| Abstract: | Using the STK satellite database, the GPS satellite constellation is established.Then use the Galileo orbit parameter for simulating the Galileo satellite constellation and DOP, compares the visible satellite number and DOP between GPS and Galileo system, at same time and same place Wuhan.Also the whole world DOP distribution was depictured.The result indicates that Galileo constellation is better than GPS.And simulates GPS and Galileo combined constellation , more visible satellite brings diminished DOP , ... |
