Photo: Tersus GNSS Tersus GNSS Inc. has released the BX40C RTK board to support its series of GNSS boards and provide highly accurate and fast positioning services. Powered by the company’s new ExtremeRTK GNSS technology, the BX40C board can support multi-constellation and multi-frequency all-in-view satellite tracking. The Tersus BX40C is a compact GNSS real-time kinematic (RTK) board with full constellation tracking for providing centimeter-level accuracy positioning. It can be integrated with autopilots and inertial navigation units to meet various developing requirements. It is suitable for high-precision positioning, navigation and mapping. “Tersus has been proud of its BX-series RTK boards, and today we added a new member to the series by launching the new BX40C board,” said Xiaohua Wen, founder and CEO of Tersus GNSS. “The BX40C is with enhanced positioning accuracy and constellation tracking, even in harsh environments, the BX40C board can still control deviation within 3-centimeter in surveying and mapping applications. It supports 576 channels and can achieve centimeter-level position accuracy easily. We are excited to see how BX40C strengthens our product portfolio and technology competence to make a great effort in this industry.” The BX40C board supports multiple constellations and frequencies to improve the continuity and reliability of the RTK solution — even in harsh environments. In-built 4GB memory makes data collection easy, the company said. It is compatible with other GNSS boards in the market via flexible interfaces, smart hardware design and commonly used log/command formats.
