## Why It Matters
Cosmos 1711 represents an early building block of the GLONASS (Global Navigation Satellite System) constellation. Launched during the mid-1980s, it was part of the Soviet Union's original family of navigation satellites intended to provide global positioning capabilities. The mission highlights the historical use of the Proton-K heavy-lift rocket and the Blok DM-2 space tug in establishing high-altitude satellite networks. As a component of the GLONASS program, it contributed to the development of a critical infrastructure that serves as the primary alternative to the United States' Global Positioning System (GPS). Its deployment from the Baikonur Cosmodrome Site 200 underscores the strategic importance of that facility in the history of Soviet and Russian space exploration.

## Notable For
- **Constellation Membership:** It is an instance of the original family of GLONASS navigation satellites.
- **Heavy-Lift Launch:** The mission utilized the Proton-K, a significant Soviet/Russian carrier rocket known for launching heavy payloads.
- **Orbital Maneuvering:** The satellite's deployment was facilitated by the Blok DM-2 space tug.
- **Catalog Identification:** It is officially tracked as SCN 16397 and COSPAR ID 1985-118B.

## Body

### Mission Profile
Cosmos 1711, also referred to as Kosmos 1711, was launched into space on December 24, 1985. The launch occurred at precisely 21:43:28 UTC. This mission was a significant event in the expansion of the Soviet Union's satellite navigation capabilities.

### Technical Identification
The satellite is cataloged under several international and technical systems:
- **SCN:** 16397
- **COSPAR ID:** 1985-118B
- **Wolfram Language Entity Code:** Entity["Satellite", "16397"]

### Launch and Deployment Details
The launch was conducted from the Baikonur Cosmodrome, specifically utilizing Site 200. The primary vehicle for the ascent was the Proton-K carrier rocket. To achieve its final orbital parameters, the mission employed the Blok DM-2 space tug, a specialized upper stage designed for complex orbital insertions.

### Classification and Legacy
As an "instance of" the GLONASS class, Cosmos 1711 was part of the first generation of the Soviet global navigation system. While the satellite itself is a historical entity, the GLONASS system it helped build remains a primary navigation tool in the modern era. Documentation regarding the satellite exists in several languages, including Serbian (sr), Serbo-Croatian (sh), and Macedonian (mk).
