The Satellite Encyclopedia (TSE) is a comprehensive digital reference work dedicated to the global satellite industry, space technology, and orbital telecommunications. Operated by Tag's Broadcasting Services (TBS), the entity is primarily recognized for maintaining one of the most extensive and long-running databases of artificial satellites, launch vehicles, and space programs in the world. Based in France, the organization serves as a critical information node for scientists, telecommunications engineers, aerospace historians, and satellite enthusiasts.
Core Mission and Operations
The primary function of The Satellite Encyclopedia is the systematic documentation of every major satellite launched since the beginning of the space age. The entity operates as a specialized knowledge management service, transitioning from its early origins as a localized Windows-based software (Winhelp edition) to a global web-based platform.
The entity?s activities focus on:
* Technical Data Aggregation: Collecting and verifying orbital parameters, mass, manufacturer details, and launch dates for thousands of individual spacecraft.
* Telecommunications Analysis: Providing detailed coverage of geostationary (GEO) satellites, specifically focusing on transponder configurations and signal coverage.
* Historical Archiving: Maintaining a chronological record of satellite programs, including failed missions and decommissioned hardware, to preserve the history of space exploration.
Products and Professional Services
The Satellite Encyclopedia offers a structured tier of products and information services designed for both professional aerospace applications and general research.
1. The Online Encyclopedia (TSE Online)
The flagship product is the web-accessible database (hosted at tbs-satellite.com), which contains over 3,000 pages of technical content. The database is categorized into several distinct search vectors:
* Satellites by Country: A comprehensive index allowing users to track the space capabilities and historical launches of specific nations.
* Satellites by Mission: Segregation of data based on the spacecraft's purpose, such as Earth observation, meteorology, military reconnaissance, or amateur radio.
* Satellites by Program: In-depth dossiers on multi-satellite constellations and long-term scientific initiatives (e.g., Inmarsat, Intelsat, Eutelsat).
* Launch Vehicle Database: Detailed specifications of the rockets used to reach orbit, including their lift capacity and launch history.
2. Digital Footprint Library
A specialized service for the telecommunications sector, this product provides visual and technical data regarding Equivalent Isotropically Radiated Power (EIRP).
* Coverage Maps: Hundreds of "footprints" (maps showing the signal strength of a satellite on the ground) are included to help broadcasters and VSAT operators determine service availability in specific geographic regions.
* GEO Charts: Summarized charts of geostationary satellites organized by orbital slot (longitude), essential for satellite dish alignment and frequency coordination.
3. Subscription Services
While a significant portion of the encyclopedia is available for free to the public, the entity provides a "Premium" or "Professional" subscription tier.
* Full Database Access: Subscribers gain access to the complete archive, including high-resolution images and restricted technical data sheets that are not available in the public version.
* Quarterly Updates: To maintain its status as a global reference, the subscription includes access to regular revisions (revised every three months) that reflect new launches and changes in orbital status.
4. Offline Editions (Winhelp / Software)
Historically, the entity has provided a standalone software version of the encyclopedia for users requiring intensive research capabilities without an internet connection. This product is preferred by professionals working in secure environments or remote areas where consistent web access is unavailable, as it places the entire multi-thousand-page document on the user's local hard drive.
Industry Impact and Use Cases
The Satellite Encyclopedia is frequently cited by major international organizations, including NASA and the Stockholm International Peace Research Institute (SIPRI), as a reliable source for satellite tracking and program history. Its services are primarily utilized for:
* Educational Research: Providing university students and faculty with verified aerospace data.
* Broadcasting Planning: Assisting telecommunications companies in identifying available satellite capacity and coverage zones.
* Strategic Analysis: Helping policy analysts track the growth of national space programs through historical launch data.
