What is the orbit of GPS satellite?
GPS satellites fly in medium Earth orbit (MEO) at an altitude of approximately 20,200 km (12,550 miles). Each satellite circles the Earth twice a day.
How does GPS calculate speed?
The formula for calculating speed is speed equals distance covered divided by the time taken often represented as x = d/t. By using two GPS points (locations) we can calculate the distance covered. *GPS satellites send their positions to receivers on the ground every second.
Is Google Maps GPS speed accurate?
Remember, a gps speed readout is only 100% accurate on a level road when travelling in a straight line. Have a look when next doing 50mph (speedometer) in a 50 zone on the motorway how many trucks with accurately calibrated speedos come past you…

How do you calculate travel time?
Estimate how fast you will go on your trip. Then, divide your total distance by your speed. This will give you an estimation of your travel time. For example, if your trip is 240 miles and you are going to be drive 40 miles an hour, your time will be 240/40 = 6 hours.

How do you calculate distance?
To solve for distance use the formula for distance d = st, or distance equals speed times time. Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t.
What is the formula of speed time and distance?
The formula for speed is speed = distance ÷ time.
