Abstract

The positioning precision of the high-performance GPS（global positioning system） receiver-Trimble 5800 and its feasibility measuring in the complex forest terrain was tested. The results show that when Trimble 5800 GPS receiver dose single point positioning in difference terrain，the 65% inner precision of WGS-84 coordinates is 0 － 2 m and 30% of it is 2 － 5 m，its maximum deviation is less than 8 m. The outer precision of the average observations is less than 5 m，and evenly distributes in 0 － 5 m after coordinate transformation. As a result，if it takes the deviation between known coordinate and observations on a known point as the correct parameter of other points observations measured in the same timerange，this will effectively improve the positioning precision. In the distance and area measurement，the relative error of single point positioning with Trimble 5800 is less than 1/300 and 1% when the datum measured by Total Staions were taken as reference value. so Trimble 5800 receiver precision is better than the precision of handy GPS.［Ch，1 fig. 8 tab. 8 ref.］
