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

Add this Ground Station module to your ground station computer to unlock Real-Time Kinematic (RTK) technology for centimeter location accuracy horizontally and vertically.

Alta X with F9P GPS installed (not compatible with Here2 GPS).

RTK Overview
RTK technology uses a pair of modules to increase positional accuracy. One module is installed on the aircraft (this module is called the “Rover") and the other will mount on a tripod and be connected to your ground station computer (the “Ground Station” module).

The Ground Station module will let your ground station computer send GPS corrections to the Rover module (on the aircraft) that increase precision from a few meters to a few centimeters, in real-time.

Application
This kit comes with one module, magnetic mounting hardware for common tripods (1/4" 20), and a USB cable. Here's what you will need if you have:

1. An Alta X with F9P GPS (not Here2) and you want full RTK capability:

One RTK GPS Ground Station for your ground station computer
A radio to communicate between the ground station computer and the Alta (FRX Pro, etc)
A tripod or something sturdy to mount your Ground Station module to with the included magnetic adapter

2. An Alta X with Here2 GPS, and you want fully RTK capability:

Two RTK GPS Ground Stations (one GPS module functions for your Rover and one for the ground station computer)
A radio to communicate between the ground station computer and the Alta (FRX Pro, etc)
A tripod or something sturdy to mount your Ground Station module to with the included magnetic adapter

3. An Alta X with Here2 GPS, and you just want increased GPS performance:

One RTK GPS Ground Station for your Alta X

4. An Astro Base Kit, and you want full RTK capability:

One RTK GPS Ground Station for your ground station computer
A tripod or something sturdy to mount your Ground Station module to with the included magnetic adapter

Notes

If your computer (MacBook Pro, etc) does not have USB A ports, you will need a USB A-C adapter or your own USB C-C cable.
