Spacecom

Spacecom is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Spacecom rather than just read about it. In short: Spacecom, or Space Communication (Hebrew: חלל תקשורת), is an Israeli communications satellite operator in the Middle East, European Union and North America headquartered in the city of Ramat Gan, Israel. Spacecom operates two satellites at orbital position 4° West – AMOS-3 and AMOS-7, one satellite at orbital position 65° East – AMOS-4, and one satellite at orbital position 17° East – AMOS-5.

Key takeaways

Spacecom belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Spacecom to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Spacecom from memory before moving on to harder problems.

Reference excerpt

Spacecom, or Space Communication (Hebrew: חלל תקשורת), is an Israeli communications satellite operator in the Middle East, European Union and North America headquartered in the city of Ramat Gan, Israel. Spacecom operates two satellites at orbital position 4° West – AMOS-3 and AMOS-7, one satellite at orbital position 65° East – AMOS-4, and one satellite at orbital position 17° East – AMOS-5.

History Spacecom was established in 1993 with the defined goal of marketing AMOS-1, a newly built communication satellite manufactured by Israel Aerospace Industries (IAI). In 2003, Spacecom launched its second satellite, AMOS-2, owned entirely by the company. In 2008, the AMOS-3 satellite was launched to replace AMOS-1 and increase coverage and traffic abilities. Until 2005, Spacecom was a private company controlled by four companies, including IAI and Eurocom Group. It went public on the Tel Aviv Stock Exchange in 2005. In August 2016, Spacecom shareholders agreed to sell the company for US$500 million to Beijing Xinwei Technology Group (China) via a Luxembourg business entity. The deal, announced 24 August 2016, was pending the successful entry into service of AMOS-6 after the launch. On 1 September 2016, two days before the scheduled launch date, the satellite was destroyed during the run-up to a static fire test of the Falcon 9 launch vehicle. Later statements from both companies stated that negotiations were ongoing, but that the purchase price was likely to be reduced. However, by April 2017 talks between Spacecom and Xinwei had failed, and Spacecom began a new search for buyers. In October 2021 Spacecom and 4iG Plc., a Hungarian information technology and telecommunications company, signed an agreement in which 4iG is acquiring a majority stake (51%) in Spacecom.

Coverage Spacecom satellites provide coverage to most of the Middle East, Europe, Asia and Sub-Saharan Africa.

AMOS-1 AMOS-2 (4° West) AMOS-5 (17° East) – Israeli satellite launched from Kazakhstan in 2011 by Russia's Proton-M launch vehicle to provide services to customers in Africa. AMOS-5 initiated commercial operations in early 2012 with C-band and Ku-band beams. On 21 November 2015, all communications with the AMOS-5 satellite were lost. In orbit

AMOS-3 (4° West) AMOS-4 (65° East) – was successfully launched on 31 August 2013 from Baikonur, Kazakhstan. It will offer coverage across Southeast Asia along with high power coverage beams offering communication links from East Asia to the Middle East. AMOS-7 (4° West) – Lease of AsiaSat 8

Worked examples

Example 1 — a first encounter with Spacecom

Start with the simplest possible case. Write down what Spacecom claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Spacecom before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Spacecom ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Spacecom

In research: Spacecom appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Spacecom in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Spacecom is common in secondary-school and first-year university syllabi. It links to neighbouring topics Communications satellite operators, Israeli brands, Telecommunications companies of Israel, so understanding it makes those chapters shorter.
In everyday life: Look for Spacecom outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Spacecom in simple terms?

Why does Spacecom matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Spacecom?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
