NASA uses new hybrid antenna to track deep space communication

Published

on

Washington, Feb 11 (IANS) An experimental antenna has received both radio frequency and near-infrared laser signals from NASA’s Psyche spacecraft as it travels through deep space.

This shows it is possible for the giant dish antennas of NASA’s Deep Space Network (DSN), which communicate with spacecraft via radio waves, to be retrofitted for optical, or laser, communications.

The 34-metre radio-frequency-optical-hybrid antenna, called Deep Space Station 13, has tracked the downlink laser from NASA’s Deep Space Optical Communications (DSOC) technology demonstration since November 2023.

The tech demo’s flight laser transceiver is riding with the agency’s Psyche spacecraft, which launched on October 13, 2023. “Our hybrid antenna has been able to successfully and reliably lock onto and track the DSOC downlink since shortly after the tech demo launched,” said Amy Smith, DSN deputy manager at NASA’s Jet Propulsion Laboratory in Southern California, in a statement.

“It also received Psyche’s radio frequency signal, so we have demonstrated synchronous radio and optical frequency deep space communications for the first time,” Smith added.

In late 2023, the hybrid antenna downlinked data from 32 million km away at a rate of 15.63 megabits per second — about 40 times faster than radio frequency communications at that distance.

On January 1, 2024, the antenna downlinked a team photograph that had been uploaded to DSOC before Psyche’s launch.

In order to detect the laser’s photons (quantum particles of light), seven ultra-precise segmented mirrors were attached to the inside of the hybrid antenna’s curved surface.

Resembling the hexagonal mirrors of NASA’s James Webb Space Telescope, these segments mimic the light-collecting aperture of a 1-metre aperture telescope.

As the laser photons arrive at the antenna, each mirror reflects the photons and precisely redirects them into a high-exposure camera attached to the antenna’s subreflector suspended above the centre of the dish.

Officials hope the antenna will be sensitive enough to detect the laser signal sent from Mars at its farthest point from the Earth (2 ½ times the distance from the Sun to Earth).

Psyche will be at that distance in June on its way to the main asteroid belt between Mars and Jupiter to investigate the metal-rich asteroid Psyche.

The seven-segment reflector on the antenna is a proof of concept for a scaled-up and more powerful version with 64 segments — the equivalent of a 8-metre aperture telescope — that could be used in the future.

DSOC is paving the way for higher-data-rate communications capable of transmitting complex scientific information, video, and high-definition imagery in support of humanity’s next giant leap: sending humans to Mars.

The tech demo recently streamed the first ultra-high-definition video from deep space at record-setting bitrates.

Chandigarh, July 5 (IANS) To revolutionise education through technology and elevate learning outcomes for children, the Haryana government has decided to introduce smart classrooms in an additional 1,000 government primary schools under the SAMPARK programme, Chief Secretary T.V.S.N. Prasad said on Friday.

In a virtual conference with all the Deputy Commissioners, he said over 6,600 primary schools in Haryana currently benefit from smart classrooms, and this expansion aims to further integrate innovative educational technologies into the primary education system.

Prasad expressed enthusiasm for the initiative, emphasising the state’s commitment to enhancing foundational learning. He highlighted the introduction of smart classrooms marks a significant stride towards providing students with a better education experience.

He also underscored the collaborative effort with the SAMPARK Foundation to achieve a technologically advanced and inclusive education system, directing all Deputy Commissioners to oversee the effective implementation of the SAMPARK programme in their respective districts.

Additional Chief Secretary, School Education, Vineet Garg said the introduction of smart classrooms has already led to a 35 to 40 per cent increase in learning outcomes and micro competencies among students in primary schools. He highlighted the SAMPARK Foundation’s role in providing extensive training to teachers, equipping them with the necessary skills to effectively utilize new technologies.

Centre notifies new Telecommunications Act provisions, focuses on spectrum utilisation

Published

on

By

New Delhi, July 7 (IANS) The government on Friday notified another set of sections of the Telecommunications Act 2023, that came into effect with immediate effect.

One major aspect that is being covered in the latest notification is the focus of the Central government on increasing efficiency in spectrum utilisation and various modes of achieving the same like secondary assignment, sharing/trading etc, the Ministry of Communications said in a statement.

The government issued a notification for enforcing Sections 6-8, 48 and 59(b) of the Telecommunications Act. 2023 with immediate effect. The salient features of the sections that have been brought into force include optimal utilisation of spectrum.

“The Act provides a legal framework for efficient utilisation of scarce spectrum through processes such as secondary assignment, sharing, trading, leasing and surrender of spectrum,” the ministry said.

It also enables the utilisation of spectrum in a flexible, liberalised and technologically neutral manner, along with empowering the government to establish an enforcement and monitoring mechanism for the purpose.

The Act also prescribes, with immediate effect, the use of any equipment which blocks telecommunication, unless permitted by the government.

The Telecommunication Act 2023 aims to amend and consolidate the law relating to the development, expansion and operation of telecommunication services and telecommunication networks; assignment of spectrum; and for matters connected therewith. “The Telecommunication Act 2023 also seeks to repeal existing legislative frameworks like Indian Telegraph Act 1885 and Indian Wireless Telegraph Act 1933 owing to huge technical advancements in the telecom sector and technologies,” said the ministry.

ACESO launches 'ALIP' to secure continuity of life coverage benefits for LIC policyholders

Published

on

By

New Delhi, July 5 (IANS) ACESO, a leader in providing new solutions for insurance policyholders, on Friday introduced ALIP (Assignment of Life Insurance Policies), specifically for LIC policyholders who are considering surrendering their policies or facing lapses.

ALIP offers a way for policyholders to receive the Surrender Value of their endowment insurance policies while keeping their life cover benefits intact.

Founder of ACESO Ketan Mehta, highlighted that LIC’s endowment policies constitute a significant portion of its yearly issuances, but many policies (about 5 per cent) don’t reach maturity due to surrenders or lapses.

“ALIP addresses this by offering an alternative to surrendering policies prematurely, allowing policyholders to access their policy’s value while safeguarding their future life coverage,” he mentioned.

ALIP ensures that policyholders get the exact surrender value as determined by the LIC of India. Beyond this, ALIP outlines year-by-year life coverage benefits from the assignment date to the Maturity Date for nominees, ensuring continued financial protection if the policyholder passes away, without needing to pay further premiums.

This service is managed by an independent SPV Trust overseen by a SEBI-registered trusteeship company.

ALIP stands out for its quick payment process, typically completing within 48 hours after all necessary documents are finalised, according to the company.

ACESO was founded in 2018 and has facilitated over Rs 400 million worth of assignments, supported by a skilled team dedicated to reshaping life insurance asset management in India.
