The original COSPAS/SARSAT system used polar orbiting satellites but in recent years the system has been expanded to also include 4 geostationary satellites.

It was also to have been the forerunner of another generation of rockets to launch polar satellites in the 1990's, but the failure today was seen as throwing these and other objectives into doubt.

At 1:49 PST, Discoverer 1 was launched from Vandenberg Air Force Base to serve as a "north-south polar satellite".

Jake's put up a set of six of polar orbiting satellites to keep track of me, she reminded herself; there'd be one close enough to pick up my signal all the time.

Then last year, Dr. Frank announced what appeared to be a stunning confirmation: images from a polar satellite that appeared to show the comets' tracks.

The NOAA-NASA team also will build, launch and operate two more polar satellites under the Joint Polar Satellite System.

India has polar orbiting satellites as well.

A tactical computer will monitor speed, and a polar satellite will provide infrared images of wind patterns and Gulf Stream currents.

Additionally, BMEWS keeps track of polar orbiting satellites.
