This paper introduces two methods to get the virtual sensor signal of angle of attack and sideslip angle: Nonlinear Observer method and INS/GPS method.

本文介绍了两种方法来得到迎角和侧滑角的虚拟传感器信号：非线性观测器方法和利用INS／GPS系统数据估计迎角和侧滑角方法。

The fault-tolerant problem for INS/GPS integrated system is studied, and a two-level scheme fcsr failure detection and isolation is proposed.

本文研究了INS/GPS组合导航系统的容错问题，并提出了一个两级故障检测及分离方案。

Since the INS/GPS does not meet the need of imaging, Doppler parameters are obtained from SAR raw data to compensate the motion error.

由于INS/GPS数据难以满足成像精度要求，从回波数据中提取运动参数，用于运动补偿。

Just as photos on camera phones needed Instagram's filters for their distribution to grow, and GPS chips went from preventing you from getting lost to Foursquare's social check-ins, so the physiological signals that are currently generating charts, graphs and analysis will eventually be moulded into more social experiences, he argues.
