Following constantly development of informationization level, the aircraft flying control missions will happen remarkably changes, so the control system will adopt the united flying control pattern based on autonomous sensor information and co-information. This paper introduces one kind of hardware-in-the-loop simulation system of informationization flying control. The developing requirements about...
In pervasive computing, the computer is no longer a single computing device, but an information device with the embedded processor, memory, communication module and various sensors together. This paper puts forward an algorithm to improve precision of navigation for space aircraft based on time compensation. The algorithm involves two-body movement time to correct the oblate ness perturbation flying...
The paper involves one kind of mobile autonomous running system for pervasive computing. The developing requirements about aircraft flying control system of informationization were firstly analyzed, then the architecture on aircraft flying control system of informationization based on pervasive computing was presented. Lastly the design conception and its accuracy were verified by principle prototypes.
The approach combines both Chan's algorithm and another close-form algorithm to solve the aircraft multilateration surveillance equations. Results developed are applicable for the surveillance system as a final location solution or as an initial one for the iteration algorithm. However, the ambiguous problem occurs if there are only three TOA measurements. So, the approach will also focus on it and...
Conflict detection and resolution (CDR) is one of the key points for the civil aviation safety. State estimation and trajectory prediction are important components of a CDR system. This paper proposes a new algorithm to accomplish these tasks. For state estimation, the Kalman filter is used to provide accurate continuous state estimates and an adaptive model-transition protocol is introduced to track...
A new method, IAADO (Information-Aided Anti-Doppler-Offset), aiming at eliminating ICI (Inter-Channel-Interference) caused by DFO (Doppler Frequency Offset) and improving the performance of AMBC (Aviation Mobile Broadband Communication), is presented with a view to the characteristics of the high DFO of aviation channel and the aircraft as a platform of AMBC. The strong ICI caused by large DFO, degrades...
