Building an RTK Base station

Standard geolocation only has an accuracy of a few meters because atmospheric disturbances (among other factors) cause errors in satellite signals.

To obtain centimeter-level accuracy, it is necessary to have a static GNSS receiver: a Base station.

It must be fixed on a stable support with a clear view of the sky. It knows its position very precisely (to the millimeter) and observes 24/7 all satellites (GPS, GLONASS, Galileo, Beidou and local systems like QZSS and IRNSS/NavIC).

A base in the Centipede-RTK network must operate 24 hours a day, 365 days a year.

The result is a data stream (RTCM3) of observations that will be used by another GNSS receiver (the Rover) to correct its position.

INFO

Already have a base station? You can connect it to the Centipede-RTK network. See this page for more details.

Most RTK receivers can be used either as a Rover or as a Base. The following pages will allow you to build and deploy your own GNSS RTK base.
