This paper is addressing the application of NAVSTAR GPS in the civilian community with increasing accuracy requirements. NAVSTAR GPS has the potential to meet general worldwide positioning and navigation requirements. Differential NAVSTAR GPS has the potential to meet also increased regional positioning accuracies within few meters and increased regional navigation accuracies by 10 to 15 m. Several land vehicle operators indicated to need this level of accuracy same as marine and aviation operators did. Therefore it seems to be an urgent requirement to standardize differential NAVSTAR GPS services as early as possible for avoiding that user equipment of different manufactures would not work under different differential services. This paper describes the NAVSTAR GPS status, discusses the signal availability for the civilian community, evaluates alternative differential NAVSTAR GPS concepts, indicates the expected performance with differential NAVSTAR GPS, discusses general requirements to the data link and gives some recommandations for standardization. For demonstration of probable performance some preliminary results from user equipment under development is presented.
