Introduction

Full System Multi-frequency High-precision Timing Module

ER-GNSS-M03 is a new generation GNSS full system multi-frequency, high-precision timing module. The module integrates filters, linear amplifiers, and at the same time has optimized RF structure and interference suppression capability. The internal integration of Jam Shield adaptive anti-interference technology and U-Auto Align multi-path suppression technology supports interference detection and deception detection functions, ensuring that the module can still provide good performance in complex electromagnetic environments. The module can provide nanosecond PPS accuracy, support fixed point timing, independent optimization timing, positioning timing, and still ensure good timing accuracy in complex signal environment.
