Description
Technical field
The utility model discloses a kind of electronic measurement and control teaching experimental, particularly a kind of GPS GPS principle of simulation experiment instrument.
Background technology
GPS (Global Positioning System, usually be called for short GPS) be a kind of round-the-clock of U.S. Department of Defense's development, the navigational system of space reference, can satisfy be positioned at the whole world Anywhere or the military user of terrestrial space accurately determine three positions and three motions and the needs of time continuously.It is a round orbiter navigational system of middle distance.
The GPS Global Positioning System (GPS) is made up of three parts: space segment-GPS constellation; Ground Control part-ground monitoring system; Customer equipment part-GPS signal receiver.
1. space segment
The space segment of GPS is made up of 24 work satellites, and it is positioned at the sky of 20 200km apart from the face of land, is evenly distributed on (4 of each orbital planes) on 6 orbital planes, and orbit inclination is 55 °.In addition, also have 4 active redundancy satellites in orbit.The distribution of satellite makes in the whole world Anywhere, all can observe the satellite more than 4 any time, and can keep the geometric figure of good location calculation accuracy.This just provides continuous in time worldwide navigation ability.The GPS satellite produces two groups of codes, and one group is called C/ A sign indicating number (Coarse/ Acquisition Code11023MHz); One group is called P sign indicating number (Precise Code 10123MHz), and the P sign indicating number is higher because of frequency, is not subject to disturb, and therefore the bearing accuracy height is subjected to US military control, and is provided with password, and general among the people can't the deciphering is mainly the US military service.After C/ A sign indicating number people painstakingly reduces precision for taking measures, the main open use among the people of giving.
2. Ground Control part
The Ground Control part is by a master station, and 5 global monitoring stations and 3 ground control stations are formed.The monitoring station all be fitted with accurate caesium clock and can continuous coverage to the receiver of all visible satellites.The monitoring station comprises ionosphere and weather data with the moonscope data that obtain, and through after the rough handling, is sent to master station.Master station is collected tracking data from each monitoring station, calculates the track and the timing parameter of satellite, then the result is delivered to 3 ground control stations.When Ground Control stands in every satellite transit to the sky, these navigation datas and master station instruction are injected into satellite.This injection and was carried out last injection to every GPS satellite once a day before satellite leaves the injection plant reach.If certain land station breaks down, also available a period of time of the navigation information that in satellite, prestores so, but navigation accuracy can reduce gradually.
3. customer equipment part
Customer equipment part is the GPS signal receiver.Its major function is can capture by the selected satellite to be measured of certain satellite cutoff angle, and follows the tracks of the operation of these satellites.Arrive the satellite-signal of tracking when receiver acquisition after, can measure receiving antenna, demodulate data such as satellite orbit parameter to the pseudo-distance of satellite and the rate of change of distance.According to these data, the little process computer in the receiver just can position calculating by the positioning calculation method, calculate the longitude and latitude of user geographic location, highly, information such as speed, time.The poster processing soft bag of software and GPS data constitutes complete GPS subscriber equipment in receiver hardware and the machine.The structure of GPS receiver is divided into antenna element and receiving element two parts.Receiver generally adopts in the machine and the outer two kinds of direct supplys of machine.When being to change external power, the purpose that internal power supply is set do not interrupt Continuous Observation.With the machine external power in opportunity battery charge automatically.After the shutdown, self-contained battery is for the power supply of RAM storer, to prevent loss of data.Present various types of receiver volume is more and more littler, and weight is more and more lighter, is convenient to field inspection and uses.
The realization of a series of functions of GPS all is that realize the route of transmission with the electromagnetic wave, and can't represent this process to the student objectively in the teaching.No matter existing GPS experiment instrument is to adopt actual GPS receiver module to be connected with computer, still adopts the demonstrator of solid model, all lacks intuitively to show in the demonstration of GPS principle of work, is unfavorable for student's fully understanding for this process.
