Which Satellite Is Used Exclusively For Education?
EDUSAT is the first Indian satellite built exclusively for serving the educational sector. It is mainly intended to meet the demand for an interactive satellite based distance education system for the country and strongly reflects India’s commitment to use space technology for national development, especially for the development of the population in remote and rural locations.
The 1950 kg EDUSAT was launched from Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota, into a Geosynchronous Transfer Orbit (GTO) by ISRO’s Geosynchronous Satellite Launch Vehicle (GSLV). From GTO, EDUSAT will reach the 36,000 km high Geostationary Orbit (GSO) by firing, in stages, its on board Liquid Apogee Motor (LAM).
In GSO, the satellite will be co-located with KALPANA-1 and INSAT-3C satellites at 74 deg East longitude. Compared to the satellites launched in the INSAT series so far, EDUSAT will have several new technologies. The spacecraft is built around a standardized spacecraft bus called I-2K.
It has a multiple spot beam antenna with 1.2 m reflector to direct precisely the Ku band spot beams towards their intended regions of India, a dual core bent heat pipe for thermal control, high efficiency multi-junction solar cells and an improved thruster configuration for optimised propellant use for orbit and orientation maintenance.
The satellite uses radiatively cooled Ku-band Travelling Wave Tube Amplifiers (TWTAs) and dielectrically loaded C-band DEMULTIPLEXER for its communication payloads. EDUSAT carries five Ku-band transponders providing spot beams, one Ku-band transponder providing a national beam and six Extended C-band transponders with national coverage beam.

What is the difference between LEO and MEO?
LEO and MEO satellites – Low Earth Orbit and Medium Earth Orbit respectively – both come under the mantle of non-geostationary-orbit (NGSO) satellites. LEO satellites orbit at an altitude below 2,000km/1,243 miles above mean sea level, while MEO satellites orbit in the region between LEO and GEO (geostationary) satellites – 2,000-35,800km/1,243-22,245 miles.
- LEO satellites are commonly deployed for communications purposes and the transmission of scientific data, while MEO satellites cover a variety of uses including communications, navigation and the exchange of geodetic/space environment data.
- As LEO and MEO satellites do not synchronise with the Earth’s rotation and orbit the earth more rapidly than GEO satellites – an orbital period of 128 minutes or less for LEO, and an average of between 2 and 8 hours for MEO – multiple satellites are required in order to achieve seamless coverage.
However, one of the main advantages of NGSO satellites over GEO satellites is considerably lower latency. Whereas GEO satellites have roughly 550 milliseconds of round-trip latency time, LEO satellites boast a latency of 240 milliseconds, signifying a distinct advantage in the sphere of real-time applications. One of the earliest MEO satellites to be launched was Telstar in 1962, the first communications satellite. Today, concentrated investment in technological development and infrastructure is driving the design and manufacture of myriad new LEO and MEO satellite constellations, with considerable potential for military and defence deployment as well as a profusion of uses in the commercial and leisure maritime sectors.

What is MEO and GEO?
3. MEO (Medium Earth Orbit) –
A MEO satellite situates in orbit somewhere between 6,000 km to 20,000 km above the earth’s surface. MEO satellites are similar to LEO satellites in the context of functionality. MEO satellites are similar to LEO satellite in functionality. Medium earth orbit satellites are visible for much longer periods of time than LEO satellites usually between 2 to 8 hours. MEO satellites have a larger coverage area than Low Earth Orbit satellites. MEOs can be positioned somewhere between LEOs and GEOs, both in terms of their orbit and due to their advantages and disadvantages.
Why does GPS use MEO?
Use of MEO – Two medium Earth orbits are particularly significant. A satellite in the at an altitude of approximately 20,200 kilometres (12,600 mi) has an orbital period of 12 hours and passes over the same two spots on the equator every day. This reliably predictable orbit is used by the (GPS),
Other navigation satellite systems use similar medium Earth orbits including (with an altitude of 19,100 kilometres, 11,900 mi), (with an altitude of 23,222 kilometres, 14,429 mi) and (with an altitude of 21,528 kilometres, 13,377 mi). The has a high of 63.4° and high of 0.722 with a period of 12 hours, so a satellite spends most of its orbit above the chosen area in high latitudes.
This orbit was used by the (now defunct) North American and satellites and the Russian military communications satellites, after which it is named.
- Communications satellites in MEO include the and forthcoming constellations for and to maritime, aero and remote locations (with an altitude of 8,063 kilometres, 5,010 mi).
- Communications satellites to cover the North and South Pole are also put in MEO.
- 1, an experimental communications satellite launched in 1962, orbited in MEO.
- In May 2022, mobile network operator,, and satellite owner and operator, used SES’s MEO to demonstrate that MEO satellites could be used to provide high-speed mobile internet to remote regions of Kazakhstan for reliable video calling, conferencing and streaming, and web browsing, with a five times lower than on the existing platform based on satellites.
Why do we need 4 satellites?
Satellite Navigation – GPS – How It Works 
Satellite Navigation is based on a global network of satellites that transmit radio signals from medium earth orbit. Users of Satellite Navigation are most familiar with the 31 Global Positioning System (GPS) satellites developed and operated by the United States.
Three other constellations also provide similar services. Collectively, these constellations and their augmentations are called Global Navigation Satellite Systems (GNSS). The other constellations are GLONASS developed and operated by the Russian Federation, Galileo developed and operated by the European Union, and BeiDou, developed and operated by China.
All providers have offered free use of their respective systems to the international community. All providers have developed International Civil Aviation Organization (ICAO) Standards and Recommended Practices to support use of these constellations for aviation.
The basic GPS service provides users with approximately 7.0 meter accuracy, 95% of the time, anywhere on or near the surface of the earth. To accomplish this, each of the 31 satellites emits signals that enable receivers through a combination of signals from at least four satellites, to determine their location and time.
GPS satellites carry atomic clocks that provide extremely accurate time. The time information is placed in the codes broadcast by the satellite so that a receiver can continuously determine the time the signal was broadcast. The signal contains data that a receiver uses to compute the locations of the satellites and to make other adjustments needed for accurate positioning.
The receiver uses the time difference between the time of signal reception and the broadcast time to compute the distance, or range, from the receiver to the satellite. The receiver must account for propagation delays or decreases in the signal’s speed caused by the ionosphere and the troposphere. With information about the ranges to three satellites and the location of the satellite when the signal was sent, the receiver can compute its own three-dimensional position.
An atomic clock synchronized to GPS is required in order to compute ranges from these three signals. However, by taking a measurement from a fourth satellite, the receiver avoids the need for an atomic clock. Thus, the receiver uses four satellites to compute latitude, longitude, altitude, and time.

Why is 4 satellites needed?
GPS satellites and positioning: one satellite – It takes four GPS satellites to calculate a precise location on the Earth using the Global Positioning System: three to determine a position on the Earth, and one to adjust for the error in the receiver’s clock. If you were 15,000 miles from only one satellite (satellite with red sphere), you could be anywhere on an imaginary red sphere that has a radius equal to the number of miles from the satellite (15,000 miles).
