Need centimeter-level accuracy for your Alta X? Freefly RTK GPS utilizes Real Time Kinematic (RTK) technology to enable pin-point location accuracy vertically and horizontally. 

Product Details

RTK technology uses a pair of modules to increase positional accuracy. One module will be installed on your Alta X (Rover), and one will be stationary on the ground, connected to your ground station computer (Ground Station). The Ground Station module sends corrections to the Rover module to enable the high-precision location information. 

This kit comes with everything you need to install the module on the Alta X, a magnetic quick-release mount to install the ground module to your existing tripod, and a 3m USB A-C cable for easy connection to your ground station computer.

You can either have us install it when you order an Alta X (look for it in the pre-built options), you can order and install it yourself on a base Alta X model, or you can install it yourself if you already have an Alta X without RTK.


  • For RTK to function, you must use Alta Ground Control (on a ground station computer) with a long-range radio telemetry link to the Alta X (such as the FRX Pro for Alta X).
  • If the Ground Station module is not active or linked with a long-range radio system, the Alta will have standard GPS accuracy.
  • Early production modules will be 3D printed (MJF) before we switch over to molded parts. This doesn't impact performance or reliability. 
  • If your computer (MacBook Pro, etc) does not have USB A ports, you will need a USB A-C adapter. 
  • Utilizes 2 RTK GPS modules (U-blox ZED-F9P); one for aircraft (“Rover”), the other for ground (“Base Station”)
