INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract A consumption amount in a satellite signal receiver is estimated. The satellite signal receiver includes multiple control blocks including a front-end control block for receiving a satellite signal from a satellite and performing signal processing, a satellite capture control block for capturing the satellite signal, a satellite tracking control block for tracking the satellite signal, and a positioning control block for measuring a position of the satellite signal receiver on the basis of the satellite signal. A consumption information holding unit holds consumption information in which a first consumption amount is estimated in advance for each of the multiple control blocks. A consumption amount estimation unit estimates a second consumption amount in a predetermined period on a basis of the consumption information according to the operation state of each of the multiple control blocks within the predetermined period. ## Claims ### Claim 1 A consumption amount estimation device for a satellite signal receiver, comprising: a consumption information holding unit that holds consumption information in which a first consumption amount is estimated in advance for each of a plurality of control blocks in a satellite signal receiver that receives a satellite signal from a satellite and generates position information; and a consumption amount estimation unit that estimates a second consumption amount in a predetermined period on a basis of the consumption information according to an operation state of each of the plurality of control blocks within the predetermined period. ### Claim 2 (depends on 1) The consumption amount estimation device for a satellite signal receiver according to claim 1, wherein the plurality of control blocks includes a front-end control block for receiving the satellite signal and performing signal processing, and the consumption information includes the first consumption amount according to a height of an analog-to-digital conversion sampling frequency, a height of a clock frequency, or presence or absence of operation of a noise filter for each frequency band of the satellite signal. ### Claim 3 (depends on 1) The consumption amount estimation device for a satellite signal receiver according to claim 1, wherein the plurality of control blocks includes a satellite capture control block for capturing the satellite signal, and the consumption information includes the first consumption amount according to a number of satellites related to the satellite signal to be simultaneously captured, a height of a clock frequency, or a parameter for capturing the satellite signal. ### Claim 4 (depends on 1) The consumption amount estimation device for a satellite signal receiver according to claim 1, wherein the plurality of control blocks includes a satellite tracking control block for tracking the satellite signal, and the consumption information includes the first consumption amount for each channel according to a synchronization parameter for each of the satellite signals, a decoding state for each of the satellite signals, or a height of a clock frequency. ### Claim 5 (depends on 1) The consumption amount estimation device for a satellite signal receiver according to claim 1, wherein the plurality of control blocks includes a positioning control block for measuring a position of the satellite signal receiver on a basis of the satellite signal, and the consumption information includes the first consumption amount according to the number of satellites used to measure the position of the satellite signal receiver. ### Claim 6 (depends on 1) The consumption amount estimation device for a satellite signal receiver according to claim 1, wherein the first consumption amount is consumption current estimated in advance, and the second consumption amount is power consumption estimated during operation. ### Claim 7 (depends on 1) The consumption amount estimation device for a satellite signal receiver according to claim 1, wherein the consumption information includes the first consumption amount per processing time in the plurality of control blocks, and the consumption amount estimation unit estimates the second consumption amount on a basis of time required for processing in the plurality of control blocks. ### Claim 8 A satellite signal receiver comprising: a front-end control block configured to receive a satellite signal from a satellite and perform signal processing; a satellite capture control block configured to capture the satellite signal; a satellite tracking control block configured to track the satellite signal; a positioning control block configured to measure a position of a satellite signal receiver on a basis of the satellite signal; a consumption information holding unit that holds consumption information in which a first consumption amount is estimated in advance for each of a plurality of control blocks including the front-end control block, the satellite capture control block, the satellite tracking control block, and the positioning control block; and a consumption amount estimation unit that estimates a second consumption amount in a predetermined period on a basis of the consumption information according to an operation state of each of the plurality of control blocks within the predetermined period.
