simpleRTK 4 Dual RTK Heading Starter Kit

Introduction

The ArduSimple simpleRTK 4 Dual RTK Heading Starter Kit is a high-precision GNSS evaluation platform designed for projects that need both accurate positioning and reliable orientation data. Built around the u-blox ZED-X20D dual-antenna receiver, it delivers centimeter-level RTK positioning along with real-time heading, pitch, roll, and yaw measurements.

Part Description

The AS-STARTKIT-DUAL-X20D-00 combines a dual-antenna GNSS receiver setup with two ANN-MB2 antennas for moving-baseline heading applications. Unlike compass-based heading systems, the dual-GNSS approach determines orientation from the physical baseline between the antennas. This provides stable heading information without magnetic interference, repeated calibration, or accumulated drift.

The kit supports all-band GNSS reception and can use RTK correction data to achieve centimeter-level positional accuracy. Its interfaces include USB, UART, and XBee connectivity, allowing it to integrate with computers, embedded controllers, wireless radios, and development platforms.

Compatibility with Arduino, Raspberry Pi, ROS, Pixhawk, and ArduPilot makes the starter kit suitable for prototyping, testing, and deployment in autonomous navigation systems. It is particularly useful where accurate vehicle direction must be maintained while stationary or moving slowly, conditions that can challenge conventional GNSS course-over-ground heading methods.
