The orbit of Cosmos 837 rocket (1976-62E) has been determined at 36 epochs between January and September 1978, using the RAE orbit refinement program PROP6 with about 3000 observations. The inclination was 62.7 degrees and the eccentricity 0.039. The orbital accuracy achieved was between 30 m and 150 m, both radial and crosstrack. The orbit was near 29:2 resonance in 1978 (exact resonance occurred on May 14) and the values of orbital inclination obtained have been analyzed to derived lumped 29th-order geopotential harmonic coefficients. These will be used in future, when enough results at different inclinations have accumulated, to determine individual coefficients of order 29. The values of lumped harmonics obtained from analysis of the values of eccentricity were not well defined, because of the high correlations between them and the errors in removing the very large perturbation (31 km) due to odd zonal harmonics.
