Abstract
A method of tracking a position of a transmitting apparatus in a sensor network is provided. The transmitting apparatus may receive Global Positioning System (GPS) information from each of satellites, may extract satellite time information and satellite identification information from the GPS information, may generate a transmission frame together with receiving time information and apparatus identification information, and may transmit the transmission frame to a receiving apparatus.
Claims20
A transmitting apparatus, comprising:
- a Global Positioning System (GPS) information processor to generate receiving time information based on a time at which GPS information is received;
- and
- a transmission frame generator to generate a transmission frame based on the receiving time information and the GPS information.
A position tracking method, comprising:
- generating receiving time information based on a time at which Global Positioning System (GPS) information is received;
- and
- generating a transmission frame based on the receiving time information and the GPS information.
A receiving apparatus, comprising:
- a frame receiver to demodulate a transmission frame received from a transmitting apparatus;
- and
- a position information generator to generate position information of the transmitting apparatus based on the transmission frame and Global Positioning System (GPS) information.
A position tracking method, comprising:
- demodulating a transmission frame received from a transmitting apparatus;
- and
- generating position information of the transmitting apparatus based on the transmission frame and Global Positioning System (GPS) information.
