Everything you need for an RTK setup. Two Piksi OEM modules and a radio link to connect them, along with two external GPS antennas.
Piksi is a low-cost, high-performance GPS receiver with Real Time Kinematics (RTK) functionality for centimeter-level relative positioning accuracy. While two Piksis are required for centimeter-level positioning, here you can buy a single Piksi OEM Module for other use cases.
This cable enables you to connect your Piksi module's 5-pin UART port to the 6-pin GPS port on 3D Robotics' Pixhawk autopilot system. Please note that Swift Navigation does not provide support for integration with Pixhawk or other companies' products.
An external GPS antenna for better satellite signal acquisition, better satellite tracking and easier system integration. NOTE: an external GPS antenna is included with each Piksi module by default.
