So far, the Beidou Short Message Simulator with the most comprehensive business functions and the highest technological maturity covers regional and global short message communication, as well as RDSS positioning and testing capabilities.
RTS9000 is a Beidou RDSS satellite signal simulator for global applications, supporting the transmission of S-band outbound signals for regional short messages and the reception and calculation of L-band inbound signals. It has the B2b downlink signal simulation and L-band inbound signal reception capabilities required for Beidou-3 global short message communication, position reporting, and emergency search and rescue functions.
The RTS9000 closed-loop testing system has functions such as outbound signal transmission, inbound signal reception and processing, and user equipment data interface. It has the ability to identify, finalize, and authenticate various RDSS user equipment, such as handheld, vehicular, and command type user machines. It supports the Beidou No.2 RDSS, Beidou No.3 RDSS, Global Short Message Signal System, and User Equipment Interface Protocol.
迄今為止，業(yè)務(wù)功能最全面、技術(shù)成熟度最高的北斗短報文模擬器，覆蓋區(qū)域+全球短報文通信、RDSS定位測試能力。
The scripted editing ability of the testing plan planning function and testing process allows users to plan and design the testing plan according to the testing requirements before the experiment, and edit the testing process. Users can manage and configure the testing scenarios and processes according to the testing needs of different receivers and different testing tasks and objectives, and use them as different testing templates.
Perform manual or batch Test automation based on test scenarios and test processes, and have one click Test automation function for user terminal technical indicators.
After each test project is completed, it can automatically analyze and evaluate the test data and generate test reports, with the function of automatic analysis and evaluation of user terminal technical indicators.
Multiple testing and evaluation modes are available, including automatic, manual, and single mode.
Real time analysis and evaluation of test data, capable of analyzing and comparing test data in real time, completing functional and performance indicators such as pseudo range measurement accuracy, positioning accuracy, channel consistency, bit error rate, etc., and automatically generating data processing reports.
The real-time analysis and evaluation function of test data allows for knowing the statistical results of indicators without waiting until the end of the test, facilitating the timely termination of problematic receiver tests and saving testing time.
Comprehensive display function: It can comprehensively display various information such as work status, simulation scenarios, positioning results, data processing reports, etc. in various forms such as data, tables, graphics, etc.
Database management function, which can automatically classify, store, query, and count simulation and test data, and has automatic data storage and retrieval functions.
Equipped with automatic evaluation of test results and automatic generation, printing, and export of test reports.迄今為止，業(yè)務(wù)功能最全面、技術(shù)成熟度最高的北斗短報文模擬器，覆蓋區(qū)域+全球短報文通信、RDSS定位測試能力。
