Beidou/GNSS (Global Navigation Satellite System) satellite navigation teaching and experiment cloud platform

Abstract

The invention discloses a Beidou / GNSS (Global Navigation Satellite System) satellite navigation teaching and experiment cloud platform, which comprises a client, disposed in the local place of a user;a mobile terminal, disposed in the open air and configured to acquire differential data and upload the differential data to a server end through an Internet; and a server end, connected with the mobile terminal and the client through an Internet, wherein the client uses teaching and scientific research resources and data resources of the server end and uploads local resources; the data acquired by the mobile terminal are stored in a differential server of the server end for use by the client. The Beidou / GNSS satellite navigation teaching and experiment cloud platform has the advantages of convenience in operation, high integration degree, good effect and the like.

Description

technical field [0001] The present invention mainly relates to the field of satellite navigation teaching experiment equipment, in particular to a Beidou / GNSS satellite navigation teaching and experiment cloud platform. Background technique [0002] GNSS is the abbreviation of Global Navigation Satellite System (Global Navigation Satellite System), which generally consists of three parts: the space segment, the ground segment and the user segment. GNSS provides all-weather, continuous and accurate position, velocity and time information for any location on Earth and near-Earth space. At present, the global satellite navigation system mainly includes China's Beidou-3 (referred to as BDS), the US GPS system, Russia's GLONASS system and Europe's Galileo system. The service scope of these systems covers the whole world, thus forming the world's four major satellite navigation systems. [0003] Since my country's Beidou-2 regional satellite navigation system was launched at the...

AI Technical Summary

Problems solved by technology

[0008] 1) The resource content is mainly aimed at the user receiver, and the experimental operation is carried out around the positioning of the user receiver, and there is a lack of teaching demonstration of the operating principle of the entire satellite navigation system;

[0009] 2) The teaching platform only includes some satellite navigation systems, such as GPS or GPS+BDS, and lacks the relevant teaching content under the coexistence of four global satellite navigation systems;

[0010] 3) There is a lack of teaching and experimentation of differential positioning in the teaching platform, and differential positioning is the main way of high-precision positioning at present;

[0011] 4) The existing teaching platform system upgrade or resource update can only be known whether it is updated through the CD or after logging in to a specific website, resulting in untimely resource updates and inconvenient update versions;

[0012] 5) The resource content of the existing teaching platform is solidified and lacks background support, which limits the scope of application and lower cost performance;

[0013] 6) The existing teaching platform only has some single experimental resources, and lacks the supporting principle knowledge or the principle resources that can be directly used in teaching, as well as the code resources that support the experiment development, resulting in incomplete understanding of the knowledge points after the experiment is completed Or the experiment takes a long time and is difficult to carry out;

[0014] 7) The existing teaching platform mainly relies on the satellite navigation data or simulation data collected in advance, so that users still stay at the theoretical level when carrying out experiments, and do not have a deep understanding of the real-time satellite navigation system
