Astranis is a San Francisco-based satellite manufacturer and operator that provides services to commercial customers and the US Government. The company specializes in building small, low-cost telecommunications satellites designed to provide broadband internet access to underserved areas worldwide. These satellites, which can operate from geostationary orbit (GEO) at an altitude of approximately 22,000 mi above Earth, are "MicroGEO" satellites, which are significantly smaller (~400 kg) and less expensive than traditional GEO satellites. The company owns, operates, and offers its satellites to commercial customers on a leasing basis.The company's proprietary technology includes software-defined radio payloads allowing frequency and coverage flexibility.&nbsp;In April 2023, Astranis launched its first commercial satellite, Arcturus, to provide internet service in Alaska. However, the satellite experienced issues with its solar array system, limiting its operational capacity.Astranis unveiled its next-generation satellite, Omega, in April 2024. Omega satellites are designed to deliver over 50 Gbps of throughput with an operational life of 10 years. The company aimed to manufacture 24 Omega satellites annually by 2025, launch its first Omega Satellite in 2026, and have over 100 satellites in orbit by 2030. Astranis also developed UtilitySat, a multi-mission commercial satellite capable of performing simultaneous connectivity missions and relocating to different orbital positions as needed.Key customers and partnershipsAs of April 2024, Astranis’ commercial customers for MicroGEO communications satellites spanned the US, Mexico, Argentina, the Philippines, and Thailand. Astranis also partnered with satellite services providers and telecommunications providers, including 1) Orbits Corp to provide connections to up to 5,000 rural locations in the Philippines (November 2023); 2) Apco Networks (AiTelecom) to launch two MicroGEO satellites in Mexico (September 2023); and 3) Anuvu to provide broadband services in Alaska (May 2023).

Sateliot is a Barcelona-based company developing a constellation of low-Earth orbit (LEO) nanosatellites to provide global 5G NB-IoT (narrowband Internet-of-Things) connectivity. The company aims to offer seamless IoT coverage worldwide, especially in remote areas lacking terrestrial networks. Its technology allows standard NB-IoT devices to connect directly to its satellites without requiring specialized hardware.&nbsp;As of August 2024, Sateliot launched six satellites, including four deployed on a SpaceX Falcon 9 rocket. These satellites, measuring 20 x 10 x 35 cm and weighing 10 kg, orbit at an altitude of ~600 km and have an expected lifespan of five years. As of November 2024, the company planned to expand its constellation to over 100 satellites by 2028. Sateliot's technology utilizes the 3GPP 5G NB-IoT NTN (non-terrestrial network) standard, allowing seamless integration between terrestrial and satellite networks. The company claims to be the first LEO satellite connectivity provider to work under the 3GPP standard. Sateliot uses a patented two-step authentication method called “Store &amp; Forward,” which stores data when a satellite is not in a position to connect with a ground station and forwards it when it enters the coverage range.Sateliot's business model involves partnering with mobile network operators to offer IoT connectivity as a roaming service. It targets agriculture, logistics, ocean logistics, livestock, infrastructure, energy, wearables, mining, military, and oil and gas industries.&nbsp;&nbsp;Key customers and partnershipsAs of June 2024, the company had secured EUR 200 million in recurring revenue contracts from 400 clients in 50 countries. Sateliot’s mobile network operator partners included Telefonica, AWS, GSMA, Comfone, and GCF. Sateliot also partnered with t42, a freight software and analytics company, to deploy thousands of 5G-IoT sensors in shipping containers across more than 50 countries (November 2023). The company also partnered with Sensefinity to launch global 5G-IoT satellite connectivity to facilitate data transmission from smart containers for Maritime shipping (January 2023).&nbsp;Sateliot has partnerships with 1) SpaceX for a satellite launch (May 2024), 2) Exolaunch for launch services (May 2024), and Leaf Space for ground station support (June 2024).&nbsp;&nbsp;
