simpleRTK3B Heading

Description

simpleRTK3B Heading is a standalone board designed to evaluate dual-band RTK GNSS technology, delivering centimeter-level positioning accuracy along with heading and microSD datalogging capabilities. Built around the Septentrio mosaic-H module, it can operate independently or as a shield for platforms such as Arduino, Raspberry Pi, Nvidia Jetson Nano, and STM32 Nucleo. This allows for up to 20 RTK positions and attitude (heading) measurements per second. This board is particularly suited for advanced projects utilizing the Pixhawk autopilot.

Key Points:

• It includes a native microSD card datalogger, but the microSD card is not included.
• Compatibility is assured, but two multiband GNSS antennas are required for operation.
• Standard GNSS antennas will not yield optimal performance; an L1/L2/E5b antenna is recommended.
• This board is recommended for evaluating the performance of the Septentrio mosaic-H module.
• Configured primarily as a Rover, it can also be utilized as a Base Station.
• It is compatible with the entire range of Ardusimple XBee socket accessories, including 4G modems, MR/LR/XLR radios, Bluetooth, WiFi, Ethernet, dataloggers, and RS232 interfaces.
• It is also compatible with Ardusimple's plastic case for additional protection.
• It is Ardupilot compatible via a JST-GH standard connector, facilitating easy integration.
• Product Codes:

1. AS-RTK3B-MH-L1L2-NH-00
2. AS-RTK3B-MH-L1L2-HS-00
