Product Details

ER440 High-Precision RTK Positioning Module


Introduction

ER440 High-Precision RTK Positioning Module adopts the new generation full system full frequency point 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-wide satellite signals and anti-jamming processing. Through the enhanced RTK engine calculation, the advantages of multiple systems are fully utilized, and high-performance, high-reliability centimeter-level accuracy is achieved on the basis of low-power and low-cost solutions. The positioning performance is significantly superior. Other single-frequency RTK products on the market. ER440 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 shades. Positioning results.
