The clock frequency abnormal state make a direct impact of signal integrity monitoring. The theoretical analysis and software simulation are the commonly way to studying on the abnormal state clock frequency signal and it's impact for GNSS system applications. In order to test and evaluate this impact, The paper designs and implements navigation clock abnormal state impersonation system. And it designs a clock abnormal impersonation emulator, based on the simulation software Mat lab and the Programmable DC Power Analyzer Agilent N6705 and high-precision adjustable bias voltage of Voltage Controlled X'tal Oscillator (VCXO). Firstly, through the Mat lab simulation to generate a specific pattern of tiny voltage control words, a particular feature of the control voltage generated by the programmable DC power analyzer, adjust the controllable bias voltage of VCXO, then the corresponding micro-controllable variation state superimposed on the main clock, so that the clock contains various abnormal state, at last using Frequency Counter SR620 to measure the output of the system to analyze the results. The simulation and experimental results show that the system can correctly emulate the output frequency clock rate of the abnormal state, including white-noise characteristics of the variable amplitude fluctuations. Furthermore the size, duration, amplitude of the above-mentioned characteristics can be controlled adjustable. The clock abnormal state impersonation emulator can be widely used in the testing and emulating of abnormal clock frequency signal for GNSS system.","PeriodicalId":360796,"journal":{"name":"2013 Third International Conference on Instrumentation, Measurement, Computer, Communication and Control","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128142606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But the filters in the last cascade of reviver's analog circuits are primary causes of non-ideal channel characteristics so that group delay equalization is efficient and necessary. Narrowband group delay equalization, which can't satisfy wideband filter, has been improved to a wideband group delay equalization of satellite navigation receiver. The thesis analyzes and designs a high-order equalization based on Centro Symmetric Equalization Method. By simulating and producing actual circuit, the performance of third-order and fifth-order group delay equalization networks are compared and analyzed. Finally, the fifth-order wideband group delay equalization circuit is cascaded with the filter of navigation receiver that the maximum group delay of pass band has been reduced to 5 ns between full bandwidth, 10% of before. This method has been applied on a wideband high measurement accuracy anti-jamming navigation receiver and improved the group delay characteristics from the analog frond-end.","PeriodicalId":360796,"journal":{"name":"2013 Third International Conference on Instrumentation, Measurement, Computer, Communication and Control","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131045780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
