Product overview
Shenzhen JND Technology Co., Ltd's JND ST-26-M3GL is a single-frequency, dual-mode GNSS engine module built around the AG3331 chipset. It accepts GNSS signals through an antenna input and delivers position, velocity and time messages over a serial interface using an NMEA-0183-compliant or custom protocol. Supported satellite systems include GPS, BDS, GLONASS and Galileo, together with SBAS services WAAS, EGNOS, MSAS and GAGAN. Its receiver front end incorporates a high-gain low-noise amplifier and is described as having low insertion loss.
The module measures 16x12x2.4mm and uses a surface-mount package with castellated holes, providing a compact component for integration into portable equipment. Stated integration examples include personal navigation devices, mobile phones, cameras and vehicle navigation systems. Its electrical requirements are 3.3V operation and a maximum current consumption of 35mA at that voltage, with an operating temperature range of -40 to 85°C. Sensitivity is specified as -165dBm; fast acquisition at low signal levels is described without a numerical time-to-first-fix specification.
