Accuracy Test and Pass Criteria of Beidou-Ⅲ Airborne Equipment for Civil Aviation
摘要
Abstract
Civil aviation has very high requirements for safety and integrity,and the accuracy test methods and pass criteria are critical to airborne equipment based on aircraft-based augmentation system and satellite-based augmentation systems,especially when subjected to external radio frequency interference.The Radio Technical Commission for Aeronautics Special Committee 159 has developed the test methods of aviation equipment from the traditional position-domain to the range-domain,and the CTSO-2C609 standard for independent BDS airborne navigation equipment directly quotes the test requirements and methods of"measurement accuracy Test"and"24-hour actual satellite accuracy test"in the GPS airborne standard.For the direct quotations in CTSO-2C609 standard,detailed analysis and demonstration are made for the accuracy test methods and pass criteria,a more accurate"110％passing threshold"set is given,and finally the verification is proceeded through interference experiments and real data from International GNSS Service stations.The conclusion shows that the"measurement accuracy"and"24-hour actual satellite accuracy"are better than the"110％passing threshold"of 1.0776 when the number of independent samples is more than 2 000.The analyzing and demonstrating process and the new"110％passing threshold"parameter provide support for the preparation or upgrading of Beidou airborne equipment aviation standards.关键词
