What is the Round Trip time of a RF signal for GEO satellites?
Mahossen
the speed of light = 299792458 m / s
GEO (Geostationary Earth Orbit) = 35863000 m above the Earth's surface
round trip time = 2*(35863000)/299792458 =0.239 s
the time needed for an RF signal to reach a GEO satellite and gets retransmitted back to a ground station on earth is approximately 240 milliseconds
(assuming zero signal propagation/processing time in the satellite and equatorial ground station location with the same longitude as the satellite slot)

How do satellites aid in map making?
they are using the maps at that time
What is a function of a GPS satellite?
GPS satellites provide location and time information in all weather, anywhere on or near the Earth, where there is an unobstructed line of sight to four or more GPS satellites.
Explain how a communications satellite is used?
http://library.thinkquest.org/03oct/02144/basics/satcomm.htm Satellite Communication Satellites have now become an integral part of the worldwide communication systems. Although long-range and long distance communication took place much before the introduction of satellite systems, they had a lot of disadvantages. Point - to - point communication systems are very difficult in the case of remote & isolated locations, which are surrounded by oceans, mountains and other obstacles created by nature. The satellite is nothing more than a radio-relay station But, they have one potential advantage- The capability of a direct line of sight path to 98% (excluding the polar caps, which are in accessible to satellites) of the earth's surface. One of the most important event in the history of satellite communication took place when COMSAT or communication satellite corporation, launched four satellites within 6 years that is between 1965 to 1979. The first of these series was the 'Early Bird' , which was launched in 1965. This was the first communication station to handle worldwide commercial telephone traffic from a fixed position in space. The next series INTELSAT was a group of satellites that served 150 stations in 80 countries. ..................................... get the points and write the essay urself
What should be considered when camping?
all the right equipment and have signal and have a good time
How many satellites are there in space?
That depends on what you call a satellite. The correct use of the word simply means an object caught in earths orbit. If this is what you are looking for there are litterally tens of thousands of objects from small meteorites to lost tools and rocket stages floating in orbit. So much so that it is now becomming increasingly dangerous to put new vehicles in space as the debris orbits at around 17000 miles per hour. If man made satellites for communications is what you are searching for then thats difficult to gauge. It's unlikely that most countries will admit to placing spy satellites in space to the true figure is difficult to say, but The Goddard Space Flight Center's lists 2,271 satellites currently in orbit. Russia has the most satellites currently in orbit, with 1,324 satellites, followed by the U.S. with 658.
What is a Greyhound round-trip?
A Greyhound round-trip means you are paying for the return trip in advance. Some round-trip tickets are open-ended (with no designated return date) or have a set date (and time) for returning to the departure location.
How do you calculate Round trip time?
Add the time it takes to get there to the time it takes to come back.
What does gps use to locate information about where you are located?
Triangulation to known orbital positions of satellites by measuring signal time delays.
What kind of help do satellites give car drivers and airplane pilots?
Navigation. The Global Positioning System (GPS) provides location and time information for anywhere on the Earth via a series of satellites in geostationary orbits. The time it takes for the driver/pilot to send a signal to the satellites and receive it back again can be used to work out how far away you are from the satellites, which is used to work out where you are.
What is round trip flight?
One that takes you to where you want to go and brings you back again.
How is a communication satellite is used?
A communications satellite operates as a transceiver (TRANSmitter - reCEIVER). Signals from a base station on Earth are sent to a satellite receiver. The data is either stored for a period of time or sent immediately to a transmitter on the same satellite. The transmitters on satellites are positioned to transmit towards Earth or towards other satellites. A base station on Earth will receive the transmitted signals and pass them to land based equipment. As satellite signals rely on line of sight, they each have a range over which they can send signals. Too far round the Earth and the signal won't make it. That's why they can also transmit to other satellites before the signal is finally returned to Earth, far round the globe. The data carried by communication satellites is used for a wide variety of applications. Television, telephones, computer networks and far more are regularly sent to and from satellites.
What is the limiting factor in the time required to transfer a file using TFTP?
TFTP can transfer a maximum of 512 bytes per client server round trip with its stop and wait protocol. Maximum throughput of TFTP = 512 bytes/ round trip time(client-server) We assume for the Ethernet, the Round trip time = 3 ms The maximum throughput is around 170,000 bytes/sec
What is an excursion ticket?
a round-trip ticket at a reduced price. Often for use within a limited period of time.
How much does a train ticket cost from Brmingham to Northahamton?
Birmingham New Street - Northampton (standard class): £13.40 (off-peak one-way) £14.10 (any time one-way) £13.50 (off-peak round trip, return same day) £17.00 (off-peak round trip, return within 1 month) £19.10 (any time round trip, return within 1 month) off-peak = after 09.00 on weekdays, any time at weekends
What is the basic concept behind GPS electronics?
A Global Positioning System device receives signals sent by GPS satellites high above the Earth and calculates its position on Earth by timing the signals received. The satellites send out information which contains the time the signal was transmitted and the position the satellite was relative to Earth at the time of transmission.
How do I book a flexible round trip flight ticket?
A flexible round trip flight can be had by booking a unrestricted Y coach fare. It allows you to take as long a time you want. You can change the schedule as many times as you want, before incurring any fees or charges.
What is the decent price for a coach plane ticket going from la to New York?
To answer this question we need to know time period, time of day, and if it is round trip. I suggest you contact an airline or use a travel website. I live in California and a fair round trip price to NY I would think would be 150.00-250.00.
