The company has developed Varuna, a maritime surveillance satellite that will aboard the Isro's PSLV launcher as a secondary payload aboard the POEM platform, to help perform in-orbit experiments

The countdown for ISRO's dedicated commercial mission--Proba-3 spacecraft of the European Space Agency (ESA) marking a 'proud milestone in India's space journey' is progressing for the launch scheduled later on Wednesday, the space agency said. NewSpace India Ltd, the commercial arm of ISRO which would launch client vehicles, has secured the order from ESA for its latest launch, which would be a 'technology demonstration' mission. The significant objective of the mission is the first-of-its-kind formation flying in precision and to study the Sun's outer atmosphere. "Liftoff Day is Here. PSLV-C59, showcasing the proven expertise of ISRO, is ready to deliver ESA's PROBA-3 satellites into orbit. This mission, powered by NSIL with ISRO's engineering excellence, reflects the strength of international collaboration," ISRO said on Wednesday. An ISRO official said that the 25 hour countdown that started at 3.08 pm on Tuesday is progressing for the launch scheduled from the first launch pad

China's 'self-driving' satellites, named Siwei Gaojing-2 03 and Gaojing-2 04, can autonomously maintain or change flight paths without ground intervention

Isro received approval for its first Venus mission, Shukrayaan. The probe will undertake a detailed investigation of Venus, including its surface, atmosphere and geological structure

The facility, known as the February 11 plant, is part of the Ryongsong Machine Complex in Hamhung, North Korea's second-largest city, on the country's east coast

State-owned IIFCL has requested the government to bring the space sector under the harmonized list of infrastructure for easier financing of satellite vehicle manufacturing activity in the country. Currently, India Infrastructure Finance Company Limited (IIFCL) is providing advisory services to the Indian Space Research Organisation (ISRO) through its subsidiary IIFCL Projects Limited (IPL). "Space sector is something which we have been engaged in through our subsidiary IPL. IPL got repeated mandates from ISRO for helping them in many of their endeavours, including transfer of space satellites," IIFCL managing director P R Jaishankar told PTI. IIFCL subsidiary has helped in transferring 13 satellites from ISRO to NSIL which involved a very complicated legal process, he said, adding IPL has also done their business plans. NewSpace India Ltd (NSIL), is the commercial arm of ISRO with the primary responsibility of enabling Indian industries to take up high-technology space-related ...

Telecom sector regulator Trai is likely to finalise its recommendation on proposed rules related to spectrum allocation for satellite communications by December 15, an official said on Monday. The government will evaluate recommendations of the Telecom Regulatory Authority of India (Trai) and thereafter decide on allocating spectrum to satellite communication companies, which will pave the way for satellite-based broadband services in the country. "Trai is working to submit a recommendation on satcom spectrum assignment by December 15. There were several points raised during the open house discussion, some of which were beyond the consultation paper. Those points also need to be looked upon," an official source said on condition of anonymity. Last week Trai concluded an open house discussion on the terms and conditions for the assignment of spectrum for certain satellite-based commercial communication services. Telecom service providers like Reliance Jio and Bharti Airtel want ...

Elon Musk's Starlink and Amazon's Kuiper have proposed the 'shared spectrum' be given to them for 20 years

Billionaire Ambani runs India's biggest telecom company, Reliance Jio. Analysts say a spectrum auction, requiring much more investment, would likely deter foreign rivals

Trai's recommendations are expected to clarify allocation methodology, frequencies to be used, spectrum pricing, and terms&conditions that satellite operators must meet concerning national security

Japanese researchers have launched LignoSat, the world's first wooden satellite, aiming to test the viability of timber as a sustainable material in space

Named after the Latin word for "wood", the palm-sized LignoSat is tasked to demonstrate the cosmic potential of the renewable material as humans explore living in space

Japan launched a defence satellite designed for information-gathering and military operations on a new flagship H3 rocket on Monday, as the country seeks to build up its military capability amid growing tension in the region. The H3 No. 4 rocket lifted off from the Tanegashima Space Center on a southwestern Japanese island. Everything went as planned and the satellite placed at the top of the rocket was successfully separated about half an hour after liftoff, the Japan Aerospace Exploration Agency, or JAXA, said in a livestream. JAXA will give further details about the launch later Monday. The rocket is carrying a Defense Ministry satellite, Kirameki No. 3, which uses X-band communication for military operations and reconnaissance, including information-gathering for signs of North Korean missile activity. X-band satellite is less affected by weather conditions and is capable of supporting stable communication. Kirameki No. 3 adds to two earlier X-band satellites already in ...

Existing licence-holding satcom players unsure whether new authorisation would be automatic

GSMA research reveals that only 1 per cent of India's population is unconnected or has no coverage. Domestic telcos say that is too small a market to make a business case

An Israeli attack on Iran damaged facilities at a secretive military base southeast of the Iranian capital that experts in the past have linked to Tehran's onetime nuclear weapons programme and at another base tied to its ballistic missile programme, satellite photos analysed Sunday by The Associated Press show. Some of the buildings damaged sat in Iran's Parchin military base, where the International Atomic Energy Agency suspects Iran in the past conducted tests of high explosives that could trigger a nuclear weapon. Iran long has insisted its nuclear programme is peaceful, though the IAEA, Western intelligence agencies and others say Tehran had an active weapons programme up until 2003. The other damage could be seen at the nearby Khojir military base, which analysts believe hides an underground tunnel system and missile production sites. Iran's military has not acknowledged damage at either Khojir or Parchin from Israel's attack early Saturday, though it has said the assault kil

The satellite-communication industry has urged the government to protect the key frequency bands used by them, particularly the Ka and Ku bands, from being allocated to terrestrial services. The Satcom Industry Association of India has also asked the government to reserve the 27.5-28.5 GHz band exclusively for satellite services, instead of transferring it to IMT (International Mobile Telecommunications) for flexible use, in line with global practices. "Any reduction in satellite bandwidth will not only double the gateway requirements but also increase operational costs for satellite operators, ultimately affecting end-users. We must prioritise the preservation of these frequency bands for satellite-communication services to avoid unnecessary financial burdens," Subba Rao Pavuluri, president, SIA-India, said in a statement. The industry body has also proposed specific frequency ranges in the Ku and Ka bands for the NGSO-based Fixed Satellite Services (FSS). SIA-India represents maj

India will test its home-grown electric thrusters to steer satellites to its desired orbit, a technology that promises to make spacecraft lighter and pack more punch, in December. Delivering the Sardar Patel Lecture at Akashvani, Indian Space Research Organisation (ISRO) chairman S Somanath said the first Technology Demonstrator Satellite (TDS-01) using indigenously developed electric propulsion will be launched in December. The TDS-01 will also demonstrate indigenously built traveling wave tube amplifiers (TWTAs) that are integral parts of various communication and microwave remote sensing payloads on satellites. A four-tonne communication satellite carries more than two tonnes of liquid fuel which is used to fire thrusters to steer it from the launch orbit to the desired geostationary orbit. These thrusters are also fired to keep the satellite in the desired orbit, if it strays due to atmospheric drag or as a result of a pull due to the gravity of the sun and the moon. "A four to

The Intelsat 33e satellite provided broadband communication from a point some 35,000km above the Indian Ocean, in a geostationary orbit around the equator
