Abstract:
Even if the propagation time interval of a sync signal is not constant, an accurate correction parameter is calculated, so that a corrected time point synchronized with a main clock device is obtained. A main transmission time point storage part stores respective main transmission time points at which a main device has transmitted a plurality of main sync signals and which are measured using a main clock device. A subordinate reception time point storage part stores respective subordinate reception time points at which a subordinate device has received the plurality of main sync signals and which are measured using a subordinate clock device. A speed ratio calculation part calculates a speed ratio of a ticking time speed of the main clock device to a ticking time speed of the subordinate clock device, based on a main transmission mean time point being a mean of the main transmission time points and a subordinate reception mean time point being a mean of the subordinate reception time points.

Claim (Index 2):
A subordinate device for use with a correction parameter calculation device which includes\n a main transmission time point memory that stores main transmission time points at which a main device has transmitted a plurality of main sync signals and which are measured using a main clock; a subordinate reception time point memory that stores subordinate reception time points at which the subordinate device has received the plurality of main sync signals and which are measured using a subordinate clock; and speed ratio calculation circuitry that calculates a speed ratio of a ticking time speed of the main clock to a ticking time speed of the subordinate clock, based on a main transmission mean time point being a mean of the main transmission time points and a subordinate reception mean time point being a mean of the subordinate reception time points, the subordinate device comprising: a subordinate clock that measures a time point, a subordinate receiver that receives the main sync signal a plurality of times, and subordinate reception time point measuring circuitry that measures, as the subordinate reception time points, time points at which the subordinate receiver has received the main sync signal, using the subordinate clock; and synchronized time point calculation circuitry that calculates a corrected time point synchronized with the time point of the main clock, by correcting the time point measured by the subordinate clock based on the speed ratio.
