ABSTRACT
ABSTRACT
Both the static GPS system and the RTK GPS system are the
single-frequency, high-precision differential positioning systems
that process signal-frequency signals, mainly carrier phase
received by at least two receivers at the same time.
Firstly, the dissertation introduces the applications of using
GPS receivers in the surveying, make sure the purpose and
significance of the task.
Secondly, the dissertation discusses both the time system and
the coordination system of GPS, the signals received by the GPS
receiver, it is more important that the dissertation discusses
detailedly the principle of the single-frequency, high-precision
differential positioning utilizing the carrier phase in both of
systems.
Thirdly, the designs of the static GPS receiver and the RTK
receiver, the module of the GPS network adjustment are
introduced.
At last, the errors that infect the differential positioning are
listed and analyzed simply.
The dissertation could be considered as the technical report
of the GPS receivers designed by Chongqing University and
South Surveying and Mapping Instrument Company. Today, a
serial of receivers have reached the advanced technical level of
the same kind products in the world and taken place of the same
kind import receivers because about 600 receivers have been
produced and sold during recent years.
