Abstract

The rapid evolution of inertial Micro-Electro-Mechanical System (MEMS) sensors offers the opportunity to replace expensive conventional Air Data Inertial Reference Units (ADIRU) in future aircraft navigation systems. Particularly with the advent of modernized GNSS and multi-constellation systems, the expected performances of future GNSS-aided Attitude and Heading Reference Systems (G-AHRS) are supposed to satisfy the current requirements. Since MEMS exhibit limitations in their accuracy nowadays, detailed investigations are needed to evaluate the possibility of using them within G-AHRS and also for navigation in the short, mid or long term. This papers deals with the usability of MEMS sensors with current and expected future performance. This evaluation was done based on real flight test data and simulation of future MEMS sensors. While current MEMS cannot completely fulfill all needed requirements, future sensors are expected to satisfy them.

商用飞机和公务机的MEMS INS/GNSS杂交分析与评价

惯性微机电系统(MEMS)传感器的快速发展为在未来的飞机导航系统中取代昂贵的传统空气数据惯性参考单元(ADIRU)提供了机会。特别是随着现代化GNSS和多星座系统的出现，未来GNSS辅助姿态和航向参考系统(G-AHRS)的预期性能应该满足当前的要求。由于MEMS目前在精度方面存在局限性，因此需要进行详细的调查，以评估在G-AHRS中使用它们以及在短期，中期或长期导航中的可能性。本文讨论了MEMS传感器的可用性，以及当前和预期的未来性能。该评估是基于真实飞行试验数据和未来MEMS传感器的仿真进行的。虽然目前的MEMS不能完全满足所有需要的要求，但未来的传感器有望满足这些要求。
