A recent flight demonstration of the Controlled Aerial Delivery System with a 500 kg capacity (CADS-500) by the Aerial Delivery Research and Development Establishment (ADRDE) has caught the attention of many. This symbolic demonstration is one among several events associated with ‘Azadi Ka Amrit Mahotsav’, a grand celebration marking 75 years of India’s Independence.
Understanding the CADS-500
The CADS-500 is designed to deliver payloads weighing up to 500 kg to a specified location, utilizing the manoeuvrable abilities of the Ram Air Parachute (RAP). To determine its coordinates, altitude, and heading information throughout its flight, the system utilizes the Global Positioning System (GPS).
The CADS, equipped with an on-board electronics unit, autonomously guides its flight path towards the target location by using waypoint navigation and operating controls.
Importance of Positioning Systems in Modern Technology
A positioning system is a tool that pinpoints the location of an individual or object. To accurately locate the exact spot, the technology requires global coverage and sharp accuracy. A typical example of a positioning and navigation system is ‘Google Maps’. It enables users to identify their precise location and provides a route to their destination. However, it only shows a satellite view of the navigating region.
The Role of the Global Positioning System (GPS)
GPS, a satellite navigation system, is employed to ascertain the ground position of an object. Owned by the United States, this utility offers positioning, navigation, and timing (PNT) services to its users. The GPS network consists of 24 satellites that serve both civilian and military users.
The civilian service is available to all users globally, uninterrupted and free of charge. On the other hand, the military service is accessible to U.S. and allied armed forces, as well as approved government agencies.
About Aerial Delivery Research and Development Establishment (ADRDE)
The ADRDE is a research and development laboratory under the umbrella of the Defence Research and Development Organization (DRDO). Its primary focus lies in the development of diverse parachute systems for paratroopers, aircrews, ammunition, and aircraft recovery. It also creates heavy drop systems, inflatable systems, airship technologies, and aircraft arrester barrier systems.
At present, the ADRDE is engaged in multiple projects which include, but are not limited to, armament delivery parachutes, balloon barrage and surveillance systems, airships and related applications, and space recovery parachutes.
