Product Details

K708 Full System Full Frequency Single Antenna High Precision GNSS Positioning Board

The K708 GNSS motherboard is a four system OEM motherboard developed by Sinan Navigation based on independent intellectual property ASIC chips. It adopts the Beidou three frequency ultra long distance and ultra fast high dynamic calculation engine, and can achieve decimeter level positioning accuracy in a single epoch of 100 kilometers. The hardware size, interface, and data instructions of K708 are compatible with imported motherboards.

K708 can be widely used for high-precision differential positioning and timing in industries such as multi system reference stations, high-precision surveying, aerospace, deformation monitoring, mechanical control, system integration, precision agriculture, exploration, transportation, oceanography, ports, meteorology, national defense, scientific research, and universities.
