OGO 1 components
Orbiting Geophysical Observatory (OGO) refers to the six satellites launched by the United States that were in use from September 1964 to 1972, designed to study the Earth's magnetosphere.[1] The satellites successfully studied the interactions between the Earth and the Sun, despite a number of technical problems. Each satellite had 20 to 25 instruments. OGO 1, OGO 3, and OGO 5 were in equatorial orbits; OGO 2, OGO 4, and OGO 6 were in lower polar orbits.[2]
