The sensor used in the satellite remote sensing is
The sensor used in the satellite remote sensing is
Show Hint
Remote sensing sensors are broadly grouped into photographic sensors (cameras using film) and non-photographic sensors (electro optical scanners and detectors that record energy as digital signals).
Updated On: Jun 16, 2026
- Photographic sensor
- Non-photographic sensor
- UV sensor
- Infrared sensor
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Remote sensing sensors are broadly grouped into photographic sensors (cameras using film) and non-photographic sensors (electro optical scanners and detectors that record energy as digital signals).
Step 1:
Satellites cannot conveniently use film based photographic cameras that need physical recovery; instead they use electronic detectors that scan the scene and transmit digital data to ground stations. These are non-photographic sensors.
Step 2:
UV and infrared sensors describe only particular spectral bands and are specific types, whereas the general category of sensors carried on remote sensing satellites is the non-photographic (electro optical) sensor.
Answer: Option (2) — Non-photographic sensor.
