Polar orbits are used for Earth-mapping, reconnaissance satellites, as well as for some weather satellites. [2] The Iridium satellite constellation uses a polar orbit to provide telecommunications services. Near-polar orbiting satellites commonly choose a sun-synchronous orbit, where each successive orbital pass occurs at the same local time of ...
Spymesat, [16] by Orbit Logic, [17] a mobile app for iOS and Android, computes pass predictions for any selected location for available commercial and unclassified government high-resolution imaging satellites and provides real-time notifications and dynamic real-time imaging resolution and satellite position information and maps during ...
The Joint Polar Satellite System (JPSS) is the latest generation of U.S. polar-orbiting, non-geosynchronous, environmental satellites. JPSS will provide the global environmental data used in numerical weather prediction models for forecasts, and scientific data used for climate monitoring.
The Polar-orbiting Operational Environmental Satellite (POES) is a constellation of polar orbiting weather satellites funded by the National Oceanic and Atmospheric Administration (NOAA) and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) with the intent of improving the accuracy and detail of weather analysis and forecasting.

Repeat orbit: An orbit where the ground track of the satellite repeats after a period of time. Gangale orbit: a solar orbit near Mars whose period is one Martian year, but whose eccentricity and inclination both differ from that of Mars such that a relay satellite in a Gangale orbit is visible from Earth even during solar conjunction.

KSAT operates two polar ground stations optimized for low Earth orbit (LEO) satellites, the other being TrollSat at Troll in Antarctica. [22] These are the only two ground stations able to see a polar-orbiting satellite on every revolution. [24] By using both stations, customers can communicate with a satellite twice per orbit. [10]
The Global Geospace Science (GGS) Polar satellite was a NASA science spacecraft designed to study the polar magnetosphere and aurorae. It was launched into orbit in February 1996, and continued operations until the program was terminated in April 2008. The spacecraft remains in orbit, though it is now inactive. Polar is the sister ship to GGS Wind.
