What else can I help you with?
There are currently broadcasting GPS satellites?
Yes, there are currently multiple GPS satellites in orbit that provide positioning, navigation, and timing services globally. The Global Positioning System (GPS) is maintained by the United States and typically consists of around 30 operational satellites, ensuring that at least four satellites are visible from any point on Earth at any time. These satellites transmit signals that allow GPS receivers to calculate precise locations. The system is continuously being updated and improved to enhance accuracy and reliability.
Except for light reflection does a satellite eminate any other visible light during night time?
I am not aware of any beacon lights on any satellites. I'm sure the International Space Station has some, for times when the Shuttle is coming in, but what purpose would they serve otherwise? Aircraft have anti-collision lights - to avoid airplanes crashing into each other at night. But satellites generally travel too fast for any visual cues to be useful - and satellites have very limited maneuverability anyway.
Has a longer wavelength than visible light can be used in cooking and communication with satellites?
Microwaves have a longer wavelength than visible light and are commonly used in cooking, as they are able to penetrate food and cause water molecules to vibrate, generating heat. Microwaves are also used in satellite communication to transmit signals due to their ability to travel through the Earth's atmosphere and interact with satellites in orbit.
How many geo stationary satellites are needed to cover the earth at a time?
Please be a little more precise in your meaning when you say "cover" the Earth. For radio or TV communications, three satellites in geosynchronous orbit will be visible from any inhabitable locale on the planet. (The polar regions aren't really "inhabitable", and aren't visible from GEO. ) For navigational purposes, more are required. The GPS system requires line-of-site to FOUR satellites at one time in order to give a good "fix" of your position; the USAF uses 27 satellites to accomplish this, anywhere on the Earth.
Are people visible from outer space?
People are not visible from outer space with the naked eye. The International Space Station and some high-resolution satellites are able to capture images of cities and large structures, but individual people cannot be seen.
Four of Jupiters satellites can be seen from Earth using a telescope What makes these satellites visible?
light emitted by the satellites
Why does the satellite suddenly stop being visible?
A satellite can stop being visible due to factors such as entering the Earth's shadow, changing its orbit, or switching off its reflective surfaces making it harder to see from the ground. Additionally, atmospheric conditions, like clouds or light pollution, can also obstruct visibility of satellites.
When are satellites visible?
When they reflect the light from the sun or moon.
Are there any visible satellites from Concord New Hampshire?
no
Where can one find pictures of earth satellites?
One can find pictures of earth satellites on the NASA Visible Earth online website. NASA Visible Earth is a catalog of NASA images of our home planet, earth. The website "Geology" is where one can also find pictures of earth satellites.
Are planets satellites of the sun?
Yes, the planets can be described as being satellites of the sun.
Are the planets are satellites of the sun?
Yes, the planets can be described as being satellites of the sun.
How do geographers use satellites to study earth?
Satellites carry cameras (visible light, infrared and ultraviolet)and radar. They produce very good images of the earth that can be studied.
What do false colour images from visible light satellites show us?
it shows us nothing

Can you see satellites from the ground?
Yes, it is possible to see satellites from the ground with the naked eye. Satellites are typically visible during the early morning or evening hours when the sun's light reflects off them. They appear as moving points of light in the night sky.
