Development of a DGPS Digital Beacon Receiver

()

Abstract:

A design technique of a Differential Global Positioning System (DGPS) digital beacon receiver is presented which can be used to improve the positioning precision. After a brief review of the basic principle of DGPS and GPS-DGPS system functions, the theory of an active non-directional DGPS receiving antenna and the hardware/software design process for digital DGPS receiving unit are emphasized.
