Abstract:
1. A satellite radiowave receiving device comprising: a receiving unit which receives a radiowave signal of a frequency band including a transmission frequency of a satellite signal transmitted on a radiowave from a positioning satellite; a conversion unit which converts the radiowave signal received by the receiving unit into digital data; a detection/arithmetic operation unit which performs a predetermined arithmetic operation to detect the satellite signal in a predetermined reception frequency from the digital data; a capturing unit which: a setting unit which sets: a specifying unit which: wherein the detection/arithmetic operation unit is configured to execute the predetermined arithmetic operation in parallel for the input signal data related to reception frequencies of which number is equal to or less than a predetermined number of maximum parallel processing, and the number of parallel processing is determined so that a total bit number of the data samples of which number is the number of parallel processing is equal to or less than the maximum bit number and equal to or less than the number of maximum processing.
