Product overview
The Shenzhen JND Technology Co., Ltd JND J-M200 is a communications and positioning board for integration into equipment requiring satellite positioning, including UAVs. Its architecture combines 4G communications with a high-precision RTK module, an embedded RTK algorithm and SDK differential correction services. The supplied functional configuration brings communications and navigation together on the board, giving equipment developers integrated positioning processing and correction communications without requiring them to develop an RTK algorithm or separately integrate the differential CORS communications protocol.
Integration requires external power and an external antenna, with positioning information delivered over a serial connection supporting UART/TTL. Satellite reception covers BDS B1, GPS L1 C/A and GLONASS L1, using BDS+GPS or GPS+GLONASS combinations. Positioning accuracy can reach 20 cm when paired with the Qianxun Position RTK high-precision service; that service pairing is a material condition of the accuracy figure. Support for Qianxun FindNow and A-GNSS accelerated positioning complements applications such as surveying, vehicle tracking, portable positioning equipment and IoT systems.
