Abstract:

The DODGE Department of Defense Gravity Experiment satellite was launched on July 1, 1967 to an altitude of 18,000 statute miles into a near-synchronous orbit. The satellite was designed, as an experiment to demonstrate two- and three-axis gravity-gradient stabilization using magnetic and hysteresis damping techniques. A solar cellbattery power system furnishes all of the electrical energy required to operate the satellite subsystems. The solar power generating capability is 45 watts average. A 6-ampere-hour 10-volt nickel-cadmium battery operates peak electrical loads during light and dark orbits as required. DC-to-AC inverters and DC-to-DC converters transform the solarbattery voltage to the proper levels required to operate the on-board electrical loads. The power system contains protective devices for safeguarding the battery against excessive discharge currents and charging voltages.
