSS is a manufacturer of high-precision GNSS real-time kinematic (RTK) boards, receivers and systems. Precis-BX306 Board Easy Kit. The new version of Precis-BX306 supports up to 20-Hz RTK solution and raw measurement output, which can be integrated with autopilots and inertial navigation units. With improved algorithms, the new Precis-BX306 demonstrates its ability that the 30-km baseline can be fixed quickly, the company said. Moreover, the dynamic fix rate shows an advantage comparing to the majority of competitive solutions. Stable fix rate is achieved when it is working under city valley, tree, and other challenging environment. “The technology changes made in this version give a whole new user experience for our customers,” said Xiaohua Wen, founder and CEO. “With the updated capabilities, the Precis-BX306 is particularly useful for drones, surveyors and geographic information system data users interested in an affordable RTK solution.” This latest version of Precis-BX306 is pin-to-pin compatible with major GNSS boards in the market, offering a flexible interface. Event mark and PPS are supported as always. All enhanced features demonstrate Tersus’ commitment to the needs of customers who value dynamic accuracy and stability. The new Precis-BX306 is available for order and delivery immediately, and it will be shown at Intergeo in Berlin, Germany, Sept. 26-28.
