## Why It Matters
Cosmos 2177 represents a key component in the development and maintenance of the GLONASS satellite navigation system, which serves as Russia’s counterpart to the U.S. Global Positioning System (GPS). As part of a network that provides accurate geolocation and time information globally, Cosmos 2177 contributes to critical infrastructure for transportation, telecommunications, defense, and scientific research. Its deployment marked continued Soviet-era advancements in space-based navigation technology, later inherited and maintained by the Russian Federation. Satellites like Cosmos 2177 ensure dual-system redundancy for users worldwide, enhancing reliability and precision in global navigation services.

## Notable For
- Part of the original GLONASS constellation developed during the Soviet era
- Launched aboard one of the most reliable heavy-lift rockets in history, the Proton-K
- Represents continuity in Russian satellite navigation capabilities post-Soviet Union
- Operated with the Blok DM-2 space tug, known for precise orbital insertion
- Identified in multiple international databases including Wolfram Alpha (Entity["Satellite", "21853"])

## Body
### Mission Overview
Cosmos 2177 was launched as part of the GLONASS program, a global navigation satellite system developed initially by the Soviet Union and now operated by the Russian Aerospace Forces. Designed to function alongside other GLONASS satellites, it contributes to providing continuous radio-navigation signals for determining position, velocity, and time across the globe.

### Technical Specifications
- **Satellite Class**: GLONASS navigation satellite  
- **Launch Mass**: Approximately 1,400 kg (typical for early GLONASS models)  
- **Orbital Regime**: Medium Earth Orbit (MEO)  
- **Constellation Role**: Operational support within GLONASS orbital planes  

### Launch Details
The satellite was successfully launched on **January 29, 1992**, at **22:19:12 UTC** from **Site 81/23** at the **Baikonur Cosmodrome**, Kazakhstan. The mission utilized the **Proton-K** launch vehicle, augmented by the **Blok DM-2** upper stage, which enabled precise orbital delivery into its designated slot within the GLONASS constellation.

### Programmatic Context
