The JS-M6D is a compact, multi-frequency, multi-mode RTK high-precision positioning module that supports six frequency points: BDS B1I+B2I, GPS/QZSS L1+L2, and GLONASS G1+G2. Designed with an LGA package, it is compatible with standard pick-and-place and reflow soldering processes, making integration simple and efficient. With high sensitivity, strong anti-interference, and outstanding performance, the JS-M6D delivers reliable and precise positioning for demanding applications.
