The Gravity Gradient Test Satellite was launched by the US Air Force from Cape Canaveral LC41 aboard a Titan IIIC rocket on June 16, 1966, at 14:00:01 UTC. [3] The satellite was launched along with seven IDCSP satellites, with which it shared a bus. [4] In contrast to the solar-powered IDCSP satellites, GGTS was battery powered. [4]
Accuracy is not a great concern here as high drag satellite cases do not remain in "deep space" for very long as the orbit quickly becomes lower and near circular. SDP4 also adds Lunar–Solar gravity perturbations to all orbits, and Earth resonance terms specifically for 24-hour geostationary and 12-hour Molniya orbits .
Parts-per-million chart of the relative mass distribution of the Solar System, each cubelet denoting 2 × 10 24 kg. This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius.
Gravity and climate. The mission will track changes in global sea levels, glaciers, and ice sheets, as well as large lake and river water levels, and soil moisture.

Gravity gradiometry is the study of variations in the Earth's gravity field via measurements of the spatial gradient of gravitational acceleration. The gravity gradient tensor is a 3x3 tensor representing the partial derivatives, along each coordinate axis , of each of the three components of the acceleration vector ( g = [ g x g y g z ] T ...
The Department of Defense Gravity Experiment (DODGE) satellite was the first successful use of the method in a near-geosynchronous orbit on the satellite in July 1967. [3] Gravity-gradient stabilization was first used in low Earth orbit and was tested unsuccessfully for geosynchronous orbit in the Applications Technology Satellites ATS-2, ATS-4 ...
