Over the past couple of weeks and months I have been evaluating and building a somewhat affordable high precision GNSS solution to achieve centimeter-level accuracy in order to track the collection of plants in my garden. I am not going much deeper into the functional aspects of the project. For that please refer to my recent presentation slides from SpringOne 2020. But I will provide a list of parts that I used to build the project.

TBD :-)

When you need high precision Global Navigation Satellite System (GNSS) support, one of the best economical choices is the Ardusimple simpleRTK2B. I am using the Long Range Starter Kit that consists of a base station and a rover. By using 2 simpleRTK2B boards that communicate with each other, I am able to take advantage of Real-Time Kinematic (RTK) positioning which gives me centimeter accuracy. The simpleRTK2B has a convenient connector for Xbee radio modules which in my case is used for the…
