In this study, accuracy and availability of SPS-GPS (Standard Positioning Service GPS) receiver as a positioning device was evaluated by a fixed-point and site test in a tea field. The SPS-GPS has a positioning precision of about 5.33 m (2 d RMS) with continuous observation for 12 hours at fixed-point. By using GPS, plotting and computing 1349m(2)(+-3%)area of tea field can be done easily in 13 minutes by a single operator. Therefore, GPS has sufficient accuracy, and is a simple device to collect geographical information.
