Abstract: Disclosed herein are a method and an apparatus of satellite positioning, the apparatus comprising a receiver module, a phase-difference measurement module, an angle-of-arrival calculation module, and a positioning module. The receiver module receives at a locale a first and a second signal from a satellite. The phase-difference measurement module measures the frequency of a phase difference of the signals along a geographic direction. The angle-of-arrival calculation module calculates the cosine of an angle of arrival of the signals for the geographic direction based on the frequency of the phase difference, the frequency difference of the signals, and a travelling speed of the satellite along that geographic direction. The positioning module calculates the coordinate of the locale along the geographic direction in the three-dimensional space based on that of the satellite, a distance between the satellite and the locale, and the cosine of the angle of arrival.

Abstract: A detached-type temperature indicator and method for using the same is disclosed. The indicator includes a temperature sensing module and a temperature display module. These two modules are separated apart with a distance, and the temperature change sensed by the temperature sensing module can be displayed on the separate temperature display module without using any power sources. This indicator is suitable for observing the magnetic sensing patterns which reflect the temperature variations within the package from the exterior of the package without opening the package. Also, this indicator may be used repeatedly.
