This actually depends on the orbital radius, or distance from Earth's surface (or center). The further away the satellite is, the slower it travels to stay in orbit (related to Kepler's second law). A satellite that is really close to the atmosphere and barely in space needs to travel at about 7800m/s. A satellite can speed up and increase its tangential velocity to make its orbit bigger. A bigger orbit results in a lower speed. Interestingly, this means that an orbiter speeds up to slow down. Likewise, a satellite in a high orbit can fire its engines backwards to reduce its speed to get into a smaller, faster orbit, ultimately speeding up.
================================
In an orbit that's not a perfect circle, the speed in orbit is always changing.
The satellite moves faster when it's closer to the Earth, and slower when it's
farther out.
Every form of electromagnetic radiation, including radio, travels at the same speed
when they're in the same medium. It's the speed we call the "speed of light".
In vacuum, that speed is:
299,792,458 meters per second
186,282 miles per second.
varies depending on size & shape of orbit. 16,000 mph is a typical value for a circular low earth orbit.
The right answer is 3.87 km/sec. You can calculate this by multiplying two pi times the orbital radius of 26560 km then dividing by the orbital period which is 12 hrs.

How many GPS Satellites does the US Deptartment of Defense have?
There are currently 30 healthy GPS satellites in orbit.
Where are GPS satellite signals processed?
GPS signals are processed in the GPS unit and displayed, and they are also processed via three Global Position Satellites. All four units work together and process GPS signals (some to the satellites from the GPS, and some from the satellites to the GPS) to create an accurate position.
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.
A system made of 25 satellites?
GPS
How long will gps satellites last?
If you taking care of the GPS, It will last about 5 years
What do gps satellites find?
GPS satellites do not 'find' anything, that is not their purpose.
Distance from earth to gps satellite?
The distance from Earth to a GPS satellite is approximately 20,200 kilometers on average. This distance varies as the satellites orbit the Earth. GPS signals travel at the speed of light, so the time it takes for a signal to travel from a satellite to a GPS receiver on Earth is used to calculate the distance. GPS relies on multiple satellites to provide accurate location information.
What type of orbit is used by gps satellites subsynchronous or sunsynchronous?
Geostationary satellites are the ones used for GPS satellites.
How is data inputted in gps?
GPS devices receive data from satellites through signals transmitted by the satellites. The GPS receiver in the device then processes these signals to determine the device's location based on the time it takes for the signals to travel from the satellites to the receiver. This location data is then used to provide navigation information to the user.
What are two names of satellites?
GPS IIA-1 NAVSTAR 1 (Both GPS satellites)

How does a GPS (Global Positioning System) work?
A GPS works by satellites that are located in outer space. These satellites are connected with cameras that show the whole earth. You GPS and the satellites systems are working together to provide maps for you.
Why does a satellite travel over different parts of the earth?
Because most satellites are not 'geostationary'. A geostationary satellite orbits the Earth at the same speed that the Earth spins on its axis - such as the GPS grid, or TV relay satellites. Most satellites travel faster or slower than the Earth spins.
Do you need a susbscrption to use a gps?
No. GPS Satellites are free to receive.
Can you have a GPS system in Colorado?
You can use a GPS anywhere the satellites shine.
Do you need to be connected to the internet to use the GPS?
No as GPS is obtained from satellites.
