How many minimum number of geostationary satellite needed for uninterrupted global coverage?
In theory, 2 satellites in diametrically opposite geosynchronous orbits could cover the planet. In order for the satellites to communicate, a minimum of 3 would be needed, each at a 60 degree angle to the others. At this point, the strength and quality of coverage increases proportionally to the number of satellites.
How many GPS satellites are there and when were they put in orbit?
GPS SatellitesThere are 30 GPS satellites -- called NAVSTARs -- in place and the oldest one was launched in 1989. These are just the ones in operation now -- another 22 have been launched since the program started in 1978, but are no longer working. The design of the satellites has remained essentially the same over the years; the differences have just been in their operations.The first 11 satellites, known as Group I and designed by Rockwell International, were launched into orbit between 1978 and 1985 from Vandenburg Air Force Base in California. Each of these satellites contained one Cesium and two Rubidium atomic clocks and could provide navigation and standard positioning information. Continuous contact with the Ground Control Segment (CS) was required for their operation. They were designed to last five years, but most lasted much longer.The next group of 9 satellites are called Group II and were also designed by Rockwell. These were the first to provide precision positioning information for military use and to be able to operate for 14 days without contact with the CS. Group II satellites contained four clocks two Cesium and two Rubidium and were launched between February 1989 and October 1990 from Cape Canaveral Air Force Station in Florida. They were designed to last 7.3 years and two currently remain in operation.The Group IIA satellites were next group to be designed by Rockwell and numbered 19. They are similar to the Group II satellites, except they have the ability to operate 180 days without contact with CS. These were launched from Cape Canaveral between November 1990 and November 1997. All but three of these satellites are still in operation.The most recent type, Group IIR, were designed by Lockheed Martin and each have three Rubidium clocks. They were designed to provide more accurate information through a combination of ranging techniques and communication between the satellites. They are also designed to last slightly longer (7.8 years) and to have improved independent controls. There are currently 12 such satellites in orbit the most recent launched in November 2004.The satellites are launched via a Delta II rocket designed by Boeing. These are expendable launch vehicles (ELVs), meaning they are intended for one use only. Each of these ELVs consists of the following:Stage I which contains fuel and oxygen tanks to supply the main engine during its climb;Solid rocket booster motors to provide additional thrust during the first two minutes of flight;Stage II which contains the fuel and oxidizer tanks that supply the engine needed to insert the ELV into orbit and the brains of the ELV, including its guidance system;Stage III that has a solid rocket motor to provide any needed velocity change.More input from others:According to SMC Fact Sheet (URLhttp://www.losangeles.af.mil/smc/pa/fact_sheets/gps_fs.htm), as well as Garmin (URL http://www.garmin.com/aboutGPS/), there are 24 satellites in the system with an additional 4 on reserve.
How does a GPS satellite work with a GPS device?
signals from at least 3 satellites send signals to and receive signals from the gps which are then triangulated to give the exact position of the GPS unit. Most GPS units are receive only. That is they must receive positional and timing information from the GPS satellite constellation. The internal processor them computes your position based upon this data(triangulation). Generally receiving data from three or more satellite's is needed to be produce a good fix (your position) but this is also dependent upon the geometry of the satellites. The best fixes are obtained when you have signals from three or more satellites which are geometrically separated by 45 degrees.
Why was sputnik 2 launched?
The history of sputnik dates back to December 1954. It was developed as part of a larger picture for rocket technology. It was also put into development as the rest of the countries were also working on similar projects.

Who can launch a satellite?
Government space agencies, private aerospace companies, and international organizations can launch satellites into space. These entities have the technology, expertise, and resources needed for satellite launches. Additionally, some universities and research institutions may also have the capability to launch small satellites.
At least how many satellites are needed to calculate the position?
It takes at least 3 satellites.
How many satellites needed to get a position?
Typically, three satellites are needed to determine a 2D position (latitude and longitude), while four satellites are needed to determine a 3D position (latitude, longitude, and altitude) using GPS technology.
How many satellites do you need to have a full GPS signal?
A minimum of 4 satellites is needed to obtain a full GPS signal. These satellites are used to triangulate your position accurately on Earth.
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 kind of education is needed for computer software?
Information technologies.

How do you launch a dll file?
You do not launch a DLL. It's used by something else and will start up when needed. Read up on DLL file.
What is a launch pad made out of?
A launch pad is typically made out of concrete and steel to withstand the heat, pressure, and vibrations produced during a rocket launch. It also includes various systems for fueling, power supply, and communication needed for the launch process.
