Strict and simplified transformation models, which can be used in case of the position and velocity short-term predictions of GLONASS satellites, have been presented in this study. Comparison of the results of state vector components predictions of the GLONASS satellites, in dependence of the used transformation model, have also been presented. Accuracy of the prediction has been determined on the basis of the analyse of deviations of the predicted positions and velocities of GLONASS satellites from their values given in broadcast ephemeris.

Calculation of position and velocity of GLONASS satellite based on analytical theory of motion / W. Goral in Artificial satellites, vol 50 n° 3 (September 2015)  

Public [article]  inArtificial satellites > vol 50 n° 3 (September 2015) . - pp 105 - 114 Titre : Calculation of position and velocity of GLONASS satellite based on analytical theory of motion Type de document : Article/Communication Auteurs : W. Goral, Auteur ; Bogdan Skorupa, Auteur Année de publication : 2015 Article en page(s) : pp 105 - 114 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Techniques orbitales [Termes descripteurs IGN] constellation GLONASS [Termes descripteurs IGN] position [Termes descripteurs IGN] satellite GLONASS [Termes descripteurs IGN] vitesse Résumé : (auteur) The presented algorithms of computation of orbital elements and positions of GLONASS satellites are based on the asymmetric variant of the generalized problem of two fixed centers. The analytical algorithm embraces the disturbing acceleration due to the second J2 and third J3 coefficients, and partially fourth zonal harmonics in the expansion of the Earth’s gravitational potential. Other main disturbing accelerations – due to the Moon and the Sun attraction – are also computed analytically, where the geocentric position vector of the Moon and the Sun are obtained by evaluating known analytical expressions for their motion. The given numerical examples show that the proposed analytical method for computation of position and velocity of GLONASS satellites can be an interesting alternative for presently used numerical methods.
