Description

ArduSimple simpleRTK 4 Dual – RTK Heading Starter Kit is a ready to use evaluation kit including a dual antenna GPS/RTK receiver and two high performance GPS/RTK antennas.

With antennas placed at 1 meter distance, the kit is able to calculate out of the box the true north / heading, with an accuracy of 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 all-band 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.

Known limitations:
– This is a very new chip from u-blox, regular firmware upgrades are to be expected during the coming months.
– April firmware will only support correction data from static base station via USB and JST (UART1).
– XBee socket (UART2) static base station corrections will be available in June firmware upgrade.

Includes:
– 1 simpleRTK 4 Dual board (ZED-X20D)
– 2 u-blox ANN-MB2-00 Tripleband GNSS antenna
