Why does radio and satellite reception deteriorate when the sun goes down?

All satellite equipment, whether it be for communications, TV or radio, operates on its own specific radio frequency to communicate with the satellite. Light also gives off a radio frequency. "White light" which is what the sun gives out, is a full spectrum frequency. This means that every radio frequency there is, the sun is emmiting. So for you, when the sun goes down, the satellite which your radio equipment gets its signal from is probably in the path of the sun. Since the sun's rays are so powerful it inteferes with the satellites signal to your radio equipment.
Let me know if I am right on this, you have XM radio. I am a satellite communications systems operator/maintainer in the US Army. Just curious because the XM satellites are geostationary which means that they are constantly in the same place in the sky in relation to the ground. You probably wouldn't have this problem with Sirius radio because their satellites have a highly elliptical orbit which means that there are multiple satellites moving over the Western Hemisphere where there are always two moving across the skies over North America. Since there are two always in the sky in different locations, if one was in the suns path, your radio would receive its signal from the other.
Just as a little satellite humor, we sometimes have problems with our equipment when we try to locate the satellite in the sky. If the satellite is near the sun, our dish sometimes locks onto the sun. A couple of times I've seen when the sun crosses the path of our signal, the dish will start following the sun and we lose communications.

Does the satellite requires power to revolve around the earth?
No. Once the satellite is placed in orbit, its momentum will keep it orbiting along its original path - more of less. "More or less" means: 1. The satellite may need minute adjustments to its position, so that it can photograph its intended targets (stars/planets, the earth), or can keep in contact with its intended radio/television/mobile phone services, and 2. A satellite's orbit will slowly decay, and the satellite would eventually come into the outer atmosphere, begin to slow down, and burn up as its orbit brought it into denser air. For both these reasons, satellites may use small "positioning" thrusters to steer and to regain orbital speed.
What type of radio sounds do radio telescopes hear?
Stars broadcast from x-rays down through infrared, and radio telescopes take advantage of this by tuning in to the emissions, dubbed "radio" to differentiate from "optical" here, not because the star is necessarily being monitored in our "radio" spectrum.
What channel is Grey's Anatomy on?
For cable (which I have) it is channel 7abcThat depends on where you live, have cable or satellite reception. Where I live its channel 7in Ireland (north and south) its on rte1and in the UK its on living (sky)
How is a weather satellite in polar orbit able to view Earths surface?
From the question, I'm guessing that when the questioner reads the term "polar orbit", he's picturing the satellite doing a little tiny circle in the sky over the North Pole. This is not an accurate understanding of the term. Remember that the center of the orbit of an artificial satellite has to be at the center of the earth. A 'polar orbit' is an orbit that covers both poles. If you picture the globe of the earth, the satellite's orbit is a circle standing up, with the satellite traveling up and down, passing over both poles in each complete revolution of the earth. As the earth rotates, every point on earth passes under the orbit, and sooner or later, every point on earth will be visible from the satellite.
Where is Radio Shack Canada based?
The original Radio Shack is based in the United States of America. However they do have locations in Canada which have been closed down. The Canadian stores now go under the name 'The Source.'
Why i don't get good radio reception in my car?
if your window is down you cant get good radio network so if you have your window open you can pick up radio signal!
Does the Satellite Receiver go down and you lose reception when it rains outside?
You may loose your signal if there is very bad weather in your area.
What is propogation delay in satellite?
A propagation delay is the amount of time it takes radio waves to travel from the surface of the Earth to the satellite and then back down to the Earth. The calculation of the delay is based upon the altitude and position of the satellite systems.
Can a skeleton deteriorate?
yes ur bones can break and be shaved down so yes your skeleton can deteriorate
How to activate satellite radio with out paying?
Not on this website. This is a class operation over here, and that's a sleazy, slimy question that essentially boils down to theft when you get right down to it.
Is the word freeze a synonym for the word deteriorate?
No. Synonyms for deteriorate would be degrade, rot, break down, worsen...
How do you get satellite images of the earth?
The satellite takes pictures of the earth, and sends the photos down by radio, as a digital data-stream. Maybe kind of like the same way you send pictures to your friend's cellphone, you suppose ?
The reasons behind the down fall of IT Industry throughout the world?
Radio Physics(science) covers a wide range of modern disciplines which are based on propagation & reception of radio waves and their usage. Accordingly,Radio Physics can be said as a base of Radio Astronomy,Radio Remote Sensing,Radio communication,Electromegnetic,Radio Metrology,etc., are some of our science & technology disciplines. Also,in the present era of IT industry, explosion in information technology and satellite,terrestrial and mobile communication,the radio waves have become an integral part of our day to day life.However,due to its comfortable facilities of present Industry,the thinking of persons come down and they are still based on techniques of Radio Physics. There are still open problems in science & technology where we have no solution. Moreover,IT industry does not want to take such task. In other words,It industry is much busy in earning money instead of thinking other direction by making use of IT.(see,www.opmisra.com).
When was Down in the Shacks Where the Satellite Dishes Grow created?
Down in the Shacks Where the Satellite Dishes Grow was created in 1992.
What are telecommunication links?
In satellite communication, up link refers to the signal traveling up to the satellite while down link refers to the signal coming from the satellite down to earth.
What is media class in advertising?
A media class is a vehicle for carrying the advertisers message to the target audience. Broad media classes include television, newspaper, radio etc. As you are getting more specific these broad classes would be narrowed down so that you consider, for example, broadcast radio or satellite radio.
What happens to the satellite if its life period is over?
i think it might shut down. if its a space satellite it will shut down and float away.
