ORS 4 (Octahedral
Research Satellite 4), also known as Environmental Research
Satellite-18 (ERS-18), was launched
on 28 April 1967. The elliptical orbit had an apogee of 111,553 km, a
perigee of 8631 km, and an inclination of 32.9 degrees. The orbital period
was 2840 minutes. The spacecraft was a spin stabilized octahe... | <urn:uuid:dd3b131b-676d-4277-b3b2-175cf92c8b94> | 3.1875 | 635 | Knowledge Article | Science & Tech. | 55.552974 |
