OGO
American earth magnetosphere satellite. Research satellite built by TRW for NASA, USA. Launched 1964 - 1969. Used 3-axis stabilized box-shaped satellite bus.

AKA: Orbiting Geophysical Laborator;Orbiting Geophysical Laboratory. Status: Operational 1964. First Launch: 1964-09-05. Last Launch: 1969-06-05. Number: 6 . Gross mass: 588 kg (1,296 lb).

The purpose of the six Orbiting Geophysical Observatories was to conduct diversified geophysical experiments to obtain a better understanding of the earth as a planet and to develop and operate a standardized observatory-type satellite.

OGO consisted of a main body, two solar panels, each with a solar-oriented experiment package (SOEP), two orbital plane experiment packages (OPEP) and six appendages, EP-1 through EP-6, supporting the boom experiment packages. The main body of the spacecraft was attitude controlled by means of horizon scanners and gas jets so that its orientation was maintained constant with respect to the earth and the sun. The solar panels rotated on a horizontal axis extending transversely through the main body of the spacecraft. The rotation of the panels was activated by sun sensors so that the panels received maximum sunlight. Seven experiments were mounted on the solar panels (the SOEP package). An additional axis, oriented vertically across the front of the main body, carried seven experiments (the OPEP package). Nominally, these sensors observed in a forward direction in the orbital plane of the satellite. The sensors could be rotated more than 90 deg relative to the nominal observing position and more than 90 deg between the upper and lower OPEP groups mounted on either end of this axis.
