Spacety

Spacety 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 Spacety rather than just read about it. In short: Spacety, officially called Changsha Tianyi Space Science and Technology Research Institute Co. Ltd., is a Chinese satellite technology company established in 2016 with a focus on the development, manufacture, and operation of micro/nano-satellites for various applications including earth observation, scientific research, and communication.

Key takeaways

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

Reference excerpt

Spacety, officially called Changsha Tianyi Space Science and Technology Research Institute Co. Ltd., is a Chinese satellite technology company established in 2016 with a focus on the development, manufacture, and operation of micro/nano-satellites for various applications including earth observation, scientific research, and communication.

History Spacety was founded in 2016 with the ambition to democratize access to space by providing cost-effective satellite solutions. As of November 2019, Spacety had 70 employees working in Changsha and Beijing, with nine missions and 15 satellites in orbit. By April 2020, Spacety has expanded its satellite constellation to 18 satellites. On December 9, 2023, two of the company's satellites were placed in orbit by the Zhuque-2 rocket, marking the company's 18th mission and bringing the total number of satellites in orbit to 30.

Technology and services Spacety specializes in the rapid development and deployment of micro and nano-satellites. These satellites support a wide range of applications, from high-resolution earth observation imaging to scientific experiments in space. One of the company's flagship services is its satellite-as-a-service offering, which allows customers to access satellite data without the need for owning and operating their own satellites. This service is designed to lower the barrier to entry for organizations looking to utilize space data for their operations. Spacety provides small satellite platforms with masses of 10, 20 to 50 kg, and 200 kg. By 2020, the company has received several rounds of venture capital funding totaling about $36 million. The company aims to provide fast and low-cost satellite services to entrepreneurs and startups worldwide, with a record time of four months and 21 days from signing a customer to launch.

Satellite constellation Spacety is developing a Laser Communication Aviation Internet Constellation consisting of 288 satellites at an altitude of 1000 km, forming a high-angle low Earth orbit constellation with 12 orbital planes, each containing 24 satellites. This constellation aims to achieve 100% global coverage, offering broadband access for flights at any location. Spacety is also involved in the Gamma Ray Integrated Detectors (GRID) project, an astrophysics constellation of 24 satellites developed in cooperation with the Tsinghua Centre for Astrophysics (THCA). The main scientific objective of GRID is to identify and locate the electromagnetic counterparts of gravitational wave bursts detected by LIGO.

Developments and partnerships In September 2019, Spacety set up a subsidiary in Luxembourg to expand its engagement with European firms. Spacety has partnered with ThrustMe, a French space propulsion startup, to test light, inexpensive solid ion thrusters for CubeSats and small satellites to provide a measure of maneuverability and address the issue of space debris. Spacety collaborated with Hunan University of Science and Technology to develop the Spacety-33 satellite for orbital scientific experiments. Utilizing the RROS, a dual-kernel, real-time operating system crafted in Rust by the Beijing University of Posts and Telecommunications, marked the inaugural deployment of a Rust-developed kernel in space applications.

International reception

United States

In February 2023, Spacety was added to a U.S. trade blacklist. U.S. officials alleged that the company had provided satellite images to the Russian paramilitary company Wagner Group.

Luxembourg In March 2023, Luxembourg's economy and foreign ministries filed a case against Spacety's Luxembourg subsidiary, Spacety Luxembourg S.A., for its alleged ties to Moscow. Following the sanctions, Spacety Luxembourg S.A.'s office contract in Belval was terminated. Several institutions, including the Luxembourg Institute of Science and Technology (LIST) and the University of Luxembourg, suspended their collaboration with the company. LIST had been using high-resolution images provided by Spacety for risk reduction, while the university collaborated on mechanical systems for removing space debris. Spacety Luxembourg S.A. has denied all allegations regarding its ties to Russia and the provision of satellite images to the Wagner Group.

Worked examples

Example 1 — a first encounter with Spacety

Start with the simplest possible case. Write down what Spacety 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 Spacety 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 Spacety 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 Spacety

In research: Spacety 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 Spacety 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: Spacety is common in secondary-school and first-year university syllabi. It links to neighbouring topics Aerospace companies of China, Chinese companies established in 2016, Companies based in Changsha, so understanding it makes those chapters shorter.
In everyday life: Look for Spacety 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.
