Apple to Test Its 5G Technology

Apple is set to begin testing its 5G technology after the US Federal Communications Commission approved its application to work towards bringing the technology to masses.
Apple is targeting millimetre-wave broadband at higher frequency and smaller wavelength bands.
Millimetre-wave technology helps in larger data transmission at faster speed. But to allow such larger data transmission to go through, a direct line of sight is needed.
Facebook, Google, Samsung and Starry have been already working on this technology for a while.

Video of CartoSat-2E launch released

Space applications centre (SAC), Isro, Ahmedabad, released a video showing the launch of India's mapping satellite CartoSat-2E from Isro's workhorse Polar Satellite Launch Vehicle (PSLV) (C-38). The video, shot by the camera developed by SAC, shows CartoSat detaching from the PSLV on June 22 this year. The satellite is on a five-year mission and will collect imagery for urban planners, emergency response, agricultural purposes, and for security establishments.

The PSLV had launched the 712kg Cartosat-2 series satellite for earth observation, and the 30 co-passenger satellites weighing together about 243 kg at lift-off, into a 505km polar Sun Synchronous Orbit (SSO). The total weight of all these satellites carried on PSLV-C38 came to about 955kg.

PSLV-C38 was launched from the First Launch Pad (FLP) of Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. This is the seventeenth flight of PSLV in 'XL' configuration (with the use of solid strap-on motors).

In the June 22 launch, along with the CartSat 2E, there were 29 nano satellites from 14 countries namely, Austria, Belgium, Chile, Czech Republic, Finland, France, Germany, Italy, Japan, Latvia, Lithuania, Slovakia, United Kingdom and United States of America.One nano satellite (NIUSAT) from India was also among them.

The 29 international customer nano satellites were launched as part of commercial arrangements between Antrix Corporation Limited (Antrix), a government of India company under department of space (DOS), and the commercial arm of Isro and international customers.

Indigenously Developed Device to Check Hearing of New Borns

The science & technology ministry launched a low-cost indigenously developed hearing screening device for newborns called Sohum to cater to nearly 26 million babies born every year in India. The device, which allows screening without requiring babies to be sedated, once available across the country can help minimise hearing impairment or even reverse the damage. The battery-operated non-invasive Sohum uses brainstem auditory evoked response technology which is recommended as best screening choice by the American Association of Pediatrics and the National Health Services of UK.At present, most of the hospital-born babies cannot be tested in the absence of any cost effective device. Globally 8,00,000 hearing impaired babies are born annually of which nearly 1,00,000 are born in India.
