Orbits This will be a multi part series about Orbits and the GPS system. Part 1: Satellite Orbits (This Post) Part 2: GPS Satellites and Distances [WIP] Part 3: Correcting for non-precise time [WIP] Before getting into the GPS part of this series we first need to know some simple things about GPS. There are many different GPS Satellites but they operate on the same principal. They have multiple atomic clocks which are used to get a precise time. Then send that time in a RF signal to earth so that devices can retrieve that time and use it to calculate how long it took to get there. Using the time distance and knowing that the RF signal will be traveling at the Speed of light you can get the distance from the satellite to the receiver(You). Using at least 3 (when you also have a atomic clock) or 4 you can figure out where in space you are located. Then you can convert this to latitude, longitude and height on the earth. ...

This is how I make Toto embed MathJax in to the page using Tex markup. <script type="math/tex; mode=display"> \begin{align} x &= 100011_2 \\ &= 100_2 * 2^3 + 011_2 \end{align} </script> It looks like this when rendered The mode=display makes it so that it is centered in case that is what you need because it looks better than left or right aligned. The rest of the markup is taken from Tex. ...
