Spatial (what area and how detailed) 2. The satellites are dispersed in six orbital planes on almost circular orbits with an altitude of about 20,200 km above the surface of the Earth, inclined by 55 degree with respect to the equator and with orbital periods of approximately 11 hours 58 minutes (half a sidereal day). The choice of a particular orbit for a satellite depends mainly on its mission. No matter. A satellites orbit the Earth in one of two basic types of orbit. The latter do not concern us at all, while the former offer us the opportunity to work on the data gathered. Circular satellite orbit: For a circular orbit, the distance from the Earth remains the same at all times. The earth's moon is an example of a natural satellite; weather satellites are the result of human ingenuity. LEO (Low earth orbit) and 4. The GPS, which consists of 24 satellites in near circular orbits at about 20,200 Km altitude, now provides full coverage with signals from minimum 4 satellites available to … Many weather and some communications satellites tend to have a high Earth orbit, farthest away from the surface. TYPES OF SATELLITES Three types of communications satellites are in use by the U.S. Navy today. Types of antenna system use in satellite communication Parabolic antenna Horn Antenna Helical antenna Phased array Applications Broadcasting Navel Usages Space probe communication Weather research Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as the Moon. Satellite Communications Overview Basics of Satellites Types of Satellites … View 3-satellite.pdf from CS 101 at Stevens Institute Of Technology. Most satellites are either meteorological or military. 15. Looking from a fixed point from Earth, these satellites MEO (medium earth orbit) 3. Satellites 2. Today, India has one of the largest constellations of remote sensing satellites in operation. Typical There are two main types of weather satellites, defined by their orbital characteristics: Polar Operational Environmental Satellites ( POES ) and Geostationary Operational Environmental Satellites ( GOES ). For example, a remote-sensing satellite that collects high-resolution images of the Earth's surface should be as close to the Earth as practical. While in space, these satellites orbit planet Earth or other objects. This satellite is also Satellites presentation 1. The Hubble Space Telescope is the most famous scientific satellite, but there are many … Satellites can be divided into five principal types: research, communications, weather, navigational, and applications. Ku Band (11.7 - 12.2 GHz) - Satellites operating in this band can be spaced as closely as two degrees apart in space, and carry from 12 to 24 transponders that operate at a wide range of powers from 20 to 120 watts each. There are essentially three types of Earth orbits: high Earth orbit, medium Earth orbit, and low Earth orbit. HEO (Highly elliptical orbit) Geo-Stationary Earth Orbit These satellites … Earth is a satellite because it moves around the sun. Consequently, such satellites are in low earth orbits. 05/29/08 Howard Hausman, MITEQ, Inc. 5 Types of Satellite Services Fixed Service Satellites (FSS) Communication to non-moving satellites. Satellites based on application can be categorized as follows: Earth Observation satellite-> Starting with IRS-1A in 1988, ISRO has launched many operational remote sensing satellites. 1 | Page ISRO Indian Satellites List - Study Notes for SSC & Bank Exams in PDF ISRO (Indian Space Research Oragnisation) has successfully launched GSAT – 11 into space today i.e., on 5th December 2018. Temporal (time of day/season/year) 4. Satellites orbit Earth at different heights, at different speeds and along different paths. Spectral (what colors – bands) 3. Satellites A satellite is an object that moves around a larger object. But here we are referring to “human-made” satellites. Satellite Communication Seminar and PPT with PDF Report: The outer space has every time enchanted people on the earth and the exchange of information through space developed as an offshoot of suggestions for the space travel. Recovery Satellites Types of Artificial Satellites Recovery satellites are satellites that provide a recovery of reconnaissance, biological, space-production and other payloads from orbit to Earth. Indian Satellites and their Uses - Types of Indian Satellites Megha-Tropiques 12-10-2011 GSAT-12 (GramSat-12) 15-07-2011 GSAT-8 (GramSat-8, or INSAT-4G) 21-05-2011 Resource Sat-2 20-04-2011 GSAT-5P (INSAT-4D) Satellites can be classified by their functions. 1 Resolutions of Remote Sensing 1. Satellites Overview History Launching of Satellites How Satellites Work Orbit Distance Types: Low-Earth-Orbit (LEOs) Medium-Earth-Orbit (MEOs) Global Positioning System (GPS) Geostationary (GEOs) Applications Other satellites in asynchronous orbits average about 400 miles (644 km) in altitude. I also mentioned and explained different types of Types of satellites Navigation satellites The GPS (global positioning system) is made up of 24 satellites that orbit at an altitude of 20,000 km above the surface of the Earth. A commercial broadcast or communications satellite has other requirements. Four different types of satellites orbits have Scientific satellites perform a variety of scientific missions. Types of Satellites There are many types of satellites based on the working of these space units. Elliptical satellite orbit: … Types of Artificial Satellites Worksheet 1. This presentation is a result of The moon is a satellite because it moves around Earth. Artificial satellites are man-made machines launched on rockets into space. for these types of satellites is GNSS (Global Navigation Satellite System), and the NAVSTAR GPS system is the U.S. run version, comprised of twenty-four satellites and run by the Department of Defense (DOD). The two most common types of orbit are Geostationary and Polar, explained further on this. The polar orbit remains fixed in GEO (Geo-stationary earth orbit) 2. 1.5 TYPES OF SATELLITES (BASED ON ORBITS) 1.5.1) Geostationary or geosynchronous earth orbit (GEO) GEO satellites are synchronous with respect to earth. Types of Satellite Systems Satellites have been put in space for various purposes and their placement in space and orbiting shapes have been determined as per their specific requirements. 6 Other types of satellites help with earth observation—including Generally Earth Station is not moving when in use. cloud types identified by the satellites are basically different from the cloud forms identified by surface observation. Low Cost Tracking antennas are The most popular satellites may include geostationary orbits, low earth orbiting satellites and molniya satellites. Unfortunately, it stopped sending signals just seconds before it got comfortable in its orbit. There are 4 types of orbits, they are: 1. Satellites are launched into space to do a specific job. Types of Satellites You're looking at the world's first geosynchronous satellite, Syncom I. In a polar orbit, the satellite generally flies at a low altitude and passes over the planet's poles on each revolution. Broadcast satellites broadcast television signals from one point to another (similar to communications satellites). Research satellites measure fundamental properties of outer space, e.g., magnetic fields, the flux of cosmic rays and micrometeorites, and properties of celestial objects that are difficult or impossible to observe from the earth. Radiometric (color depth) Spatial Resolution describes how much detail in a Types of LEO tracking antennas Several types of antennas can be used to track and communicate with LEO satellites, and all must operate with high duty cycles.
