Error Analysis and Quality Control of GPS RTK Technology

GPS RTK plays a great role in measuring and surveying because of its high efficiency,and the key of using GPS RTK is to reduce error and raise precision.The paper analyses the sources of error when GPS RTK is in practical uses,and proposes that it should reduce error to raise precision from environment,instrument,technology management,and enhance quality's control.At last,the authors put forward an example to test GPS RTK technology by reducing error and raising precision.
