- It can be seen that the role of the GPS navigation satellite system is to continuously transmit navigation messages. However, because the user receives the clock and satellite machine using a carrier clock may not always synchronized, so in addition to the 3D coordinates of X, y, Z users, but also the introduction of a t that is the time difference between the satellite and the receiver as unknown, and then use the 4 equation the 4 unknowns out. So if you want to know the location of the receiver, at least to receive the signal of 4 satellites.The GPS receiver may receive for accurate timing information to nanosecond time; for forecasting ephemeris in the next few months which the approximate location of the satellite; used to calculate the required positioning satellite coordinates of the broadcast ephemeris, the accuracy of several meters to tens of meters (each satellite is different at any time change) and GPS system information; such as satellite status.The GPS receiver can get the distance from the satellite to the receiver by the measurement of the code, because it contains the receiver satellite clock error and atmospheric propagation error, it is called the pseudo distance. The pseudo distance measured by the 0A code is called the pseudo distance of the UA code, the precision is about 20 meters, the pseudo distance measured by the P code is called the pseudo distance of the P code, and the precision is about 2 meters.
- Q: GPS if you can not use the military code to crack the military GPS high-precision positioning?
- 1, since it is "secret" crack, even if the people's Liberation Army will tell you?2, this involves GPS channel coding problem (I just took a course last Saturday), and crack the password is completely different concepts of the two. You confuse this crack with the password. It is a very complicated process to encrypt the spread spectrum codes of military channels. I learned one semester is not fully understood... Is spreading code added scrambling encryption and interference technology etc.. And the channel cycle is at least a few days, to try to crack do not want to think.
