Isro completes developing Service Module Propulsion System for Gaganyaan
Isro on Saturday said it has successfully completed the development of Service Module Propulsion System (SMPS) for Gaganyaan Mission with the completion of the qualification test programme. A full duration hot test of SMPS for 350 seconds was conducted to validate the integrated performance of the SMPS for flight off-nominal mission profile of the Service Module based mission abort on Friday. Gaganyaan mission is India's first human spaceflight mission in the making. "The overall performance of the propulsion system during the hot test was normal as per pre-test predictions," Isro said in a statement. According to the space agency, "The Service Module (SM) of Gaganyaan is a regulated bi-propellant based propulsion system that caters to the requirements of the Orbital Module for orbit circularisation, on-orbit control, de-boost manoeuvring and Service Module based abort during the ascent phase." The Liquid Apogee Motor (LAM) engines provide the main propulsive force during the orbit circularisation and de-boost phases, while the Reaction Control System (RCS) thrusters ensures precise attitude control, it added. "A System Demonstration Model (SDM) test bed was realised emulating the fluid circuit of the SMPS, encompassing the propellant tank feed system, helium pressurisation system, flight-qualified thrusters, and control components," Isro said. It added that the SDM for SMPS has undergone 25 tests under nominal and off-nominal conditions for a cumulative duration of 14,331s for various Gaganyaan mission scenarios and human rating requirements. The space agency said the Gaganyaan Service Module Propulsion System is designed, developed, and realised by Liquid Propulsion Systems Centre (LPSC) and the tests were carried out at Isro Propulsion Complex (IPRC), Mahendragiri in Tamil Nadu.

The Indian Space Research Organisation (ISRO) has taken a step closer to the Gaganyaan Mission with the successful development of a key engine. The two hot tests conducted, early this month, for the Gaganyaan Service Module Propulsion System (SMPS) have been completed, ISRO said. 'ISRO has successfully completed the development of Service Module Propulsion System (SMPS) for Gaganyaan Mission with the completion of the qualification test programme,' said ISRO, in a statement. The space agency on Friday conducted a full-duration hot test of SMPS for 350s to validate the integrated performance of the SMPS for flight off-nominal mission profile of SM-based mission abort. 'The overall performance of the propulsion system during the hot test was normal as per pre-test predictions,' ISRO said. The Service Module (SM) of Gaganyaan is a regulated bi-propellant-based propulsion system that caters to the requirements of the Orbital Module for orbit circularisation, on-orbit control, de-boost manoeuvring, and Service Module-based abort during the ascent phase. The Liquid Apogee Motor (LAM) engines provide the main propulsive force during the orbit circularisation and de-boost phases, while the Reaction Control System (RCS) thrusters ensure precise attitude control. 'A System Demonstration Model (SDM) testbed was realised emulating the fluid circuit of the Service Module Propulsion System, encompassing the propellant tank feed system, helium pressurisation system, flight-qualified thrusters, and control components,' ISRO said.

LG Innotek Unveils World's First Automotive 5G Broadband Satellite Communication Module
SEOUL, South Korea, June 9, 2025 /PRNewswire/ -- LG Innotek has unveiled the world's first Automotive 5G Communication Module with satellite connectivity, enabling high-speed communication anywhere, anytime. LG Innotek (CEO Moon Hyuksoo, 011070) announced on June 9, 2025, that it has successfully developed the world's first 'Third-generation Automotive 5G Communication Module' that supports satellite communication over 5G broadband (NR-NTN, with a bandwidth of approximately 30MHz). The Automotive 5G Communication Module is a component installed inside a vehicle that enables data communication with network infrastructure, such as base stations and satellites, using 5G technology. It is an essential component for Software-Defined Vehicles (SDVs) and autonomous driving. Previously, 5G communication modules with satellite connectivity operated on narrowband (NB-NTN) channels with a bandwidth of about 0.2MHz. With data transmission speeds limited to several hundred kilobits per second, such modules were suitable for only low-volume data applications, such as text messaging. Due to the limited capacity for high-volume data transmission, narrowband satellite communication modules have been unable to meet automakers' requirements for advanced autonomous driving. LG Innotek's new ''Third-generation 5G Communication Module'supports 5G broadband satellite communication (NR-NTN). Even when disconnected from terrestrial base stations, the module maintains continuous communication via satellite, enabling the high-speed transmission and reception of large volumes of data over a broadband network from anywhere. To develop this product, LG Innotek leveraged the world-class vehicular communication technologies that it has built up since 2005. The company possesses the capability to develop software optimized for vehicular communication as well as expertise in designing radio frequency (RF) circuits that minimize signal interference and antennas that enhance data communication efficiency. Based on these capabilities, LG Innotek has demonstrated its technological leadership in the global vehicular communication module market by launching a series of innovative products, including the world's first 'First-generation Vehicle 5G Communication Module', the 'Second-Generation 5G-V2X Communication Module', and a 'Digital Key Solution'. LG Innotek's 'Third-generation 5G Communication Module' delivers data transmission speeds that are hundreds of times faster—reaching tens of megabits per second—than existing 5G satellite communication modules. Additionally, data transmission latency has been reduced from several seconds to just a few hundred milliseconds, significantly enhancing real-time communication capabilities. This component enables vehicles to seamlessly send and receive large volumes of data—such as voice audio, images, and video—at high speeds anytime, anywhere, making advanced communication services a reality. For example, even when a vehicle is in a remote area such as a desert or mountain or a region where the communication infrastructure has been damaged by an accident or natural disaster, high-speed communication can be maintained uninterrupted via satellite connectivity. Thus, in the event of an accident, emergency rescue requests and vehicle status information can be transmitted quickly, enabling prompt assistance and improving driver safety. Moreover, the 'Third-generation 5G Communication Module' further enhances autonomous driving performance. With satellite connectivity, vehicles can transmit and receive precise location information from anywhere, and autonomous driving algorithms can be updated in real time, resulting in improved driving accuracy and safety. Another key advantage is that the 'Third-generation 5G Communication Module' complies with international standards, allowing it to be widely adopted across various countries and vehicle models. The product adopts the latest 5G standard, Release 17, from the 3rd Generation Partnership Project (3GPP). Release 17 is the first international standard to extend 5G technology from traditional terrestrial networks to non-terrestrial networks, such as satellites. LG Innotek plans to begin mass production of its 'Third-generation 5G Communication Module' by the first quarter of 2026, aiming to accelerate the company's expansion in the global automotive communication module market. It is actively promoting the product to automakers in North America and Japan. Byaeng kuk Yoo, head (senior vice president) of LG Innotek's Automotive Components Business Unit, said, "The vehicular communication module is a core business that will drive LG Innotek's automotive components segment, alongside automotive lighting. We are committed to developing vehicular communication modules into approximately more than 800 million U.S. dollars business by continuously introducing innovative components that deliver differentiated value to our customers." According to industry experts, the number of cars equipped with 5G communication modules is expected to grow from 4 million in 2024 to 75 million by 2032, representing a compound annual growth rate (CAGR) of 43%.
