Essentials of Physical Geography
There are two distinctively different types of orbits: the polar orbit and the
geostationary orbit (sometimes called a geosynchronous orbit), each with a
different purpose. The polar orbit was developed first; as its name implies, the
satellite orbits ...
Robert Gabler, James Petersen, L. Trapasso, 2006
Near polar orbit Polar orbits circle Earth approximately from pole to pole and use
the movement of Earth as it turns on its axis to image small areas (perhaps 100 X
100 km) to gain good detail of the surface. This orbital technique yields nearly ...

Apollo: The Lost and Forgotten Missions
If a polar orbit mission was scheduled this way (using a Saturn V) once orbital
insertions had been achieved the plane of the orbit would have to be shifted (
using the S-IVB) to attain the desired 40°-45°. This method was hugely expensive
in ...

Polar Orbit (PO): An orbit that goes over both the North and the South Pole is
called a Polar Orbit, although the more correct term would be near polar orbits.
These orbits have an inclination near 90ı, which allows the satellite to see
virtually ...

S/C mass = 50 kg, power = 30 W peak.954' Orbit: Sun-synchronous polar orbit,
altitude = 534 km, inclination =97. 7". The S/C re-entered the Earth's atmosphere
on October 13, 1989 after eight years in orbit. Sensors/Payload: CCD camera, ...

Basic Principles of Physics
When the satellite rotates in an orbit that takes it over the north and south poles, it
is called a polar orbit. Anyother orbital path is called an inclined orbit. A satellite
which revolves in polar orbit around earth is known as polar satellite. The angle ...
A satellite revolves around the earth can take three different paths (orbits). i)
Equatorial orbit. ii) Polar orbit iii) Inclined orbit. When the satellite rotates in an
orbit which is above the equator is called as equatorial orbit. When the satellite
rotates ...

The Principles of Astronomical Telescope Design
5.1.1.4 Polar Orbit A polar orbit is an orbit which passes above, or nearly above,
both poles of the earth. It, therefore, has an inclination angle of, or very close to,
90 degrees to the earth's equator. Since a satellite on this orbit will have a fixed ...

To Reach the High Frontier: A History of U.S. Launch Vehicles
A northerly launch into polar orbit of 8-20 degrees azimuth would necessitate a
path over a land mass; and most safety, abort, and political constraints would
have to be waived. This prohibits polar orbit launches from KSC. It should be
noted, ...

CK-12 Earth Science for Middle School
Another useful orbit is the polar orbit (Figure below). The satellite orbits at a
distance of several hundred kilometers. It makes one complete orbit around the
Earth from the North Pole to the South Pole about every 90 minutes. In this same
...
