The RTK Express Plus Kit has everything you need to get centimeter level global positioning measurements using GNSS RTK. We've created a handy carrying case to protect the most expensive bits, allowing you to quickly attach the L1/L2 antenna and RTK Express Plus housing to the pole or tripod of your choice. The kit includes all the antenna bits, cables and chargers you need to jump right into the field.
The RTK Express Plus is a Bluetooth enabled multi-band GNSS receiver with built-in IMU based on the ESP32 from Espressif and the ZED-F9R from u-blox. Power it up and you'll have 300mm approximate accuracy out of the box and 14mm accuracy with RTCM corrections. This kit provides the L1/L2 antenna, adapters, interface cables, and chargers needed for general GNSS use.
The RTK Express Plus adds an internal IMU (ZED-F9R) to combine real-time GNSS tracking with advanced sensor fusion. The result is accurate automotive positioning even when GNSS is lost in tunnels, parking garages, etc. The downside is the ZED-F9R does not support base station or generating RTCM corrections. If you are implementing your own RTK base station, consider using products based on the ZED-F9P. The IMU algorithms only apply to automotive applications and will not increase or decrease regular 'clear view of the sky' positioning performance.
