RTK Satellite Navigation

Basics

• An Abbreviation for Real Time Kinematic Satellite Navigation
• Essentially Satellite Navigation but more precise
• This is done via a basestation sending correction data to the moving componet, known as the "rover unit"
• Many rovers can use one base station See this post on how to do this effectively
• All in all this can produce anywhere from centimeter to single didgit milimeter accuracy depending the setup
• VERY useful for RC and Autonomous Vehicle Applications
• Also used for surveying
• Basestations can be a service for larger scale, or purchased/built and placed/operated by the user

Electronics
