ComNav Technology has released its advanced K700 and K708 GNSS OEM boards to the international market. K700 OEM Board With the advanced ComNav application-specific integrated circuit (ASIC) chip, K7-series OEM boards have higher observation data quality and lower power consumption compared to previous K5-series OEM boards. The data output rate also increases substantially by working with a new Atmel processor. As a cost-effective GNSS OEM board, K700 is scalable for sub-meter to centimeter-level positioning applications such as geographic information systems (GIS), precision agriculture, marine and automotive systems. It can track GPS L1, BeiDou B1, GLONASS L1 and SBAS, and also supports PPS, Event Marker and short baseline RTK. The size, weight and power specifications of the K700 make it easy to be customized and integrated, the company said. K708 OEM Board For the K708 OEM board, the inside GNSS tracking engine with 388 channels is capable of tracking all current and future constellations. K708 is designed with strong compatibility and built-in functions, including high-accurate PVT output, long baseline RTK and reserved webserver service. The 8-GB onboard memory provides sufficient storage space to record the raw data without an external memory card. Therefore, K708 OEM board is designed for CORS, deformation monitoring system and related high-accuracy GNSS positioning applications.
