Abstract

An execution method of a position calculating circuit that calculates a position by receiving a satellite signal transmitted from a positioning satellite and that has an externally readable storage section includes: receiving a selection signal for selecting acquired information, which is information acquired from information obtained from the satellite signal, from the outside; selecting the acquired information on the basis of the selection signal; and storing the acquired information in the storage section and outputting a notice signal, which indicates that the acquired information has been obtained, when the acquired information selected from the satellite signal being received is obtained.

What is claimed is: 
     
         1 . An execution method of a position calculating circuit that calculates a position by receiving a satellite signal transmitted from a positioning satellite and that has an externally readable storage section, the execution method comprising:
 receiving a selection signal for selecting acquired information, which is information acquired from information obtained from the satellite signal, from the outside;   selecting the acquired information on the basis of the selection signal; and   storing the acquired information in the storage section and outputting a notice signal, which indicates that the acquired information has been obtained, when the acquired information selected from the satellite signal being received is obtained.   
     
     
         2 . The execution method according to  claim 1 , further comprising:
 outputting a periodic signal to the outside at predetermined intervals synchronized with time information, which is included in the information obtained from the satellite signal, when the acquired information is the time information and the time information is obtained from the satellite signal being received.   
     
     
         3 . The execution method according to  claim 1 ,
 wherein the information obtained from the satellite signal includes time information and position information,   when the acquired information is the position information, position calculation processing is executed in which the position is calculated by acquiring the time information from the satellite signal and calculating a pseudo distance, and   position information, which indicates the position calculated by the position calculation processing, and time information, which is calculated during the execution of the position calculation processing, are stored in the storage section.   
     
     
         4 . A position calculating circuit that calculates a position by receiving a satellite signal transmitted from a positioning satellite, comprising:
 an externally readable storage section;   a selection section that receives a selection signal for selecting acquired information, which is information acquired from information obtained from the satellite signal, from the outside and selects the acquired information; and   a storage control section that stores the acquired information in the storage section when the acquired information selected from the satellite signal being received is obtained.   
     
     
         5 . A host device that controls an operation of the position calculating circuit according to  claim 4 , comprising:
 a selection signal output section that generates the selection signal on the basis of a user's selection operation and outputs the selection signal to the position calculating circuit;   a determination section that determines whether or not the acquired information is stored in the storage section; and   a reading section that reads the acquired information from the storage section when the determination section determines that the acquired information is stored in the storage section.
