Abstract

An approach is submitted to a research based on orbital dice for GLONASS SV ephemeris determination on condition that intersatellite range measurements are used.  The formulation and proof is made for sufficient conditions of uniqueness of the orbital dice improvement using intersatellite range measurements.  In addition, mathematical proof is made for satisfiability of sufficient conditions in case of GLONASS system.  Analytical estimations are derived for orbital dice relative coordinate improvement errors subject to intersatellite range measurements errors.  Derived results allow to relate characteristics of moving orbital dice with observability of broadcast ephemeris improvement problem and as well as with processing algorithm effectiveness for intersatellite range measurements.
