What remote sensing devices uses a system of 27 satellites that transmit microwaves?
The remote sensing device that uses a system of 27 satellites transmitting microwaves is the Global Positioning System (GPS). These satellites orbit the Earth and provide location and timing information to GPS receivers on the ground. By analyzing the microwave signals received from multiple satellites, GPS receivers can calculate precise positions anywhere on Earth.
What else can I help you with?
Way of collecting information from a distance with satellite or other devices?
remote sensing
How can a satellite see through clouds?
Satellites can see through clouds using active microwave remote sensing technology. Microwaves can penetrate clouds, allowing satellites to observe Earth's surface even when it is obscured by clouds. By measuring the microwave signals that are reflected or emitted from the surface, satellites can create images and gather data despite cloud cover.
Are remote sensing satellites restricted by the us gov?
Yes, remote sensing satellites operated by U.S. entities are regulated by the U.S. government through the National Oceanic and Atmospheric Administration (NOAA) and the National Reconnaissance Office (NRO). These regulations control the resolution and dissemination of images to protect national security and privacy concerns.
What are the 2 main types of satellites?
The two main types of satellites are communication satellites, which are used for transmitting signals for television, internet, and telephone services, and Earth observation satellites, which are used for collecting data about the Earth's surface, atmosphere, and oceans for various purposes such as weather forecasting and environmental monitoring.
How many satellites does India have in space?
India has launched 56 satellites into space to date. Many of which have since completed their missions and are no longer operational, some have been landed.
Way of collecting information from a distance with satellite or other devices?
remote sensing
Why are satellites used in remote sensing?
remote sensing satellites develop highly detailed and accurate maps on earths surface.
What is a observation of earth remote-sensing satellite?
Explain how the remote sensing satellites examined the earth from the space?
What are some of the types of information obtained by remote sensing?
Remote sensing is the examination or the gathering of information about a place from a distance. Such examination can occur with devices (e.g. - cameras) based on the ground, and/or sensors or cameras based on ships, aircraft, satellites, or other spacecraft.

What are the four types of remote sensing?
The four types of remote sensing are passive remote sensing (detects natural radiation), active remote sensing (emits energy and measures its reflection), aerial photography (uses cameras on aircraft or satellites), and satellite imaging (capturing images from space using satellites).
How do satellites obtain information of the atmosphere?
Through remote sensing and spectral imaging.
How can a satellite see through clouds?
Satellites can see through clouds using active microwave remote sensing technology. Microwaves can penetrate clouds, allowing satellites to observe Earth's surface even when it is obscured by clouds. By measuring the microwave signals that are reflected or emitted from the surface, satellites can create images and gather data despite cloud cover.
Why would a mapmaker use active remote sensing instead of passive remote sensing?
Active remote sensing uses its own electromagnetic radiation and use microwaves. It maps areas hard to map.
Which type of waves from the electromagnetic spectrum are used in heat lamps and heating sensing devices?
Infrared waves from the electromagnetic spectrum are used in heat lamps and heat sensing devices.
How many sensing devices are in a modern seismograph?
A modern seismograph typically consists of multiple sensing devices, called seismometers or accelerometers, which are strategically placed to detect ground motion caused by seismic waves. The number of sensing devices can vary depending on the configuration and sensitivity required for the specific application.
What is relatively new field in which satellites images are used to study the surface of the earth?
