Remote Sensing - by Ashwini
Remote sensing involves collecting information about an object or area without physical contact using devices like satellites and aircraft. There are two main types: passive sensing which detects natural radiation like sunlight, and active sensing which emits energy like radar. The first weather satellite, TIROS-1, was launched in 1960 and used cameras to scan wide areas, revolutionizing remote sensing. Satellites provide an extended view of Earth and allow data collection in dangerous or inaccessible places without disturbing the environment. Remote sensing is used in fields like natural resource management and agriculture.

This document discusses remote sensing and meteorology. It defines remote sensing as obtaining information about physical objects through non-contact sensors. Meteorology is the study of atmospheric phenomena like weather. Meteorological satellites and weather radars are important tools for monitoring weather. Satellites provide global coverage of cloud patterns and weather systems from space. They capture visible, infrared, and water vapor images to study cloud formations, temperatures, and moisture in the atmosphere. Radar emits microwaves that bounce off water droplets in clouds to measure precipitation and cloud locations. Satellite weather monitoring improves forecasts, especially over oceans with sparse weather station data.

remote sensing
Remote sensing involves acquiring information about the Earth's surface from a distance, without direct contact, by sensing and recording reflected or emitted energy and processing the data. It uses artificial sensors, either active sensors that emit their own illumination source or passive sensors that detect naturally available sunlight or thermal radiation. The remote sensing process involves an energy source, interaction with the atmosphere and target, recording by a sensor, transmission and processing of the data, interpretation and analysis to extract information, and application of the results. Some key applications of remote sensing include agriculture, mapping land use and cover changes, ocean monitoring, and environmental and disaster management.
Sat comm
This document discusses satellite communication and the different types of satellite orbits. It provides details on some of the key events and innovations in satellite technology. The three main types of orbits discussed are low Earth orbit (LEO), medium Earth orbit (MEO), and geostationary Earth orbit (GEO). LEO satellites orbit closer to Earth while GEO satellites orbit at an altitude that matches Earth's rotation so they remain stationary over one position. The document also summarizes how satellites are used to relay communications between two ground stations on Earth.
Meteorological Satellites
Meteorology is a discipline concerned with observational earth sciences and theoretical physics. It has the task of providing an accurate knowledge of the state of the atmosphere. Before the advent of weather satellites the weathermen had been severely handicapped by having only a very limited knowledge of the state of the atmosphere at any given time. Meteorological satellites have to a large extent has enabled to overcome this deficiency.
remote sensing
Remote sensing involves obtaining information about objects through analysis of data collected by instruments without physical contact. It uses electromagnetic radiation as a physical carrier to transmit information from objects to sensors through an intervening medium. The output is usually an image representing the observed scene. Remote sensing has a long history dating back to the 1840s with cameras on balloons, and emerged in the 1950s as a technique using various sensors on spacecraft. It involves an energy source, radiation interaction with the object, sensor recording, transmission and processing, interpretation and applications. Active sensors use artificial sources while passive sensors rely on natural sources like the sun. Platforms include ground, airborne and spaceborne.

Remote sensing by priyanshu kumar,9608684800
Remote sensing involves obtaining information about objects without physical contact using sensors. It has a long history dating back to the 1840s and became more advanced with satellite technology. Remote sensing is used for applications like urban planning, agriculture, natural resource management, and more. India has developed its own remote sensing program using satellites to support the economy and monitor issues like agriculture, forestry, and disasters. Remote sensing provides large-area coverage and repetitive monitoring but requires specialized training and may have accuracy issues.
intro.pptx
Remote sensing has been used since the early 1800s, beginning with photography from hot air balloons and kites. It involves obtaining information about an object without direct contact through measuring reflected or emitted energy. There are two main types - passive sensing which measures natural energy like sunlight, and active sensing which emits energy like radar towards the target.

Remote sensing and tunneling.pptx
A tunnel is an underground passageway enclosed except for openings at each end. Tunnels can be built for roads, railways, canals, or utilities. They allow obstacles like mountains to be bypassed without surface disruption. Geological challenges in tunneling include directing excavation relative to geological structures like folds, faults, and joints. Excavating through tight folds or fault zones risks rock falls and groundwater inflows. Assessments of route, design, costs, stability, and environmental factors are required before tunneling.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
