High code rate can improve accuracy
The Code rate of L1 is very low, and the time it takes for each encoding is about 10 by 6 seconds. Of course, these signals are transmitted at the speed of light, that is, three times by three times, then the time is about 300 meters at the speed of light. The encoding rate of L5 is ten times that of L1, and each coding takes ten times smaller than L1, becoming the seventh negative power 10. Multiplying at a speed of about 30 meters. Of course, this is the resolution of satellites. If multiple satellites are used at the same time and the lighting range of many satellites is used as a intersection point, the accuracy of L1 will be far less than 300 meters. And L5 is more accurate.
There are many high -rise buildings in the city, and satellite signals become very messy after being reflected by these buildings. Interweater with the correct direct signal, we call it multiple paths (many paths). Even if the small signal delay caused by small reflexes, these signals are transmitted at the speed of light, and the distance obtained by the speed of light is very large. These are the root causes of the wrong.
The L5 signal has a high coding rate, and the spectrum density is easier to concentrate. Although the L5 also reflects, the possibility of the new peak value of the new peak of the new peak of the spectral density after the reflection of the error signal and the correct direct signal form the spectral density, which makes it easier for the calculation engine to find the direct satellite signal.
The high -encoding speed of L5 is so easy to use. Why not use L5 directly? This is because L1's low -bit rate is easier to capture, and we must not sacrifice the positioning time. Therefore, L1 is also called approximate obtaining code. After the capture signal, L5 can participate in the calculation together.
