Remote sensing involves the acquisition of information about the Earth's surface and atmosphere without direct contact. This is achieved through sensors mounted on #satellites, aircraft, or drones, which capture data across various wavelengths of the electromagnetic spectrum

Light detection and ranging (LIDAR) is used for weapon ranging, laser illuminated homing of projectiles, and to detect and measure the concentration of various chemicals in the atmosphere while airborne LIDAR can be used to measure the heights of objects. #Geography

We know that there are different ways to communicate, and the propagation of these waves can occur in different ways. Ground #Waves #propagation and skywave propagation are the two ways communication takes place for a certain distance.

#Spacecraft #propulsion is any method used to accelerate spacecraft and artificial satellites. In-space propulsion exclusively deals with propulsion systems used in the vacuum of space and should not be confused with space launch or atmospheric entry.

The #Signals propagates along the link, its power decreases because of fiber attenuation. Thus, most of the nonlinear effects occur early in the fiber span and diminish as the signal #propagates.

#Chromatica dispersion in digital communication systems induces distortion because the various spectral components of the pulse #propagate through the fiber at different #speeds, thereby arriving at the receiver with phase variations.

It is one of the #global #navigation satellite systems (GNSS) that provides #geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.

Radar #astronomy is a technique of observing nearby astronomical objects by reflecting radio waves or microwaves off target objects and analyzing their reflections. #Radar astronomy differs from radio astronomy in that the latter is a passive observation.

#Radar is a #radiolocation system that uses radio waves to determine the distance (ranging), angle (azimuth), and radial velocity of objects relative to the site. It is used to detect and track aircraft, ships, #spacecraft, guided missiles, and motor vehicles, and map weather.
