SparkFun RTK Express Plus (GPS-18590)
he SparkFun RTK Express Plus is an easy to use GNSS receiver for centimeter-level positioning. Perfect for surveying, autonomous vehicles, logging, and all types of post processing, this preprogrammed device can also be used for autonomous driving, navigation, asset tracking and any other application where there is a clear view of the sky. The RTK Express Plus adds an internal IMU to combine real-time GNSS tracking with advanced sensor fusion. The result is accurate positioning even when GNSS is lost in tunnels, parking garages, etc. Out of the box an RTK Express Plus can be used with a correction source to create an RTK system capable of 14mm horizontal positional accuracy. The built-in Bluetooth® connection via an ESP32 WROOM enables the user to use the RTK Express Plus with their choice of GIS application on a phone or tablet. The built in battery allows for over five hours of field use and is compatible with common USB battery banks.
