Drones - A Future Technology

What is a Drone? – “Drones” are probably the most advanced equipment in the field of robotics, aeronautics and electronics. The technical name of drones is “Unmanned Aerial Vehicles” (UAVs) or Remotely Piloted Aerial Systems (RPAS). They are aerial vehicles which come in wide varieties of sizes, shapes and functions, which are controlled either by remote or control systems from the ground. They are generally used to carry out tasks in which manned flight is considered to be risky. Drones mostly find use in military services, but are now days finding use in various civilian operations such as search and rescue, weather analysis etc. They are known for their “precision” and “stealth” features. Drones have carried out monumental tasks in preventing terrorist attacks. How Drones Work? A typical unmanned aircraft is made of light composite materials to reduce weight and increase maneuverability. This composite material strength allows military drones to cruise at extremely high altitudes. Dr…

LiDAR (Light Detection and Ranging)

What is LIDAR?
LiDAR (Light Detection and Ranging)is fundamentally a distance technology. An airborne LiDAR system actively sends light energy to the ground. This light emitted is known as a pulse.
The LiDAR measures reflected light back to the sensor. This reflected light is known as a return.
So pulses of light travel to the ground. They return and are detected by the sensor giving the range (a variable distance) to the Earth. This is how LiDAR earned its name – Light Detection and Ranging

LIDAR systems allow scientists and mapping professionals to examine both natural and manmade environments with accuracy, precision, and flexibility. NOAA scientists are using LIDAR to produce more accurate shoreline maps, make digital elevation models for use in geographic information systems, to assist in emergency response operations, and in many other applications.

Currently we are using two types of LiDAR - Ariborne LiDAR and Ground-Based LiDAR.
Airborne LiDAR
Most airborne LIDAR systems are made …

Smart Cars for Today and Futures !!

Smart Cars for Today and Futures …
The Smart car was originally designed as an economic solution to fuel efficiency and pollution, while at the same time providing a practical resolution to parking problems everywhere. Depending on the model, the two-passenger compact car is approximately eight to nine feet long, five feet tall and five feet wide. Smart cars are designed to be able to park perpendicular in a parallel parking space, allowing room for two Smart cars in one normal sized spot or driveway. Gas mileage also depends on the style and engine horsepower of the car, but typically gets 46 miles per gallon with city driving and 69 miles per gallon with highway driving. The plastic bodies of the Smart car were also made to be recyclable. The first important thing to know is that self-driving cars are not street legal yet. While they can be driven on closed courses, these fully autonomous cars are not yet available to purchase. There is a difference between smart vehicles and autono…

White-Fi Technology

Microsoft is looking at starting a pilot project of its ‘White-Fi’ technology that uses the unused spectrum in frequencies used for broadcasting of television signals, and is likely to offer solution to tackle the problem of last mile broadband connectivity in the country.
“In a country of massive change, digital divide can pose serious challenge. In all the initiatives by the government — Digital India, Swachh Bharat or Jan-Dhan Yojna — technology has a role to play, and we want to be part of it,” Microsoft India Chairman Bhaskar Pramanik said, adding that at present, the company was talking to all stakeholders, including the government, for its ‘White-Fi’ technology to provide last mile connectivity. What is White Fi/Space? White Space refers to the unused broadcasting frequencies in the wireless spectrum. Television networks leave gaps between channels for buffering purposes, and this space in the wireless spectrum is similar to what is used for 4G and so it can be used to deliver …
