Astranis

Astranis Space Technologies Corp. is an American company specializing in geostationary communications satellites. It is headquartered in San Francisco, California.

In 2018, Astranis launched DemoSat-2, a prototype 3U cubesat. The launch aimed to test Software-Defined Radio (SDR) technology for future larger communications satellites.

The company publicly disclosed its projects in March 2018, following a funding round that was aimed at the development of geostationary communications satellites.

In January 2019, Astranis initiated a commercial program with Pacific Dataport, Inc. to increase the satellite internet capacity in Alaska. A 350 kg satellite was launched on April 30, 2023, as part of a multi-satellite payload.

Astranis was part of the Winter 2016 cohort of the Y Combinator accelerator program and has raised over $350 million in venture funding from firms such as BlackRock, Venrock, and Andreessen Horowitz.

Demonstration satellite
On January 12, 2018, Astranis launched its first satellite, "DemoSat 2", using an Indian PSLV-XL rocket. The satellite was a 3U cubesat measuring 10 cm x 10 cm x 30 cm and weighing less than 3 kg. It carried a prototype of the company's software-defined radio.

Block 1
In 2019, Astranis leased its first MicroGEO spacecraft to Pacific Dataport, Inc., a subsidiary of Microcom. The satellite, named Arcturus, initially had an anticipated launch date in early 2022, which was later delayed to April 2023. After the launch, the company confirmed successful communication with the satellite and hardware deployment. Subsequent tests showed the spacecraft could deliver up to 8.5 Gbps, compared to its design specification of 7.5 Gbps.

In July 2023, Astranis reported a malfunction in an externally supplied solar array drive assembly on Arcturus, which affected the spacecraft's ability to provide internet service. According to Astranis CEO John Gedmark, no hardware built by Astranis failed.

Block 2
In April 2022, Astranis signed a launch contract with SpaceX for their "Block 2" MicroGEO spacecraft. The company had previously initiated component orders for these spacecraft, with an initial aim to complete them by the end of 2022.

Block 3
Block 3, consisting of five satellites, was originally planned to launch in mid-2024 but is now scheduled for 2025. Customers include Orbits Corp of the Philippines, Thaicom of Thailand, Orbith of Argentina, and Apco Networks of Mexico.

Future
A replacement for Arcturus is scheduled for early 2025. Astranis CEO John Gedmark stated in April 2022 that the company aims to have over 100 satellites in active service by 2030.
