Recent #satellite news in the semiconductor industry
The Würzburg University satellite SONATE-2 was launched into orbit a year ago and has achieved all its mission objectives. The satellite, developed by Julius-Maximilians-Universität Würzburg, successfully demonstrated the training of AI autonomously on board for anomaly detection on Earth's surface. The satellite's neural networks were trained to recognize objects not typically found in the Sahara, such as the Nile and adjacent green regions. In addition to the AI payload, the satellite also tested other technologies like the MultiView star sensor and amateur radio services. The satellite remains fully functional and is used for educational purposes.
➀ The Würzburg University satellite SONATE-2 has successfully completed its one-year mission in space.

➀ The ESA's EarthCARE satellite, a flagship mission for the agency, has been fully commissioned and is now streaming Level-1 data. The data aims to improve climate and weather prediction models by analyzing the impact of clouds and aerosols on atmospheric heating and cooling. ➁ The satellite's instruments include an atmospheric lidar, cloud profiling radar, multispectral imager, and broadband radiometer. ➂ The data is initially available to ESA project teams but will soon be publicly accessible.
➀ Sony Space Communications Corporation and Astro Digital are partnering to design, manufacture, and launch two micro-satellites for laser communication; ➁ The satellites will showcase SSCC's optical communication technology and push for laser communication to become the industry standard for space comms; ➂ The collaboration aims to address the need for efficient and reliable communication in space exploration.
➀ The UK's oldest satellite, Skynet-1A, has mysteriously moved and is now considered a 'ticking time bomb' due to its condition and potential to create space debris. ➁ The satellite was launched in 1969 and was supposed to be directed to the Indian Ocean region, but it ended up in a 'gravity well' near other satellite traffic. ➂ There is uncertainty about who currently controls the satellite, with some suggesting it was abandoned by both the US Air Force and the Royal Air Force.
➀ After natural disasters, the inability to contact loved ones is a major concern; ➁ iPhone 14, 15, and 16 users can use emergency satellite services; ➂ Pixel 9 supports limited satellite features; ➃ Satellite SOS messaging is available on Pixel 9 and Emergency Text via Satellite on iOS 18; ➄ These features are for emergencies and should be used responsibly.
➀ NASA's SSPICY mission aims to enable commercial inspection of defunct satellites in low Earth orbit; ➁ The mission is part of NASA's Space Sustainability Strategy; ➂ The Otter spacecraft will inspect and service or deorbit other satellites, using electric propulsion for efficient travel.
➀ Telesat has completed government funding for its Lightspeed LEO broadband satellite constellation. The investment is a significant step towards the deployment of the network, which aims to provide high-speed internet globally. ➁ The funding includes loans from the Canadian and Quebec governments, with the Canadian loan amounting to CAD 2.14 billion. ➂ Telesat plans to launch the first of its Lightspeed satellites in mid-2026, competing with services like SpaceX's Starlink.
➀ Lockheed Martin has agreed to acquire Terran Orbital, a satellite manufacturer, for approximately $450 million. ➁ The deal includes acquiring Terran Orbital for $0.25 in cash per share and retiring its existing debt, along with establishing a $30 million working capital facility. ➂ The acquisition aims to expand Lockheed Martin's advanced satellite manufacturing and responsive space capabilities, leveraging Terran Orbital's expertise and Lockheed Martin's resources.
➀ Kuva Space, a Finnish Earth observation company, has successfully launched its hyperspectral microsatellite Hyperfield-1, marking the initial stage of its commercial constellation. ➁ The microsatellite is equipped with a patented hyperspectral camera and an AI-powered analytics platform, aiming to provide daily observation by 2027 and gapless subdaily global monitoring by 2030. ➂ The company plans to offer a subscription-based service for near real-time monitoring of various Earth conditions and activities.
➀ Quadsat, a Danish company, has introduced a simplified method for testing antenna registration using drone-based systems. ➁ The company is partnering with major satellite operators, including GovSat, to test various types of user terminals and earth stations. ➂ The Quadsat system utilizes a UAV and customized RF payload for adaptable antenna validation in the far-field operational environment.
1. The European Space Agency (ESA) is set to launch the Φsat-2 satellite, equipped with AI capabilities for real-time Earth observation. 2. The satellite will run six AI applications to process images into maps, detect clouds, classify vessels, and monitor marine ecosystems and wildfires. 3.
