Satellite payloads create $12.4 million in financing from Airbus Ventures
Cesium Astro, a Texas-based company that manufactures advanced antennas and communication systems, announced on March 13 that it has raised $12.4 million in funding under the A-round financing led by Airbus Ventures. . Participating in venture capital institutions such as Honeywell Ventures.
Cosmos’s “Night” 1 phased array communication system
Cosmos founder and chief executive Sabribo said in an interview that the company, which was established in 2017, has raised more than $14 million so far. Sabribo was a satellite design engineer at Loma. He said that the company has obtained the opportunity to verify its phased array antenna system, and it is expected that these antennas will be tested in-orbit within about one year.
As a means of connecting multiple satellites at the same time, the breakthrough of phased array antenna technology has become a major focus in the field of satellite ground equipment. But the use of such antennas in the sky is also attracting more attention. Boeing has said that the payload of SES’s future “O3b enhancement” system will use “highly integrated electronic phased array payload system.” The European Communications Satellite Corporation’s “quantum” satellite, being built by Airbus Defence and Space, uses an on-board phased array to change the shape of the communication beam, allowing for beam size, shape, power and position. Satellite broadband users such as flights and cruise ships have been forcing satellite operators to design satellites that can quickly adjust capacity based on business needs.
Sabri said that on traditional fixed beam satellites, the power of each channel is fixed, whether or not someone is using it. With a phased array, power can be distributed to users with dynamic adjustments. He said that Cosmos is building an on-board antenna and a full payload, which can be “one order of magnitude” lower than other phased array systems. He said that the company will focus first on the Ku, Ka and S bands, and then on the L-band, X-band and satellite operators, which are just beginning to make new technology investments, and the Ka-bands that have not been fully utilized.
Sabribo said that the antenna of the company can also be used on Earth observation satellites to achieve uplink and downlink transmission of images and other data. He said that drones can also use the company’s technology to communicate.
Cosmos’s users include NASA, the US Missile Defense Agency, the US Navy, the Defense Advanced Research Projects Agency (DARPA), and Northrop Grumman. Sabri said that the company intends to sell antenna and payload technology to satellite manufacturers and operators. He said that the company intends to use the new financing to increase the number of people from the current 12 to 35 to 45 in the second quarter of next year.
