The platforms that harbor remote sensing sensors (eg. cameras) are called remote sensing platforms. In earlier days, during military reconnaissance, pigeons attached with cameras were made to fly over areas of interest. In this case the platform is the bird. Balloons, airplanes and satellites that carry remote sensing sensors are examples of remote sensing platforms.

Remote Sensing Center was created in 2006-09.
Passive remote sensing means that the energy being collected is being provided by the environment in which you are collecting. Examples of this type of remote sensing include things as simple as taking a picture with a handheld visible spectrum camera or taking a thermal image of a person's body temperature. Active remote sensing on the other hand involves transmitting energy, allowing that energy to reflect off of the surrounding environment, and then recollecting that energy using a sensor. Examples of this type of remote sensing include sonar devices used by ships and imaging systems that use the returns from laser energy to form an image.

Pakistan Remote Sensing Satellite was created in 2011.
Indian Institute of Remote Sensing was created in 1966.
Explain how the remote sensing satellites examined the earth from the space?
What are some non-satellite remote sensing technology?
A mapmaker might use active remote sensing over passive remote sensing because active remote sensing provides its own source of energy to illuminate the target, allowing for more control over the data collected. This can result in better resolution and accuracy in mapping features of interest.
Active remote sensing uses its own electromagnetic radiation and use microwaves. It maps areas hard to map.
Optical remote sensing is affected by cloud covers , rain etc but microwave remote sensing is not.However the optical sensors always need sun as a source of illumination while active microwave sensors don't need.
