This product will ship on April 20th 2026.
This product comes with 2 years worldwide warranty
ArduSimple simpleRTK 4 Dual – RTK Starter Kit is a ready to use evaluation kit including a dual antenna GPS/RTK receiver and two high performance GPS/RTK antennas.
Out of the box and with antennas placed at 1 meter distance, the kit is able to calculate the true north / heading, with an accuracy below 0.1 degrees. Shorter distance between antennas is possible but performance will be reduced. The kit doesn’t require calibration, and doesn’t have drift, unlike IMU- and magnetometer- based systems.
The kit is ideal to complement autopilots to get YAW information, in addition to position information.
The kit also provides position using GNSS technology, down to 1 meter of error when used standalone, and down to 1 centimeter of error when connected to a RTK base station.
This tripleband GPS kit can be used standalone connected to a PC or powerbank. And is also fully compatible with Arduino, STM32 Nucleo, Raspberry Pi, Nvidia Jetson, ROS and Pixhawk / Ardupilot.
