ABSTRACT: After the liberation of Selective Availability (S/A) several GPS receivers started to have enough accuracy or precision for work with grid sampling in Precision Agriculture. There are few articles describing the accuracy and precision of these receivers. The objective of this work was compared and calculated the accuracy of two models very used for grid sampling in Brazil. The study was done in a flat surface, common in the Cerrados region. The geographical reference was determined by DGPS collecting data for 10 hous. The tested models (Garmin GPSIII Plus and Garmin etrex Vista) were evaluated for 5 days in the period of 7 a.m. to 17 p.m. The concept of Circular Error Probability (CEP) was uded for the accuracy and precision calculation.
