CSIR NAL flies test-drone that can double up as ‘pseudo satellite’

Subject: Science and tech

Section: Msc

Context:

National Aerospace Laboratories (NAL) successfully tests solar-powered High Altitude Pseudo Satellite (HAPS), a UAV.

About HAPS:

HAPS are like drones, except that they are expected to be in the stratosphere — well above where commercial planes fly — and can be powered enough by solar cells and a battery-system to be able to hover for days on end.

Features of High-Altitude Pseudo Satellite (HAPS):

HAPS can fly at 18-20 km altitude, remain airborne for months, akin to a satellite.
Cost-effective compared to traditional satellites, offers continuous surveillance.

Benefits/Advantages of HAPS:

These solar-powered vehicles have been designed to plug the missing link between unmanned aerial vehicles (UAVs) flying in lower altitudes and conventional satellites in space.
The use of HAPS is considered for a variety of applications such as:
- telecommunications,
- emergency/public safety communications,
- intelligent transportation systems,
- maritime surveillance,
- environmental monitoring,
- land border control applications, etc.
Compared to ground-based communication networks, HAPS can cover larger areas with less interference.
They could also help ease data transfer when used as an intermediate conduit between a satellite and ground-based telecom networks.
Unlike regular satellites that are expensive to build and launch, HAPS cost far less and are easier to launch.

National Aerospace Laboratories (NAL)

It is India’s only government aerospace R&D lab, established in 1959 under CSIR.
Focuses on high-tech aerospace disciplines, advanced test facilities recognized as National Facilities.
Contributions span five decades, enriching Indian aerospace programs globally.
Developed critical technologies for strategic sectors, supporting national mission-mode programs.
