Introduction

ER-GNSS/MINS-07 Low Cost Single Antenna MEMS Integrated Navigation System

Introduction
ER-GNSS/MINS-07 is equipped with a highly reliable MEMS IMU and integrates a single-antenna full-system dual-frequency positioning satellite module. It is a low-cost single-antenna integrated navigation system.
Equipped with a integrated navigation fusion algorithm, it can provide continuous, accurate and reliable positioning, attitude, and speed information, with attitude up to 0.1° and heading 0.1°.
It uses a low-cost MEMS inertial measurement unit (IMU), internally integrated with a three-axis MEMS gyroscope and accelerometer, and a -40℃~+80℃ full-temperature range temperature compensation algorithm, which greatly reduces costs while ensuring core performance.
Different from the complex structure and cost of traditional dual-antenna solutions, ER-GNSS/MINS-07 adopts a single-antenna full-system dual-frequency design to achieve high-precision positioning and speed measurement.
The precision aluminum alloy shell has high reliability and adapts to harsh environments. It has a variety of communication interfaces and provides standardized user communication protocols to meet aviation, land and other applications.
