Navigation satellites are also widely used by the military.

Types of satellites and their uses ppt.

Unlike satellites in geo that must always orbit along earth s equator leo satellites do not always have to follow a particular path around earth in the same way their plane can be tilted. Navigation satellites were developed in the 1950s and they rely on the doppler effect to calculate the position of vessels emitting a radio signal. 43 navigational satellites. Navigational satellites are satellites which use radio time signals transmitted to enable mobile receivers on the ground to determine their exact location.

Reconaissance or spy satellites e g. A satellite with a low inclination can use the earth s rotation to help boost it into orbit. Micro satellite below 100 kg 3 nanosatellite below 10 kg. There are also nine pictures of satellites.

Satellites in high earth orbit require the most energy to reach their destination. Types of satellites based on its application are. 1 minisatellite 500100 kg 2. This means there are more available routes for satellites in leo which is one of the reasons why leo is a very commonly used orbit.

Miniaturized satellites are of 3 types. The satellite must be designed specifically to fulfill its role. The type of satellite that is launched to monitor cloud patterns for a weather station will be different than a satellite launched to send television signals across canada. A moon is a natural satellite of earth.

A type of satellite that gives ships and aircraft their coordinate positions on the earth. Satellites can be classified based on their applications orbit in which they are placed. We can categorize satellites in two types namely passive satellites and active satellites. Satellites in a highly inclined orbit such as a polar orbit take more energy than a satellite that circles the earth over the equator.
