Abstract: An information processing device includes: a user information acquisition unit which acquires first information, second information, and third information about a user; a correlation information acquisition unit which acquires correlation information representing a relation between the first information, the second information, and the third information; an initial value setting unit which sets an initial value of the first information, the second information, and the third information; a fixing designation unit which designate fixing of the first information; a change designation unit which designates change of the second information; and an update unit which updates the third information on the basis of the correlation information.

Abstract: A coherent integration section synthesizes an IF signal stored in a memory and a C/A code replica generated by a code generation section using a mixer to calculate a correlation value, and integrates the correlation value using an integration section. An integration count monitoring section counts the integration count of the integration section. When a saturation control section has detected saturation of integration of the correlation values, the integration count monitoring section causes the integration section to suspend integration when the integration count is equal to or less than a reference count, and allows the integration section to continue integration when the integration count has exceeded the reference count.

Abstract: A positioning apparatus for receiving a positioning standard code which is used as a standard of positioning from a positioning satellite, comprising: analysis assistance code generating means for generating an analysis assistance code for determining which positioning satellite corresponds to the positioning standard code based on the received positioning standard code; positioning standard code identifying means for analyzing the positioning standard code and the analysis assistance code, and identifying which positioning satellite corresponds to the positioning standard code; and current position information generating means for generating current position information indicating a current position based on an identified result by the positioning standard code identifying means.

Abstract: A receiver receives and demodulates a transmission signal that is modulated in Phase Shift Keying modulation and Direct Sequence Spread Spectrum using a spread code. The receiver includes a signal receiving unit that receives the transmission signal and outputs a received signal; a filter unit through which the received signal outputted by the signal receiving unit passes and is outputted as an outputted signal; a base band unit that is configured to despread the outputted signal based on a corrected despread code. The corrected despread code is generated based on the spread code and a deformation position, the deformation position indicating a position in the spread code at which deformation occurs as a result of the received signal passing through the receiver filter unit.
