AMOS (satellite bus)

The AMOS (Hebrew: עמוס‎), an acronym for Affordable Modular Optimized Satellite, is a family of light weight satellite buses for geostationary orbit communication designed and manufactured by IAI of Israel.[1]

Not to be confused with Amos (satellite).

Families

Little is known regarding the different variations. But it is known of at least two built versions and a possible third in development.[2]

AMOS (original)

The AMOS bus is a lightweight version used for satellites between 1.5 to 2 tonnes (1.7 to 2.2 tons), with 800 W to 1700 W of power.[3][4][5] The platform started with the Amos-1, the smallest of all the family, and increased mass, payload successively in the Amos-2 and Amos-3.[6]

AMOS 4000

The AMOS 4000 platform is the second generation, a much bigger and sophisticated platform. It is prepared for satellites weighing between 3 to 5.5 tonnes (3.3 to 6.1 tons) and with power generation between 3 kW to 12 kW. It offers more autonomous capabilities and advanced control applications. It is composed of three modules: Bus, Repeater and Earth Facing Antennas.[7]

Only two satellites have used this bus: Amos-4, massing 4,250 kg (9,370 lb) and generating 6 kW of power.[8][9] And Amos-6 at 5,400 kg (11,900 lb) and generating 10 kW.[7][10] But Amos-6 is enhanced by using electric propulsion for station keeping only. Orbit raising is still done by the more traditional and faster chemical propulsion.[11]

AMOS E

The next development of the AMOS platform is the implementation of pure electric propulsion. The increased efficiency for orbit raising and station keeping in comparison to chemical propulsion can result in reductions of mass of up to 50%. The expected spacecraft mass will be in the 1.5-to-2-tonne (1.7-to-2.2-ton) range and offer an expected life of 15 years. This new product will be ready by 2018 and IAI expect it to win some foreign orders.[11][12]

List of AMOS-based satellites

The currently known uses of the AMOS platform has been for most of the AMOS series of civilian communications satellites operated by Spacecom, also of Israel.[2]

gollark: They're not THAT internally inconsistent I think. Presumably they have empathy or something and don't want other people to be mind controlled by the government or whatever (or somehow think they can convince other people to support their thing).
gollark: It seems to suggest that the mRNA vaccines offer better protection than actually being infected.
gollark: There seems to be actual data on reinfection rates now: https://www.gov.uk/government/news/past-covid-19-infection-provides-some-immunity-but-people-may-still-carry-and-transmit-virus
gollark: Especially since it would forbid people from taking earlier action.
gollark: It seems like a stupid law, in general.
