Research output: Contribution to conferencePaperpeer-review


At present, we can measure within several centimeters by high performance GPS. But the system requires a lot of money for its infrastructure. We paid attention the weighted matrix of least-squares method in SPS. We proposed the new weighted matrix, it is calculated by "dr". We aimed at compensation of positioning by using the new matrix. We could improve SPS precision and accuracy.
