a.r Force Spa.e Comma.d is interested in improving the a.cura.y of GPS receiver positioning, na.iga.ion, a.d timing. To this end, it is useful to identify a.set of optima. sa.ellite constella.ions where ea.h corresponds to a.configura.ion specifying the number of sa.ellites in ea.h orbita. pla.e. These constella.ions could then be ma.nta.ned in a.libra.y for future use a. sa.ellites fa.l a.d a.e la.nched. We utilize symmetry in the geometry of the GPS sa.ellite orbits to pa.tition the configura.ions into a.much sma.ler set of equiva.ence cla.ses where ea.h cla.s ha. the sa.e overa.l receiver a.cura.y performa.ce. We a.ply a.cla.sica. a.gebra.c combina.oria. result, Polya.s Theorem, to count a.d ca.egorize the cla.ses. Incorpora.ing our results into a.GPS constella.ion optimiza.ion computer tool will reduce run time by a.out a. order of ma.nitude. We a.ply other a.gebra.c a.d combina.oria. techniques in origina. wa.s to count the cla.s sizes a.d the cla.ses tha. conta.n a.given number of sa.ellites. Fina.ly, we brea. the equiva.ence cla.ses into a.still sma.ler set of new ＂structure＂ cla.ses tha. a.e useful in a.plying the GPS computer tool.
