Abstract: The present invention relates to a global positioning system (GPS) signal acquisition system and a method thereof and, more specifically, to a one-dimensional GPS signal acquisition system with low complexity for acquiring a carrier phase using a multi-stage partial cross-correlator after acquiring an accurate code phase through a code phase acquisition process with a Delay-Multiply technique. According to the present invention, a proposed carrier phase acquisition structure operates after acquiring the accurate code phase accurately using the Delay-Multiply technique which is resistant to carrier phase errors in an acquisition process of the one-dimensional GPS signal, wherein the maximum size of the allowable carrier phase errors is 50 kHz.

Abstract: A manufacturing method of a micro silicon reflector having a plurality of orthogonal reflecting surfaces is provided to obtain a high reflectance by depositing a metallic thin film for improving the reflectance on the orthogonal reflecting surfaces. Layers for forming masks are formed on upper and lower surfaces of a silicon wafer substrate. Mask patterns are formed on the layers. The silicon wafer substrate having the mask patterns is etched in a wet-etch manner. A vertical protrusion having mirror surfaces is formed vertically along a crystalline surface of the silicon wafer substrate. A metallic thin film is deposited on each of the mirror surfaces in order to improve a reflectance of the mirror surface of the vertical protrusion. The silicon wafer having the vertical protrusion is cut in a predetermined width with respect to the longitudinal direction of the protrusion. A cutting process is performed to cut both ends of a plurality of cross orthogonal structures. A cross-orthogonal type vertical reflector is obtained.

Abstract: A scanning system of a wireless optical sensor network is provided to obtain high energy efficiency by using a pattern which reversely reflects a light source by using a sensor node including an orthogonal reverse reflector. A wireless optical sensor network system includes a light source(102), a scanning mirror, at least one sensor node(108,110), a beam splitter(104) and a synchronization unit(100). The scanning mirror is formed to be rotary at a constant angle on an advance path of an optical signal, and adjusts the advance path of the optical signal by reflecting the optical signal. At least one sensor node reflects an optical signal reflected from the scanning mirror, and the beam splitter passes or reflects the optical signal reflected from the sensor node.
