1. A signal receiving equipment comprising:
a receiver configured to receive signals from a GNSS satellite, a memory, and a processor configured to
select a plurality of signals from among the signals received by the receiver using a preset first parameter;
perform at least positioning of a location by code-based positioning using the plurality of signals selected using the first parameter;
select a plurality of signals from among the signals received by the receiver using a preset second parameter; and
perform positioning of a location and time synchronization by carrier-phase-based positioning using the plurality of signals selected using the second parameter, with coordinates indicated by the location positioned by the code-based positioning as initial coordinates,
wherein the processor is configured to execute the selection of the plurality of signals using the first parameter and the selection of the plurality of signals using the second parameter in parallel.
