摘要： A variable gain amplification circuit can increase a dynamic range without increasing an offset voltage. The variable gain amplification circuit amplifies an input signal by a desired gain. An amplification circuit amplifies the input signal by a predetermined gain based on a bias current. A bias current control circuit controls the bias current based on a level of the input signal. The bias current supplied to the amplification circuit can be reduced when there is no input signal, and the bias current increases as the level of the input signal increases. Thus, an offset voltage can be decreased while a sufficient dynamic range is maintained.

摘要： Relative vector between an observation receiver located at an object and a reference receiver are divided into long period variation components not dependent on object displacements and short period variation components dependent on object displacements, and the short period variation component are represented by x, y and z axis components of unit vectors from the reference receiver toward the satellite. Then, carrier phases between at least three GPS satellites and the receivers are measured, and these measurement data are passed through a band pass filter to extract short period phase components corresponding to the short period variation components of the relative vectors. Next, at least three receiver to receiver single differences between the receivers and the GPS satellites are found for the short period phase components, and axial components of the short period variation components of the relative vectors are found by computation based on said at least three receiver to receiver single differences.
