| Abstract: |
| TACAN data is often used to adjust the inertial navigation parameter
in which many sorts of coordinate transformation are concerned. Based on the adj
ustment features, this paper provides a series of coordinate transformation algo
rithm. It
s ultimate goal is to use the information of TACAN anti-azimuth and inclined dis
tance to calculate the object′s coordinate in WGS-84 system. The transformation
error is analysed in detail with Matlab simulation.The result shows the positio
ning precision after coordinate transformation satisfies the engineering applica
tion. |
