simpleRTK 4 Dual
First dual antenna GPS board with u-blox ZED-X20D, for centimeter precision and out-of-the-box moving baseline (heading, orientation, north indicator, compass, roll, pitch, yaw).
This product will ship on April 20th 2026.
This product comes with 2 years worldwide warranty
simpleRTK 4 Dual is a standalone board that allows to evaluate triple band RTK GNSS technology including centimeter level accurate position and sub degree heading.
It’s based on u-blox ZED-X20D module and can be used standalone. Or connected with Arduino, Ardupilot / Pixhawk (JST connector), Raspberry Pi, Nvidia Jetson and STM32 Nucleo platforms, as a shield, to provide you up to 25 RTK positions and attitude (heading) every second.
simpleRTK 4 Dual is ideal for upgrading your ZED-F9P moving base project. With dual antenna already integrated inside the product, it’s more reliable and at lower cost.
More details available in the Specification and Documentation tabs.
Good to know:
– This product is compatible but doesn’t include a multiband GNSS antenna, of which 2 are necessary to use the product.
– This board is recommended if you want to test u-blox ZED-X20D performance.
– The onboard XBee socket can be used to expand functionality with Plugin accessories (MR/LR/XLR radios, Bluetooth, WiFi, Ethernet, Dataloggers, RS232, Canbus, 4G/3G/2G).
– The ZED-X20D can’t be used as base station, only works as RTK Rover.
– You can use the Shield for Second Plugin socket to connect 2 plugins at the same time.
– Compatible with Ardusimple plastic case
