Recently the use of a network of multiple GPS reference stations for generating carrier phase-based corrections has emerged with great promise for use in real-time environments. However, little research has been conducted on the distribution of these correction to potential GPS users located within, and surrounding, the network coverage area. This is an integrated part of real-time kinematic DGPS, and it must be adequately adressed before a pratical realization of the multi-reference station concept is implemented. The focus of this paper is to present a comprehensive summary of some of the multiple reference station methods, with specific attention directed toward the correction generation and dissemination processes. More specifically, the various multi-reference station methodologies have been categorized according to their underlying correction generation framework, but will be discusse in terms of the correction dissemination options presented by various authors. The four main categories of methods investigated in this paper are : (a) partial derivative algorithms, (b) linear interpolation algorithms, (c) condition adjustement algorithms and (d) virtual reference station methodologies.
