GPS "Classic" M9N w/IST8308 - M10034 hwrev

img

Features the latest Taoglass Antenna tuned for GPS + GLONASS + Galileo constellations, which provide a higher gain compared to any of its predecessors (from 1.5dBi to 5dBi). iSentek IST8308 is a 3-axis digital magnetometer is an integrated chip with 3-axis magnetic sensors, digital control logic, built-in temperature compensation circuit and self-test function. IST8308 provides an I2C digital output with fast mode up to 400kHz. The high output data rate, ultra-low noise, ultra-low hysteresis and excellent temperature drift features make it a perfect candidate for high accuracy applications.

Module: NEO-M9N The NEO-M9N module is built on the robust u-blox M9 GNSS chip, which provides exceptional sensitivity and acquisition times for all L1 GNSS systems. The u-blox M9 standard precision GNSS platform, which delivers meter-level accuracy, succeeds the well-known u-blox M8 product range. NEO-M9N supports concurrent reception of four GNSS. The high number of visible satellites enables the receiver to select the best signals. This maximizes the position accuracy, in particular under challenging conditions such as in deep urban canyons
