Description
Technical field
Present invention relates generally to satellite navigation teaching experimental equipment fields, refer in particular to a kind of Beidou/GNSS satellite navigation religion
It learns and experiment cloud platform.
Background technique
GNSS is the English contracting of Global Navigation Satellite System (Global Navigation Satellite System)
It writes, is generally made of space segment, ground segment and user segment three parts.GNSS mentions for the anywhere of the earth and terrestrial space
For round-the-clock, continuous accurate Position, Velocity and Time information.Currently, Global Satellite Navigation System mainly includes the north of China
Bucket three (abbreviation BDS), the GPS system in the U.S., Russian GLONASS system and European Galileo system.These are
The service range of system all covers the whole world, to constitute global four large satellite navigation system.
Beidou No. two region satellite navigation systems in China's are since 2012 end of the year turn up service, and wide range of services is in country
Economic construction and Defense Force's construction.Beidou two is in rescue and relief work, communications and transportation, mapping, logistics, sea fishery, intelligence
Intelligent city, precision agriculture etc. have played important function.Up to now, the Beidou three fundamental system construction that 19 stars are completed.
It is expected that the year two thousand twenty or so, Beidou three will build up satellite navigation system covering the whole world.As north is built up in the year two thousand twenty front and back in China's
It struggles against Global Satellite Navigation System (i.e. " Beidou three "), domestic satallite navigation market will enter the Beidou epoch.
Under mobile Internet, smart city and " made in China " time equivalence background, satellite navigation and positioning has become people
A part indispensable in daily life.People improve study, research navigation phase to the understanding of satellite navigation importance
The strong will for closing knowledge is even more to exist infinitely to satellite navigation system particularly with the knowledge such as vast university student group
Explore desire and curiosity.Meanwhile satellite navigation industry, especially Beidou satellite navigation system scientific research, production, using etc. produce
The a large amount of professional technician of the development need of industry.Satellite navigation instruments used for education can make student convenient, intuitive with aided education
Understanding satellite navigation system working principle, understanding and understanding to satellite navigation system are enhanced by hands-on.
Such as: patent (Authorization Notice No.: CN202058323U, title: satellite positioning system comprehensive teaching platform) is open
A kind of satellite positioning system comprehensive teaching platform is opened comprising GPS principle, GPRS principle, antitheft detection and signal imitation four
Plate is sent out, four development boards are mutually indepedent and connect with platform board is linked, flat as the data mutually exchanged by link platform board
Platform is to realize each module being formed integral with one another functionally.Student can be allowed intuitively to observe and analyze single technology, introduction is learned
It is raw how to integrate each technology as a product.But the patent is only former from work of the angle of receiver user to GPS
Reason is demonstrated, and the teaching demonstration to entire GPS system, especially ground segment is lacked；Meanwhile the patent is mainly for GPS system
System, cannot achieve the teaching demonstration to other types global position system.In addition, comprehensive teaching platform described in the patent is hard
Part solidification, supports without background server, it cannot be guaranteed that timeliness that system version upgrading or teaching resource update and unique
Property.
Patent (Authorization Notice No.: CN205594167U, title: a kind of teaching of BDS/GPS Position Fixing Navigation System with open
Hair platform) it discloses and a kind of may be programmed SOC device, bus interface, inertial navigation mould entirely comprising BDS/GPS radio-frequency module, ZYNQ
The teaching and development platform of the BDS/GPS Position Fixing Navigation System of block, platform complete instructional function by presentation process, in conjunction with used
Property navigation module data and satellite positioning information complete inertia assisting navigation function, provided for User Exploitation inertia assisting navigation
Platform.The patent helps user to understand the process and principle of positioning, lacks to entire mainly for the positioning function of user segment
The teaching demonstration of navigation system, especially ground segment；Lack deployable experiment and its step introduction, is unfavorable for opening for experiment
Exhibition；In addition, there is also cannot be guaranteed system version upgrading or teaching resource update for teaching described in the patent and development platform
Timeliness and the Uniqueness.
In conclusion the shortcomings that existing satellite navigation teaching platform, is as follows:
1) for resource content mainly for receiver user, the positioning around receiver user carries out experimental implementation, lacks pair
The teaching demonstration of entire satellite navigation system operation logic；
2) part satellite navigation system is contained only in teaching platform, such as only includes GPS or including GPS+BDS, lacks four
The related content of courses under big Global Satellite Navigation System Coexistence Situation；
3) lack the teaching and experiment of Differential positioning in teaching platform, and Differential positioning is the master of current high accuracy positioning
Want mode；
4) existing teaching platform system upgrading or resource updates can only can just be known by CD or after logging in specific website
Whether dawn updates, and causes resource updates not in time, and more new version is inconvenient；
5) the matched resource content solidification of existing teaching platform, lacks background support, so that the scope of application is limited, property
Valence is relatively low；
6) experimental resources that existing teaching platform only has part single, lack principle knowledge matched with its or can be straight
The principle resource for giving lessons, and the code resource that support experiment is carried out are connect, the understanding after the completion of tested to knowledge point is caused
Time-consuming for still not thorough or experiment, it is more difficult to carry out；
7) existing teaching platform mainly relies on the satellite navigation data being collected in advance or emulation data, so that user
Theoretical level is remained in when carrying out experiment, it is not deep to the satellite navigation system understanding of real time execution.
