  Reasons for GPS drift

  Once we understand the positioning principle of GPS, we will find that although mathematical principles are simple, it is complex to achieve two known conditions through physical means.

  Firstly, when a satellite flies in the sky, no one can guarantee that it will be in its own orbit without any deviation, and there will always be some degree of deviation.

  Secondly, it is also impossible to install a cesium atomic clock on your GPS receiver. The propagation speed of radio waves is about 300000 kilometers per second. After simple calculation, you will find that if there is a time error of 0.00001 seconds, how much is the distance difference? Even if there is no time error, the propagation of radio waves in the air will be influenced by many factors, such as weather.

  The above impact is not the most significant, but the more important reason is how much satellite signal you can receive. The GPS signal is very weak, and with such a small ceramic antenna on the receiver, do you still expect any good results? So basically, if there is something blocking you, you will not receive the signal. Even if you receive ten or eight satellites with strong signals, will they be very accurate? No, if you happen to happen to have these ten satellites gathered in a pile for a meeting, or lined up in a neat line to come home from school, then you will be in dire straits. Whether positioning is accurate or not, the distribution position of satellites is also a very important influencing factor. A good state is that strong signal satellites are distributed in equilateral triangles in three corners of the sky, with relative distances as large as possible, and should not be arranged in an approximate straight line. This is determined by the mathematical principles of GPS.

  The above mentioned are only uncontrollable technical errors, belonging to the category of "natural disasters". Since ancient times, "natural disasters" have always been inseparable from "human disasters". When the level of technological development is enough to reduce these errors to a very low level, you will also find another very embarrassing problem: people do not want you to achieve such high accuracy at all. As you all know, civilian GPS and military receiving frequency points are different. Civilian GPS has scrambling codes and is specifically designed for you to cause trouble!
