(1) Divided according to the working principle, it can be divided into code -related receivers, square receivers and hybrid receivers. Code -related receiver can produce a copy code that is exactly the same as the satellite rangefinder structure that is tested. The C/A or P code is used, the condition is to master the measurement of the sistor measurement. The square receiver uses the square technology of the carrier signal to remove the adjustment code to obtain the necessary carrier signal for the carrier phase measurement. The machine only uses the satellite signal without decoding, and there is no need to master the measured code structure. The hybrid receiver uses the advantages of code -related technologies and square technologies. At the same time, obtains the observation of code phase and precision carrier phase observation, and is widely used.
(2) According to the type of signal channel type of the receiver, it can be divided into multi -channel receiver, sequential channel receiver, and multi -road reuse channel receiver. Multi -channel receiver has multiple satellite signal channels, and each channel only continuously tracks one satellite signal, also known as continuous tracking receiver. There are only 1-2 signal channels for the sequential channel receiver. In order to track multiple satellites, under the corresponding software control, the satellite signals are tracking in order in order. /s), the tracking of satellite signals is discontinuous. The multi-way reuse channel receiver is similar to the sequential channel receiver, and only 1-2 signal channels. Under the control of the corresponding software control, the satellite signals are tracked in order. Short (less than 20 m/s) can maintain continuous tracking of satellite signals.
(3) Divide the frequency of satellite signals received by the receiving, can be divided into single -frequency receiving machines and dual -frequency receiver. Single -frequency receiving machine (L1) only receives the modulated L1 signal. Although the parameters provided by the navigation electrical text can be used to impact the ionization layer on the observation capacity, but because the correction model is not perfect and the accuracy is poor, it is mainly used for less than 20 km. Short -base line precision positioning. Dual -frequency receiving machine (L1+L2) receives two signals: L1 and L2 at the same time. Using dual -frequency technology, the impact of the refraction of the ionization of the ionization on the observation can be eliminated or weakened. The positioning accuracy is high. Dividing the satellite signal according to the signal frequency is more types of use
