Abstract
The invention relates to a ground navigation method based on a big dipper, which is mainly characterized in that a ground navigation receiver consists of two parts, namely an antenna unit and a receiving unit, wherein the antenna unit can capture and track a big dipper satellite, and receive and amplify a big dipper signal when the satellite rises from a horizon line; and the receiving unit records, demodulates and filters the big dipper signal, reduces a navigation message transmitted by the big dipper satellite, solves the propagation time and a carrier phase difference of the signal in a horoscope chamber, obtains navigation positioning data in real time or obtains data of positioning, speed logging, timing and the like in an after-logging processing manner.
Description
Technical field
The present invention relates to ground navigation, be specifically related to a kind of ground navigation based on the Big Dipper.
Background technology
In view of the significance of satellite navigation in economic life and national defence, China tentatively built up Beidou I navigation positioning system in 2003, and came into operation.In 5.12 Wenchuan special violent earthquakes, No. one, the Big Dipper plays a significant role in earthquake relief work.China's second generation autonomous satellite navigational system " No. two, the Big Dipper " is also under construction.Land station's database is the sub-project that China's Big Dipper No. two satellite navigation and location systems are built; land station's database needs for the storage of satellite business data provides 7*24 hour not shut down service; the software systems of a high reliability; and agile methods weakens the constraint of project planning, system and document discipline; be applied in the high-new estrangement mega project of high-tech and must improve; and and some sense of discipline viewpoints in conventional procedure model combine, could ensure large-scale development progress with reliable software and quality.
Summary of the invention
The invention provides a kind of ground navigation method based on the Big Dipper.
In order to reach above-mentioned purpose, the technical scheme of employing is as follows:
Ground navigation method based on the Big Dipper is mainly a ground navigation receiver, and it is made up of antenna element and receiving element two parts.
Antenna element: when big-dipper satellite rises from local horizon, to catch, tracking satellite, receives and amplifies Big Dipper signal.
Receiving element: record Big Dipper signal also carries out solution mediation filtering process to signal, restore the navigation message that big-dipper satellite sends, solution asks the travel-time of signal between divining by astrology and carrier phase difference, real-time acquisition navigation positioning data or adopt the mode of after logging process, obtain locate, test the speed, the data such as timing.
Specific embodiments
Based on a ground navigation method for the Big Dipper, method is: ground navigation receiver, and it is made up of antenna element and receiving element two parts.Antenna element is when big-dipper satellite rises from local horizon, can catch, tracking satellite, receives and amplifies Big Dipper signal.Receiving element is record Big Dipper signal and carries out solution mediation filtering process to signal, restore the navigation message that big-dipper satellite sends, solution asks the travel-time of signal between divining by astrology and carrier phase difference, real-time acquisition navigation positioning data or adopt the mode of after logging process, obtain locate, test the speed, the data such as timing.
