What is the glonass?
GLONASS is a constellation of satellites with a similar purpose to the US GPS system with a minimum of 24 satellites. GLONASS is operated by the Russian Federation, and finally became fully operational in 1993 with the full complement of 24 satellites. China has a similar system underway, known as COMPASS, but it has only 10 satellites operational yet, and with the aim of 30 units. A mix of geostationary and low orbit elements. IRNSS (Indian regional navigation satellite system) is also underway, but with 2 geostationary orbiting satellites operational of 7 planned. GALILEO is the navigation system being constructed by the European Union, with 4 (out of 10) of the planned satellites operational. There is also a DORIS system operated by France, but this uses quite a different system. Information from this helps ascertain the elevation of the JASON 1 and JASON 2 systems to a few cm.
How many satellites does India have in space?
India has launched 56 satellites into space to date. Many of which have since completed their missions and are no longer operational, some have been landed.
How many satellites are needed to provide a place on earth?
If the question is regarding finding the latidude and longitude of one point on the earth, the answer is a minimum of three satellites. The method used is called triangulation. If you wish to know the altitude of the point, a minimum of four satellites are needed.
What is the full form of navstar?
NAVigation Satellite Timing And Ranging
What is the different types of natural satellite?
There is different types of artificial satellites, each for different uses. For example : Weather satellites help meteorologists predict the weather or see what's happening at the moment. Typical weather satellites include the TIROS, COSMOS and GOES satellites. The satellites generally contain cameras that can return photos of Earth's weather, either from fixed geostationary positions or from polar orbits. Communications satellites allow telephone and data conversations to be relayed through the satellite. Typical communications satellitesinclude Telstar and Intelsat. The most important feature of a communications satellite is the transponder - a radio thatreceives a conversation at one frequency and then amplifies it and retransmits it back to Earth on anotherfrequency. A satellite normally contains hundreds or thousands of transponders. Communications satellites are usually geosynchronous. Broadcast satellites broadcast television signals from one point to another. • Scientific satellites perform a variety ofscientific missions. The Hubble Space Telescope is themost famous scientific satellite, but there are many others looking at everything from sun spots to gammarays. ( See the article of the telescopes) -> Hiten scientific satellite • Navigational satellites help ships and planes navigate. The most famous are the GPS NAVSTAR satellites, r escue satellites respond to radio distress signals. -> NAVSTAR satellite • Earth observation satellites observe the planet for changes in everything from temperature toforestation to ice-sheet coverage. -> ENVISAT • Military satellites are up there, but much of the actual application information remains secret. Intelligence-gathering possibilities using high-tech electronic and sophisticated photographic-equipment reconnaissance are endless. Applications may include relaying encrypted communication, nuclear monitoring, observing enemy movements, early warning of missile launches, eavesdropping on terrestrial radio links, radar imaging, photography (using what are essentially large telescopes (see the article on the telescopes ) that take pictures of militarily interesting areas)

Is a GPS system based on a constellation of four satellites strategically placed around the Earth?
No, for GPS to work there must be 24 operational satellites in orbit, with 12 of those above the horizon as seen from any point on earth.For a GPS receiver to get a latitude-longitude fix it must receive signals from a minimum of 3 satellites and to also get altitude it must receive signals from a minimum of 4 satellites. Each satellite that it receives above these minimums allows the receiver to get a more precise fix.
When was the gps navstar first launched?
The first satellite in the system, Navstar 1, was launched February 22, 1978.
