Product overview
The Shenzhen JND Technology Co., Ltd ST-91-M10F provides satellite positioning, tracking and navigation for integration into electronic equipment. Its intended applications include flight-control models, UAVs, four- and six-rotor aircraft, and other multirotors, alongside portable devices, vehicle equipment, surveying instruments and tracking systems. The hardware is a single-frequency, multi-constellation receiver module built around the tenth-generation u-blox M10050. Its physical architecture uses single-sided surface mounting with a secondary SMT assembly approach, while the integrated receiver components include an LNA, SAW filter and flash.
Integration options include configurable NMEA 0183 V4.1 sentence combinations, a default data output rate of 9600bps and selectable alternatives extending to 921600bps. The data refresh rate is adjustable from 1Hz to 10Hz. User settings cover pedestrian, automotive, static, portable and airborne operation, plus 2D or 3D positioning. A KDS 0.5PPM TCXO and built-in RTC crystal support the receiver architecture. AssistNow Online and Offline support assisted positioning, while the positioning PPS indicator can remain lit or off before a fix and flash after a fix.
