What is the term for the component in a remote sensing system that physically carries the sensor?

• A. Sensor
• B. Platform
• C. Antenna
• D. Payload

Answer: (B)

The platform is the vehicle or structure that physically carries the sensor and provides the means to move and support it through space or air. In a drone or satellite system, the platform (the drone, spacecraft, or balloon) holds the sensor and holds any power, stabilization, and data links needed to operate the sensing equipment. The sensor is the instrument that detects or measures whatever you’re studying, while the antenna is part of the communications system, not the carrier. The payload refers to the equipment carried by the platform, which can include the sensor, but the item that physically carries the sensor is the platform.
