Abstract
Systems and methods for alerting surrounding aircraft if a ground-based unit is a threat. One example system is located on a ground-based unit. The system includes a position sensor that senses position of the ground-based unit, a memory that stores predefined threat zone information, a transmitter that transmits a predefined transponder signal, and a processor in data communication with the position sensor, the memory, and the transmitter. The processor instructs the transmitter to transmit the transponder signal based on the threat zone information and the sensed position of the ground-based unit.
Claims14
A transponder system located on a ground-based unit for alerting surrounding aircraft if the ground-based unit is a threat, the system comprising:
- a position sensor configured to sense position of the ground-based unit;
- a memory configured to store predefined threat zone information;
- a transmitter configured to transmit a predefined transponder signal;
- and
- a processor in data communication with the position sensor, the memory, and the transmitter, the processor configured to instruct the transmitter to transmit the transponder signal based on the threat zone information and the sensed position of the ground-based unit,
- wherein the transponder signal includes at least one of surface vehicle location, ground-based unit speed, direction of travel of the ground-based unit, or a unique identifier of the ground-based unit,
- wherein the transmitter is instructed to transmit a transponder signal if the processor determines that the speed and direction of travel indicate that the ground-based unit will enter a threat zone within a threshold period of time.

- and
- a processor in data communication with the position sensor, the memory, and the transmitter, the processor configured to instruct the transmitter to transmit the transponder signal based on the threat zone information and the sensed position of the ground-based unit,
- wherein the transponder signal includes at least one of ground-based unit location, ground-based unit speed, direction of travel of the ground-based unit, or a unique identifier of the ground-based unit,
- wherein the transmitter is instructed to discontinue transmission of a transponder signal if the processor determines that the speed and direction of travel indicate that the ground-based unit will exit a threat zone within a threshold period of time.
A method for alerting surrounding aircraft if the ground-based unit is a threat, the system comprising:
- sensing position of the ground-based unit;
- and
- instructing a transmitter to transmit a predefined transponder signal based on previously stored threat zone information and the sensed position of the ground-based unit,
- wherein the transponder signal includes at least one of ground-based unit location, ground-based unit speed, direction of travel of the ground-based unit, or a unique identifier of the ground-based unit,
- wherein instructing comprises instructing the transmitter to transmit a transponder signal if the processor determines that the speed and direction of travel indicate that the ground-based unit will enter a threat zone within a threshold period of time.
