Modulation Methods

Compared to conventional navigation signal simulators, software simulator has many advantages, which include flexible design, easy extending, strong openness, and low cost. With the development of satellite navigation, satellite navigation system is getting more and more complicated. Based on the analysis for satellite navigation signal model in different modulation methods of multisystem, it is very urgent to establish a unified description method, which can reduce duplication writing of algorithm. firstly, description method for multisystem satellite navigation signal simulator is proposed. Secondly, it can describe different systems of satellite navigation signals and provide estimation method for signal transmission delay time and Doppler frequency shift. Finally, the signal of simulation is validated.

Specific Scenario

Satellite navigation has become a very important topic in the air transport industry along with its application in instrument approach procedures. Recently, extracted statistical characteristics of the European Geostationary Navigation Overlay Service (EGNOS) satellite signal have been made available from real measurements in the Czech Republic. The numerical modeling approach is taken for a feasibility study of automatic aircraft control during the Localizer Performance with Vertical Guidance (LPV) precision approach based on such navigation data. The model incorporates Kalman filtering of the stochastic navigation signal, feed-back control of L-410 aircraft dynamics and the calculation of approach progress along the predefined procedure. Evaluation of the performance of the system prototype is performed using the scenarios developed with a strong interest in altitude control. The specific scenario is focused on a curved approach which offers a huge advantage of the approaches based on the Satellite-based Augmentation System (SBAS) compared to ones with the Instrument Landing System (ILS). Outputs of simulation executions are statistically analyzed and assessed against predefined navigation performance goals equivalent to ILS categories with a positive outcome.
