Abstract
An Integration method for RDSS/DNS is put forward. At first, positioning error of DNS is analyzed through computer simulation. It is found that the measurement error of yaw from AHS is the main error source of DNS. From this point, the possibility of integration for Passive RDSS/DNS without using the yaw data from AHS is discussed in condition that the height information can be obtained from barometer. Kalman filter is used to realize the integration. The model of the integrated system is described in detail. Computer simulation and flight-test are used to check the validity of the Integration. It is indicated that this kind of integration can greatly reduce the error emulation of DNS. The passive RDSS/DNS integrated system can not only give out more precise position but also has the character of high dynamic navigation performance. It greatly extends the passive applications of RDSS.
