Abstract :
The modification of the longwave ASF (Additional Secondary Factor) is the key to ensure the precision of longwave navigation system, but at present there does not exist the effective way to measure the ASF, because of the effect of the geography. So the paper put forward the way that can measure the ASF, resulted from the theory of wavelet and least square, based on the integrated longwave and microwave navigation system. Meantime, the paper used the way to practical experiment, which proves it effective. And the usage of that method can combine our country navigation sources, improved the ability of our positioning.
