Gps - the big idea mathematically
Date: 13-06-2009 | author: Sara Lee
In his mind, it all comes down to speed their travel time math problems when we were in middle school. Remembering the past: If the car running 60 miles per hour for two hours, how to travel how far? Speed (60 mph) x Time (2 hours) = Distance (120 miles). In the case of GPS we test a new radio signals so that the speed of light running or speed of 186.000 miles per second. The problem is measuring the travel time. Planning problems difficult. First, it will be very short. Overhead satellites if they are correct at time of travel will be something like 0.06 seconds. So, we re going to need some really precise clock. We ll talk about those changes.
