How do you demonstrate the basics of satellites and / or gps systems?
I have to do a model or hands in a demonstration that could use to demonstrate the basics of satellites and GPS positioning systems. I learned the basics of positioning system and satellite system, but I'm trying to think of an effective way of presenting it. Thanks
Place a skillet large surface area. Mark three points separate the bottom of the pan to indicate the location of their satellites. Ideally, each point satellite will be located in one of the points of an isosceles triangle. Mark a point fourth among the three satellite spots as their destination, the place you want to locate the position fix via the GPS simulated. Fill the pot with water to cover throughout its area, eg, 1 inch of water. Put a device to sit at the bottom of the pot where the destination is marked for the device above the water. Stick a finger in the water during the first "satellite" point of creating a wave. The waves represent signals that GPS satellite. Time to time t1 it takes the wave travel from the first point to the goal. Repeat with the other two satellite points for T2 and T3. To calibrate the speed of a wave V, measure the distance between one of the places Satellite and white, using a meter or yard stick. Then V = S / t, where S is the measured distance and t is the time it took the wave to reach the goal. In a real GPS V = c, the speed of light, so this step is not necessary for a true case of GPS. Given the wave velocity V is the same for all waves can be calculated the distance between the target device and each of the places where they dip the finger to create the waves. Therefore, you must s1 = VT1, VT2 and VT3 = s2 = s3. Repeat these until procedures, for example, N = 30 systems calculated for s1, s2, s3 y. Let S1 = sum (s1) / N, S2 = sum (s2) / sum of N, and S3 = (s3) / N is the average distance to the target from the respective dive sites representing three satellites. This is an important step to minimize measurement errors. Plot each one of three average distances on a piece of paper like spokes around each of the corresponding three-point dive. At the intersection of three radios is the position calculated in the target device. You can order to prove this result, moving the target back and redo the experiment to demonstrate the experimental results correspond to the actual position of the device in the pan. Check your calculated "GPS" results with the actual position is measured with a rod or a tube, will be interesting to see how to calculate your "GPS" measures. Speculation about where the errors could have been. GPS Could I have the same type error? And there you have it … this is how GPS works. On the outside are three or more satellites, you can set a position on the surface of the Earth quite accurately … down to about 1 m of error using the best GPS receivers. And, if you add more satellites, the error will become less because there are more radios that intersect.
