Product Details

ER442 High-precision RTK Positioning And Orientation Module


Introduction

ER442 High-precision RTK Positioning And Orientation Module uses a new generation of full-system full-frequency high-precision SoC chip—Nebulas-II, which supports 432 super channels. Its powerful processing capability and embedded JamShield anti-interference technology can simultaneously track BDS, GPS, GLONASS, Galileo, and SBAS. , QZSS and other system satellite signals, and anti-jamming processing. Through the calculation with Xingtong's enhanced RTK engine, it takes full advantage of multiple systems to achieve high-performance, high-reliability centimeter-level positioning accuracy and high-precision orientation based on low power consumption and low cost solutions. Using Instant Heading technology, real-time dynamic high-precision fast orientation of mobile base stations with variable baseline length is achieved. ER442 integrates the on-board MEMS chip and U-Fusion integrated navigation algorithm, which effectively solves the situation where the positioning results are interrupted due to the loss of satellite signals. It can provide continuous high quality in complex environments such as buildings, tunnels, viaducts and shade Positioning results.
