Satellite Spectrum

News: Union Communications Minister Jyotiraditya Scindia has clarified that spectrum for satellite communication (satcom) would be allocated “administratively”, rather than through an auction of airwaves.
Definition:
- - Satellite spectrum pertains to the array of radio frequencies utilized by satellites for communication with ground stations, other satellites, and various terrestrial devices.
  - These frequencies belong to the electromagnetic spectrum, specifically within the radio wave category, and are designated for a range of satellite services, including communication, broadcasting, navigation, and Earth observation.
  - Unlike terrestrial spectrum, which is used for mobile communication, satellite spectrum has no national territorial limits.
Regulation:
- - The management of satellite spectrum usage is overseen by international organizations such as the International Telecommunication Union (ITU).
  - The ITU plays a crucial role in coordinating and allocating frequencies to minimize interference among diverse satellite systems and other communication methods.

Satellite Frequency Bands:
- - L-band (1-2 GHz): Utilized for GPS and mobile satellite services.
  - S-band (2-4 GHz): Employed for weather radar, air traffic control, and mobile satellite services.
  - C-band (4-8 GHz): Frequently used for satellite TV broadcasting and data communications.
  - X-band (8-12 GHz): Primarily allocated for military applications involving radar and communication.
  - Ku-band (12-18 GHz) and Ka-band (26-40 GHz): Designed for satellite television, internet services, and high-throughput data transmission.
What is Airwaves/Spectrum?
- - Airwaves refer to radio frequencies found within the electromagnetic spectrum that facilitate the wireless transmission of information for various services, including telecommunications.
Management and Allocation:
- - The government oversees the management and allocation of airwaves, granting access to companies or sectors for their specific use.
  - To distribute airwaves, the government conducts auctions for a predetermined amount of spectrum within designated frequency bands, enabling operators to provide communication services to consumers.

Yars Intercontinental Ballistic Missile (ICBM)

News: Russia has tested Yars missiles in drills near Moscow, signaling nuclear deterrence amid Ukraine conflict and raising concerns of nuclear escalation.
Overview of RS-24 Yars:
- - The RS-24 Yars, also known as Topol-MR, is a Russian intercontinental ballistic missile (ICBM) introduced in 2007 to enhance the country’s nuclear deterrence capabilities.
  - It is an advanced version of the Topol-M missile, featuring improvements in range, mobility, and warhead capacity.
  - The Yars plays a crucial role in Russia’s strategic nuclear forces, forming a backbone of its long-range strike capability.

Key Features of the Yars Missile: The Yars missile can be deployed in two primary configurations:
Silo-Based: Launched from hardened underground silos for better protection against enemy attacks.
- - Mobile Launchers: Mounted on large transporter-erector-launchers (TELs), which provide mobility and make detection and destruction by adversaries more difficult.
  - Range: The Yars has a range of up to 11,000 km (approximately 6,835 miles), enabling it to strike targets far beyond Russia’s borders, including most of Europe, the United States, and other strategic locations.
