Definition of polar orbit in English: polar orbitnoun A satellite orbit that passes over polar regions, especially one whose plane contains the polar axis. an amateur radio satellite in a polar orbit mass noun the agency maintains four satellites, two in polar orbit Example sentencesExamples - When declared operational in 1964, Transit consisted of five satellites in offset polar orbits circling the Earth at an altitude of about 670 miles.
- He said the experimental satellite will weigh 35 kg and will be placed in a polar orbit, orbiting the earth from pole to pole, at an altitude of 600 to 800 km.
- Depending on your stretch of that definition, a satellite in a perfect polar orbit would pass over each pole once per day and might be called ‘geosynchronous’, but like the time of day at the poles the terminology becomes ambiguous.
- Only about 2% of the time is that satellite ever over something even remotely interesting - it's a very, very low yield - and you only come over that spot with a satellite once a day if it's in a polar orbit.
- By 2001 those satellites (flying in polar orbits and geosynchronous orbits) were equipped not only with cameras but with a range of sensors that employed the latest infrared technology.
