1. Use three -frequency signal
GPS uses a dual -frequency signal, and Beidou uses a three -frequency signal. Based on the differences that the dual -frequency carrier signal is affected by the delay of the ionization of the electrical layer, the effect of the ionization layer on the electromagnetic wave signal can be weakened by calculating the ionization layer delay.
The use of three -frequency signals can better offset the high -level error of the ionizer, the positioning is more accurate, and when a certain frequency point cannot be used, the dual -frequency can be switched. This is the post -issuing advantage of Beidou.
2. Combination of active positioning and passive positioning
The active positioning refers to sending the location information to the satellite during the positioning process, and the passive positioning receiver does not need to send information to the satellite. Under the active positioning technology, as long as there are 2 satellites, you can locate, and at least 4 satellites must be available under normal passive positioning to achieve positioning. In some cases of poor searches in some environment, the superiority of active technology is reflected.
3. Short newspaper communication service
This is a unique technology in China. The so -called shorthe newspaper refers to the two -way information transmission between the user terminal and the satellite through satellite signals, which is more suitable for communication in emergencies. During the 2008 Wenchuan earthquake, the only way to communicate in the earthquake area was the Beidou generation.
4. Domestic monitoring
The Beidou III system first uses the measured star link technology of the KA frequency band. This technology enables all Beidou satellites into a large net. Each star can "call", can be ranged, one -star, star -oriented, which greatly improves the accuracy of satellite positioning. In addition, the star -carrier clocks of each satellite can be synchronized to improve the accuracy of the time synchronization of the entire navigation system.
