    • PROBLEM TO BE SOLVED: To provide accurate time information used for acquisition of a signal to a signal receiver. SOLUTION: A global positioning system (GPS) system includes a clock module for providing multiple counter values at multiple time points. The GPS system also includes a system module coupled to the clock module. The system module is capable of obtaining a time value for each time point according to a set of signals from a signal source. The system module is further capable of calculating a set of parameters based on the counter values and the time value for each time point, and determining an estimated time value based on the parameters and a present counter value from the clock module.

    • PROBLEM TO BE SOLVED: To provide a GPS wave height, current direction and current speed measuring device and a system using it, enabling correct measurement for wave height (height of wave) and current direction and speed (current of tide) at an arbitrary spot on the sea or a lake with GPS. SOLUTION: The GPS receiver 2 of GPS wave height, current direction and current speed measuring device 1 processes a GPS signal received by a GPS antenna 3 to measure the three-dimensional position of the antenna 3. The three-dimensional position data is recorded in a data recorder 4 connected to the GPS receiver 2. A floating body 5 is loaded with the respective devices 2 to 4, and floats on the sea to be moved according to the current of wave and tide on the spot. A data processor 6 is loaded with software 7 for performing high-pass filtering and smoothing and outputs data on the wave height and current direction and current speed while eliminating an error from the three-dimensional data recorded by the data recorder 4.
