he test consisted of equipping a radio-controlled rover with a low-cost u-blox C102-F9R application board connected to a u-blox multi-band/multi-constellation antenna, model ANN-MB-01. The antenna was attached to the roof of the rover.

The data acquisition was conducted in an experimental coffee plantation composed of young coffee trees with a height of about 1.5 m, located at the Federal University of Lavras (UFLA). The rover was guided through the corridors of the coffee plantation, which are approximately 130 m long, collecting and saving, in a personal computer, GPS raw data with interval tracking of 1 second.

The GPS data was collected in .ubx format and converted to RINEX.
