In some circumstances GPS receivers can receive only incontinuous or partial satellite signals,it's still an open issue how to measure velocity and calculate location with partial GPS signals.

在某些特定的应用情况下，GPS接收机接收到的信号是非连续，或者是间段瞬时的。如何合理有效地利用间段的瞬时GPS信号进行定位、测速是个很有意义的课题。

Methods: Using the techniques of cell culture ex vivo, flow-cytometry, immunocytochemistry, the effects of GPS on the proliferation of human promyelocytic leukemia cell line(HL-60) and human granulocytopoiesis and monocytopoiesis were observed.

结果：GPS在体外能抑制HL-60细胞增殖，而同等剂量的GPS能明显促进正常粒单系造血祖细胞的增殖分化；在本实验条件下未见GPS对HL-60细胞有明显的诱导分化作用。

It is stated that multipath is closely related with observation environment and receiver performance. In more detail, receiver is classified as coherent delay loop and noncoherent delay loop by its operation. Their tracking properties for GPS signals are determined by discriminator curve.

GPS 中的多路径效应是在一定的观测环境下产生的，不同的 GPS 接收机所受到的多路径效应影响也有所不同，因此，除观测环境外， GPS 接收机内部工作机理与多路径效应的产生是密不可分的。

Toll Collect's on-board units use GPS to determine a truck's position. To compensate for the technology's weaknesses—it can only determine the truck's position to within a few metres—the device compares the GPS data with information from the tachograph and a built-in gyroscope.

公路收费的车载单元使用GPS确定卡车位置，为弥补技术上的缺陷（在确定卡车位置时会存在几米的误差），设备将GPS上的数据与计速器和一个内置陀螺仪上的数据对比。

Reference frame's uniformation methods, adjustment methods and the implication of corresponding datum for various adjustment methods are systematically discussed about high precision GPS network. The systematical investigates on the choice of reference station in the high precision GPS data processing and the effect to adjustment results are made. Some general principles on the choice of reference station are presented.
