uvm

This paper proposes a computation method for initial orbit determination and orbit improvement with ranging and range rate data at low angular measurement accuracy or unavailability of angular measurement data based on the ( Unit-Vector-Method ( UVM)) principle.

根据单位矢量法测轨原理，给出了在测角精度比较低或没有测角资料的情况下，利用测距、测速资料进行初轨和轨道改进的计算方法。

Because of changing the structure of UVM, we design the physical mapping and the management of kernel address space over again.

由于改变了UVM的结构，我们对物理映射和内核地址空间的管理作了重新设计。
