The neutral densities at 130 km can be
derived fromtheMGS/RS measurements
with our method
The derived neutral densities can be
used to verify or calibrate the Martian
atmospheric model
The method can be applied to other
radio occultation measurements
such as MEX/RS measurements

Aircraft simulation platform is the most important supporting technology in the aircraft development process. This simulation platform can be used for validating the design of subsystem and also it provides the necessary data for the Aircraft design. Wind has great impact on the flight parameter. In order to accurately simulate the wind model and calculate the flight parameters
a simulation modeling method for flight parameter simulation platform under wind field environment is established. Firstly
the various sub-systems which affecting flight parameters are analyzed
some mathematical models of the flight parameter simulation platform is established. Secondly
the atmospheric wind field is studied to analyze the impact on its trajectory. Then the model is built in the Simulink toolbox in the Matlab which is based on the principles of hierarchy and modularity
using C MEX S-function for the complex kinetic equations. Finally
when the models have been established
encapsulating models for several subsystem and assembling them for the Aircraft simulation platform based on the unified interface. The simulation tests (including the performance test of a certain gliding Aircraft
the wind influence test of a certain uncontrolled aircraft) prove the simulation capability of the platform
and its calculating step can reach 1 ms. Comparing simulation with field test data of a certain uncontrolled aircraft
it shows that the relative deviation of range is 0.47%
the relative deviation of maximal altitude is 2.1%. Taking relevant standards as a reference standard
it is demonstrated the platform is reliable
meets the engineering accuracy requirements. 2010 IEEE.

To the design of an optoelectronic tracking servo system
we test the method [1
not only the reasonability of the control algorithm should be considered
2]. The simulation results verify the theoretical analysis. Because C MEX S function has the features of fast execute speed
but the cost and time as well. It is necessary to establish the simulation model for the system. Applying the C MEX S functions
independently generated program
we can build the every independent digital control modules in MATLAB/SIMULINK for the optoelectronic tracking servo system. In the paper
directly download to the hardwires
we apply the C MEX S function to the design of the practical optoelectronic tracking servo system. For the speed
we can design and debug the digital control modules in MATLAB/SIMULINK and then transform and download directly to DSP processor. 2010 IEEE.
