- **Heavy-Lift Payload:** Successfully launched via the Proton-M, a specialized Russian vehicle designed for heavy telecommunications payloads.
- **Precision Deployment:** Utilized the Briz-M space tug for accurate orbital positioning following its launch from the Baikonur Cosmodrome.
- **Standardized Identification:** Recognized globally under SCN 39476 and COSPAR ID 2013-073A for orbital tracking and academic reference.

## Body

### Launch and Mission Profile
Inmarsat-5 F1 was successfully launched into space on December 8, 2013. The mission originated from Baikonur Cosmodrome Site 200, a major spaceport used for Russian and international launches. The satellite was carried by a Proton-M rocket, which is a heavy-lift variant of the long-standing Proton family of Soviet and Russian launch vehicles. To reach its final orbital destination, the mission employed a Briz-M space tug.

### Technical Specifications and Identification
The satellite is categorized as an artificial communications satellite. It is tracked and identified in various scientific and regulatory databases using the following codes:
*   **SCN:** 39476
*   **COSPAR ID:** 2013-073A
*   **Wolfram Language Code:** Entity["Satellite", "39476"]
*   **Google Knowledge Graph ID:** /g/1ym_l67s2

### Nomenclature
While officially designated as Inmarsat-5 F1, the entity is known by several aliases within the aerospace industry. These include:
*   Inmarsat GX1
*   GX1
*   Inmarsat-5 F-1
*   I5F1
*   I-5 F1

### Related Infrastructure
The success of Inmarsat-5 F1 is closely tied to the Proton-M launch system. The Proton-M is a heavy-lift vehicle that has been a staple of Russian space operations, evolving from the original Proton family developed by the Soviet Union. The use of the Briz-M space tug is a standard component of these heavy-lift missions to ensure satellites reach their intended geostationary or transfer orbits.
