In the broadest sense, remote sensing is the measurement or acquisition of information of an object or phenomenon, by a recording device that is not in physical or intimate contact with the object. In practice, remote sensing is the utilization at a distance (as from aircraft, spacecraft, satellite, or ship) of any device for gathering information about the environment. Thus an aircraft taking photographs, Earth observation and weather satellites, monitoring of a fetus in the womb via ultrasound, and space probes are all examples of remote sensing. In modern usage, the term generally refers to techniques involving the use of instruments aboard aircraft and spacecraft, and is distinct from other imaging-related fields such as medical imaging or photogrammetry.

Main deference is the distance. Remote could mean many things. 1. Automatic. 2. Unmanned. 3. Isolated as in remote areas like deserts, oceans, mountains. Remote tracking/sensing of prisoners on house arrest. Satellite sensing: When sensing is done using sensors on satellite. Sensing is done using Satellite. I believe there are 11 satellites that covers the world and take pictures every few minutes. There are other types of sensors on satellite that do various other things, major public use is in TV and Telecommunication.

A satellite with remote sensors to observe the earth is called a remote sensing satellite or earth observation satellite. Meteorological satellites are sometimes discriminated from the other remote sensing satellites.
Remote sensing satellites are characterized by their altitude, orbit and sensors. The main purpose of the geosynchronous meteorological satellite (GMS) with an altitude of 36,000 km is meteorological observations, while Landsat with an altitude of about 700 km, in a polar orbit, is mainly for land area observation.
NOAA AVHRR with an altitude of 850 km in a polar orbit is mainly designed for meteorological observation but is also successfully used for vegetation monitoring.
In future some remote sensing satellites will have large payloads with many kinds of multi-purpose sensors, such as the polar orbit platform (POP) project under the international cooperation of US, EEC, Japan and Canada. As well, there will be more specialized missions using small satellites..

Remote Sensing satellites are the sun synchronous a that in are put in orbit above earth roughly 900 KM . they rotate around the earth and start clicking the photograph. In Indian context the Remote sending satellites are IRS series , cartosat series. The resolution that is clarity of the image depends on the sensors i.e. cameras of the same.

Remote Sensing Satellites are special purpose satellites launched into space for the task of constantly supplying information back to Earth to a control tower machine regarding the changing details of the Earth's atmosphere
Their applications range from detection of changes in the objects of outer space to assisting scientists on earth in the process of guiding Unmanned space missions.
Such satellites are also used by the Military and Air Force for detection of warplanes

Remote Sensing satellites are artificial sent through earth .Remote sensing refers to taking informationwithout physical contact with that body . The orbits dedicated to remote sensing are such that the position of sun in respct to earth when satellite passses through it .It is used to in forest surveys , ground water surveys etc.

these r those satellites which senses the various activities at remote areas like spying, weather conditions. it is the one which tells us about the valcano eruptions and the tsunami like weather.
