高灵敏度GPS捕获技术研究综述
Review of Acquisition Techniques of High Sensitivity GPS
摘要
Abstract
The conception of acquisition techniques of high sensitivity GPS is introduced .According to the way of improving the sensitivity of GPS , the acquisition techniques of current high sensitivity GPS is classified into three modes , which are techniques of upgrading the SNR method ,cross-correlation interfer-ence mitigation method and assisted GPS acquisition method .On the basis of analyzing the methods of high sensitivity GPS modes , their features are compared and analyzed respectively .The development of techniques of high sensitivity GPS at home and on abroad are reviewed .The key technologies and future trend of high sensitivity GPS acquisition techniques are pointed .关键词
