Abstract
A system for transmitting time-synchronized signals for positioning is provided. The system for transmitting positioning signals includes a transmitting apparatus mounted on artificial satellite, a repeater mounted on an artificial satellite, and a repeater mounted on an artificial satellite. Positional relation among artificial satellites is specified beforehand. Transmitting apparatus transmits a signal generated by encoding using a code identifying itself. Repeater receives a signal from the transmitting apparatus and transmits the signal. Repeater receives a signal from the transmitting apparatus and transmits the signal. The signals transmitted from the transmitting apparatus and repeaters and are received by receiving apparatuses and having the function of receiving the signals.
