| Summary: | 碩士 === 國立臺灣大學 === 電機工程學系 === 86 === In this thesis, we conduct a simulation to study
the application of Global Positioning System (GPS) on aero-navigation.
Our simulation considers the total number, the Horizontal Dilution of
Precision (HDOP) and the Vertical Dilution of Precision (VDOP) of the
satellites in one day over the eight airports in Taiwan.
When applying the GPS on navigation, we use the positioning
method of Difference GPS (DGPS). It is not suitable on aero-navigation,
because the noise of DGPS will result in the violent variation of
position. Therefore we use the method of Carrier Smoothed Code (CSC) to
improve the violent variation of position
On the other hand, we also discuss that when the cycle slip happens,
it inevitably will cause the situation of violent variation of positioning
due to reset of CSC.To resolve the problem, we use Kalman Filter
as Step Filter to prevent the violent variation of positioning.
