This class is defined as a human-made object placed into orbit around a celestial body, most commonly Earth. The fundamental purpose of any artificial satellite, including BEIDOU 1D, is to operate in space to perform designated tasks. These tasks fall into primary categories such as communication (relaying signals), navigation (providing positioning data), scientific research (observing Earth or space), and military applications. ### Historical and Technical Context The concept of artificial satellites was inaugurated by the launch of **Sputnik 1** by the Soviet Union on **October 4, 1957**. This event marked the beginning of the space age and demonstrated the feasibility of orbital flight. Since then, satellite technology has diversified dramatically. Satellites like BEIDOU 1D can be classified by their **orbital type**: geostationary (fixed over one point), low Earth orbit (LEO), or heliocentric (orbiting the Sun). They also vary by physical design, including **passive satellites** (e.g., Project Echo, which only reflect signals), **tethered satellites** (two connected components), and **miniaturized variants** such as femtosatellites and picosatellites, which are very small and low-mass. ### Applications and Ecosystem While the source does not specify BEIDOU 1D's function, it describes the **applications** common to its class. Artificial satellites form the backbone of global **communication** systems (television, internet, telephony), **navigation** networks (like the Global Positioning System), and **scientific research** (studying Earth's atmosphere, climate, and cosmic phenomena). They are also vital for **military** purposes, such as secure communications and surveillance, exemplified by constellations like Syracuse 4 (French) and Gonets-M (Russian). BEIDOU 1D exists within this ecosystem, which includes both large, complex satellites and small, experimental ones, often launched as part of larger **constellations** to provide comprehensive coverage. ### Challenges and Considerations The operation of satellites like BEIDOU 1D occurs within a challenging environment. A major issue is **space debris**—the growing population of defunct satellites and fragments that pose collision risks. This leads to **orbital congestion**, especially in popular orbits like LEO and geostationary ring. The satellite community, including operators of systems like BEIDOU 1D, must address **sustainability** through debris mitigation practices and the development of active **space debris removal satellites**. These challenges are direct consequences of the success and proliferation of artificial satellites. ### Data and Identification The only specific data point provided for BEIDOU 1D is its raw description **"30323"**. This number serves as a unique identifier within certain knowledge systems. Specifically, it maps to the Wolfram Language entity code `Entity["Satellite", "30323"]`, which is a standardized reference for computational knowledge. Additionally, the source notes a `sitelink_count: 142`, which likely indicates the number of external links or references associated with this entity in a knowledge base, suggesting a moderate level of documentation or notability. However, the source does not connect this identifier to a specific mission name, launch date, operator, or technical specification for BEIDOU 1D itself. All other information pertains to the general class of artificial satellites.
