(Summary description): Factors Affecting the Design of GPS Surveying Technology The GPS module field involves a wide range of fields, so the technical design of the field stage is a complex technical management issue. After a comprehensive analysis, the following factors should be considered: (1) Factors related to measuring stations: network density; network layout plan; time allocation, repeated station setting and design of overlapping points; (2) Factors related to observation satellites Number of observation satellites; satellite signal quality; pattern strength factor; satellite elevation angle; ephemeris source. (3) Factors related to the instrument, at least two receivers are used for precise relative positioning; antenna, if the design quality and stability of the antenna are not good, it will bring a series of errors; recording equipment, which can be cassette data Tape or floppy disk. (4) Logistical factors include the number of receivers and their sources and periods of use; scheduling of units at various time periods in the survey area; other field equipment, mainly performance tools and communication equipment.
