How to replace your correction service with a RoboDot

There are a number of Virtual Reference Station (VRS) services that send correction messages to RTK enabled rovers or drones via the internet. These correction servers come in handy; users don't need to own expensive base station equipment or set up the base station on known coordinates.

While convenient and easy to use, VRS services have some pitfalls and inconveniences:

  • Internet connectivity may be unavailable or unreliable

  • VRS service areas are limited

  • Monthly subscription costs add up

RoboDot solves all of these problems while keeping setup simple. Operating as a local RTK base station, RoboDot provides correction services within a 20 km operating radius, and does not require internet connectivity. With RoboDot you still get the simplicity of connecting to a VRS but without the related subscription costs.

Here's how


First, arrive at your project site. Locate a reference point or set up a new one. Optionally paint a ground control marker where you will place the RoboDot (we provide the stencil). The mark lets you come back to that exact point later.

If the coordinate of the reference point is known, connect to the RoboDot Wifi with a laptop or cellphone, then navigate to In the status page set the base coordinate.
