Remote Sensing e rm “ emote nsing” fers e The term remote sensing refers to the use of artificial devices, rather than our eyes, to observe or measure thingsfroma y, g distance without disturbing the intervening medium. Remote sensing enables us to observe & measure things on spatial, spectral, & temporal scales that otherwise would not be possible.

Advantages of Satellites tellite mote nsing rovides umber f vantages ver Satellite remote sensing provides a number of advantages over more traditional platforms (e.g. planes): Access to any location on the Earth irrespective of national boundaries and/or remoteness. Continuous operation for extended periods of time regardless f eather nditions r ason of weather conditions or season. A global perspective to measure cause and effect Regular revisit opportunities for change detection over time. Joseph Baker (ECE Dept) ECE 2984: Exploration of Space Lecture 21: Remote Sensing

Remote Sensing Mission pical acecraft mote nsing A typical spacecraft remote sensing mission includes five basic components: 1) An EM radiation source tmospheric teraction 2) Atmospheric interaction 3) A subject 4) A sensor formation k sers 5) Information link to users To observe a particular target on the ground the spacecraft needs to: oint e nsor e rget Point the sensor at the target.
