Method for transmitting satellite data
First Claim
1. A method for transmitting satellite data for a global navigation satellite system, in which position data of satellites of the global navigation satellite system are transmitted to a navigation device, wherein the position data of a subset of satellites associated with a specific satellite are transmitted to the navigation device by the specific satellite and wherein the subset of satellites contains a selection of those satellites, whose distance with respect to the specific satellite, averaged over a repetition period of the inter-satellite distance, is shortest.

Abstract
In a method for transmitting satellite data of a global navigation satellite system each satellite transmit position data of neighboring satellites to a navigation device on the earth. The subset of neighboring satellites with respect to a specific satellite is determined by averaging over a period of the inter-satellite distance. The subsets are further restricted to the condition that all visible satellites are referenced by the position data of at least one other satellite. This requirement can be met by choosing appropriate permutations among the satellites with shortest distance.
