摘要
A ground control point device includes an SAR wave reflector configured to receive an SAR wave incident from an SAR in an incident direction and to reflect the SAR wave in the incident direction; a GNSS receiver configured to receive a GNSS wave to generate, based on the GNSS wave, time information and positional information indicative of a position of a control point; an SAR wave receiver configured to receive the SAR wave; and a control point data generator/transmitter configured to generate control point data obtained by associating the positional information when the SAR receiver receives the SAR wave with a time instant of reception of the SAR wave that is determined based on the time information, and to transmit the control point data to outside.
