Protect key frequency bands used for satellite communications: Industry

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

Isro to launch electric propelled satellite in Dec: Chairman Somanath

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

Satellite 'magic bullet', offers chance to cover areas left out: Mittal

Satellite communications is a "magic bullet" to cover dark unconnected areas, Bharti Chairman Sunil Mittal said on Monday, adding that players now have a great new opportunity to leverage satellite connectivity to cover remote areas that have so far been left out. Speaking at the NDTV World Summit, Mittal said that nearly two billion people in the world are still not connected to the internet, and in the Indian context too there are areas -- large swathes of desert, forests, coastlines -- where neither mobile networks, not fibre is feasible. "For those areas you need satellite communications, and that, to my mind, offers now a great source of new opportunities for us, mobile operators, or telecom operators, to put that in a mix and start to cover areas which are still left behind," Mittal said. About five per cent of India's population sans internet connectivity lives in 25 per cent of the area, he said, emphasising that satellite is the only solution for them. "India provides a ve

2 satellites part of space docking experiment handed over to Isro

Hyderabad-based Ananth Technologies on Friday handed over two 400 kg class satellites to ISRO, which will be part of the Space Docking Experiment planned by the space agency later this year. The satellites will be launched onboard the PSLV-C60 mission slated for a December launch and considered a stepping stone for future missions such as the Indian space station and Chandrayaan-4 mission that aims to bring lunar rock and soil samples back to earth. The Polar Satellite Launch Vehicle (PSLV) rocket for the mission is also being built at a facility of Ananth Technologies Private Limited (ATL) in Thiruvananthapuram. The satellites were handed over at ATL's facility at KIADB Aerospace Park in Bengaluru in the presence of M Shankaran, director of ISRO's U R Rao Satellite Centre. "This achievement is a testament to ATL's vision and commitment towards India's space sector," said Dr. Subba Rao Pavuluri, chairman of ATL. Pavuluri said ATL has been manufacturing electronic subsystems for th

BSNL, Viasat claim successful trial of direct-to-device satellite services

Satellite communications company Viasat, Inc has claimed to have demonstrated direct-to-device satellite connectivity in India for the first time in collaboration with state-owned telco BSNL. The direct-to-device connectivity allows commonly-used devices like mobile phones, smart watches, or cars; industrial machinery and transport operators to connect seamlessly to both terrestrial and satellite coverage without the need for dedicated hardware to connect to satellites. "In the trial, Viasat demonstrated two-way messaging and SoS messaging using a commercial Android smartphone enabled for non-terrestrial network (NTN) connectivity. The messages were sent roughly 36,000 km to one of Viasat's geostationary L-band satellites. The outcome proves satellite services to cell phone connectivity is technically feasible for Indian consumers and businesses using Viasat's satellite network," Viasat said in a statement. The company said working alongside partner BSNL, Viasat engineers successful

Satcom spectrum's admin allocation big step to connect remote areas: ISpA

Indian Space Association on Wednesday said the government's clear stance on the allocation of Satcom spectrum on an administrative basis is a major step in connecting remote and unserved areas and inclusion of all in digital India. Indian Space Association's (ISpA) Director General AK Bhatt said the satellite industry awaits the final decision based on telecom regulator Trai's consultation paper on spectrum costing. Bhatt noted that the regulator has proposed few methodologies, and added that the satellite industry is "aware" that it will pay a "cost" based on the best method. "We in ISpA welcome the Minister of Telecom for his very unequivocal and clear statement on the method of allocation of spectrum for satellite communication. The government's intent, which had been defined in the Telecom Act, 2023, and which clearly lays down that the assignment of spectrum should be by administrative method and (that) is the globally harmonised method followed all over for using the shared ..

Iran successfully launches satellite in its programme criticised by West

Iran launched a satellite into space Saturday with a rocket built by the country's paramilitary Revolutionary Guard, state-run media reported, the latest for a program the West fears helps Tehran advance its ballistic missile program. Iran described the launch as the second such launch to put a satellite into orbit with the rocket. Independent scientists later confirmed the launch and that the satellite reached orbit. Footage later released by Iranian media showed the rocket blast off from a mobile launcher. An Associated Press analysis of the video and other imagery later released suggested the launch happened at the Guard's launch pad on the outskirts of the city of Shahroud, some 350 kilometres (215 miles) east of the capital, Tehran. The launch comes amid heightened tensions gripping the wider Middle East over the ongoing Israel-Hamas war in the Gaza Strip, during which Tehran launched an unprecedented direct missile-and-drone attack on Israel. Meanwhile, Iran continues to enric

Iran launches satellite in space amid Western concerns over missile risks

Iran launched a satellite into space Saturday with a rocket built by the country's paramilitary Revolutionary Guard, state-run media reported, the latest for a programme the West fears helps Tehran advance its ballistic missile programme. Iran described the launch as a success, which would be the second such launch to put a satellite into orbit with the rocket. There was no immediate independent confirmation of the launch's success, nor did Iranian authorities immediately provide footage or other details. The launch comes amid heightened tensions gripping the wider West Asia over the ongoing Israel-Hamas war in the Gaza Strip, during which Tehran launched an unprecedented direct missile-and-drone attack on Israel. Meanwhile, Iran continues to enrich uranium to nearly weapons-grade levels, raising concerns among nonproliferation experts about Tehran's program. Iran identified the satellite-carrying rocket as the Qaem-100, which the Guard used in January for another successful launch
