S.M. Klosko,C. A. Wagner +1 more
TLDR
In this paper, it is shown that the unique spectrum of information for each satellite contained within a comprehensive spherical harmonic model can be represented by simple gravitational constraint equations (lumped harmonics), all such constraints are harmonic in the argument of perigee (ω) with constants determinable directly from tracking data or reconstituted from the comprehensive solution.About:

Substorm onsets observed by CRRES: Determination of energetic particle source regions
TL;DR: In this article, a method of using single-satellite measurements of near-dispersionless substorm onsets, together with the observed "drift echoes" of these injections, to establish a "source region" for the energetic particles observed at onset is presented.

Substorm injection of relativistic electrons to geosynchronous orbit during the great magnetic storm of March 24, 1991
J. C. Ingraham,Thomas E. Cayton,Richard D. Belian,R. A. Christensen,R. H. W. Friedel,M. M. Meier,Geoffrey D. Reeves,M. G. Tuszewski +7 more
TL;DR: In this article, the authors investigated the very large delayed buildup of relativistic electron flux in the outer zone during a 1.5-day period beginning 2 days after onset of the main phase of the March 1991 magnetic storm.
The role of orbit errors in processing of satellite altimeter data
TL;DR: In this article, the problem of minimizing the crossover differences of profiles measured by the satellite radar has been investigated using either SEASAT observations or simulated data and it was found that the individual solutions resemble a concentration of signal near the signal per revolution frequency in the radial orbit error spectrum.

Earth's gravity field to the sixteenth degree and station coordinates from satellite and terrestrial data.
E. M. Gaposchkin,K. Lambeck +1 more
TL;DR: In this paper, the Earth gravity field and satellite tracking stations positions geodetic parameters in geocentric reference frame and positions geodesic parameters in the reference frame of the Earth's gravity field.
Improvement in the geopotential derived from satellite and surface data (GEM 7 and 8)
TL;DR: In this article, a refinement was obtained in the earth's gravitational field using satellite and surface data using a more complete treatment of data previously employed on 27 satellites, the new satellite solution (Goddard Earth Model 7) includes 64,000 laser measurements taken on 7 satellites during the international satellite geodesy experiment (ISAGEX) program.
