What else can I help you with?
Why does g.p.s. need 4 satellites?
GPS needs signals from at least 4 satellites to accurately calculate a 3D position on Earth. By receiving signals from multiple satellites, the GPS device can triangulate its position using the known positions of the satellites. This allows for highly accurate location determination.
Why can't we see satellites orbiting?
You can see satellites orbiting. If you go on a clear night to somewhere which is far from city lights, you will sometimes see dots moving across the sky - these are satellites reflecting sunlight.
What are three things that reflect light in space?
Planets: Bodies in space that reflect light from a nearby star, such as the Earth reflecting sunlight. Moons: Natural satellites that reflect light from their parent planet or from the sun, like Earth's moon reflecting sunlight. Asteroids: Rocky or metallic objects in space that can reflect sunlight if they are large enough and have a shiny surface.
What can be seen from the earth because they reflect light from an object?
Objects that reflect light and can be seen from Earth include the Moon and planets in our solar system, such as Venus and Mars. These celestial bodies do not produce their own light but instead reflect sunlight, making them visible in the night sky. Additionally, artificial satellites and space debris can also reflect light, sometimes appearing as bright points moving across the sky.
How many satellite does Dstv have?
DStv primarily broadcasts its services using a fleet of satellites, with the most notable being the Intelsat series. Specifically, DStv utilizes several satellites, including Intelsat 20, Intelsat 7, and others, to cover different regions in Africa. The exact number of satellites may vary based on operational needs and expansions, but generally, they operate with multiple satellites to ensure comprehensive coverage.
When are satellites visible?
When they reflect the light from the sun or moon.
Does satellites in space transfer light?
If by transfer you mean reflect then yes they do.
Do satellites produce light?
planets don't produce their own light. They just reflect light
Can sun light reflect from a satellite?
Yes, sunlight can reflect off of a satellite's surface, similar to how sunlight can reflect off of other objects. This reflection can make satellites visible as they pass overhead, especially in the early morning or late evening when the sun is low in the sky.
What color are satellites?
White. Irrespective of the money spent on paint and coatings, the light they reflect is pretty much white.

What metal is found on satellites that reflects heat from the sun?
Gold foil is normally used to reflect solar heat in satellites because it has the highest reflectivity in the infrared spectrum (and, as NASA used to say, solid Gold was too expensive!)
Why are satellites useful in everyday life?
They are used to reflect radio waves to improve long distance communications and they are used for GPS location systems
How are planets different from satellites?
simple! planets are huge or normally bigger than satellites in terms of mass, area and size. planets normally have a atmosphere like the earth. planets revolve around the sun whereas satellites revolve around the planet. both of them are non luminous object which means they reflect the light from the sun. satellites are usually fragments of a planet when it was forming.
Does marketing merely reflect the needs and wants of consumers?
yeah
Why can't we see satellites orbiting?
You can see satellites orbiting. If you go on a clear night to somewhere which is far from city lights, you will sometimes see dots moving across the sky - these are satellites reflecting sunlight.
What were satellites originally made for?
The first artificial satellite that had a particular purpose (other than just for scientific research) was the Echo satellite; a large mylar balloon placed in orbit to reflect radio signals back to the Earth. Now, satellites are used for all kinds of communications; TV, cell phones, overseas phone calls, internet and such; weather satellites that help to predict the weather and track storms, and reconnaissance satellites that take photos of the Earth. Oh; GPS satellites.
