Research On Authentication Test System Of BDS Application Product

Beidou applications have a wide variety of product forms,which combines satellite navigation,mobile communication,mobile Internet,digital maps,surveying and mapping and other technologies.As the only connection between the users and the Beidou navigation satellite system(BDS),BDS application products’ performance of the pros and cons,quality of high and low,safe or not have a direct impact on the interests of the majority of users and consumers,on the security of its industry,and on the industrialization process of BDS,even the uplink transmission performance of RDSS can affect the system’s operation safety.Authentication is an universal means of international,which is used to consider the level of product quality and the capacity of manufacturing enterprises.From the perspective of product testing,authentication test focused on testing the product’s overall performance and functionality,it’s more accurate,comprehensive and reliable compared with the general inspection or testing.The purpose of this paper is to study and build a powerful and advanced authentication test system,which will meet the requirements of Beidou satellite navigation products authentication system,cover multi-system and multi-frequency,and have capabilities of batch testing 40 products.The input of this system designing combines the practical work demands with previous experience in system design and authentication test to develop the Beidou satellite application product authentication test system,which can provide a one-stop authentication solutions for multi-system chips,modules,OEM board,terminals and antennas of BDS RNSS,RDSS,GPS,GLONASS and Galileo systems.This paper firstly introduces the development and current situation of the global major satellite navigation systems and test systems,describes the progress of the BDS application products,and proposes the overall architecture of the authentication systems for BDS application products creatively,and respectively presents the components of organization systems,the institution and the file systems.To support the construction of BDS application products authentication system for starting point,I have cleared the overall composition of the authentication test system,it includes test and evaluation software,navigation signal simulator,digital simulation software,inboard signal processing unit,the outboard RF signal distribution network,wireless and cable test environment.I present the performance requirements and each subsystem design goals,and describe the detailed design program of the system implement,and design the user interface and report templates for each level.Finally,I take the test of BDS dual-mode type standard vehicle terminal to verify that the performance and functionality of the BDS application product authentication test system is satisfactory.At present,this system has gained good application for authentication of BDS application products.
