## Why It Matters
Cosmos 2004 represents a significant component of the Soviet Union's integrated space-based navigation infrastructure during the Cold War era. As a Parus-class satellite, it contributed to the Soviet maritime navigation system that provided critical positioning, timing, and communication services for naval vessels, submarines, and commercial shipping. This satellite was part of a larger constellation that enabled the Soviet Union to maintain independent navigation capabilities outside of Western-controlled systems like GPS. The successful deployment of Cosmos 2004 demonstrated the Soviet Union's continued advancement in space technology and its commitment to maintaining strategic military and commercial navigation capabilities. These satellites played a crucial role in extending Soviet naval reach and ensuring operational effectiveness of maritime forces across global oceans.

## Notable For
- Part of the Parus navigation satellite system that provided Soviet maritime forces with independent positioning capabilities
- Launched using the reliable Kosmos-3M rocket, which had a strong track record for military and scientific satellite deployments
- Contributed to the Soviet Union's strategic goal of maintaining autonomous navigation infrastructure separate from Western systems
- Operated during the final years of the Cold War, representing the technological capabilities of the Soviet space program
- Successfully integrated into the existing Parus constellation, enhancing coverage and reliability of Soviet maritime navigation services

## Body
### Technical Specifications
Cosmos 2004 was a Parus-class navigation satellite, which typically weighed around 325-400 kg and operated in a medium Earth orbit at approximately 1,000 km altitude. These satellites were designed for a operational lifetime of 2-3 years and carried atomic clocks for precise timing signals.

### Launch Details
The satellite was launched on February 22, 1989, at exactly 03:28:49 UTC from Site 132/1 at the Plesetsk Cosmodrome, a major Soviet and Russian spaceport located approximately 800 km north of Moscow. The Kosmos-3M rocket, a proven two-stage launch vehicle, successfully delivered the satellite to its intended orbit.

### Operational Role
As a Parus satellite, Cosmos 2004 provided navigation, positioning, and timing services specifically tailored for maritime applications. The system allowed Soviet naval vessels and submarines to determine their precise location without relying on Western navigation systems. These satellites transmitted signals that ships could use to calculate their position with accuracy suitable for both military operations and commercial navigation.

### System Integration
Cosmos 2004 was part of a larger constellation of Parus satellites that operated in specific orbital planes to ensure continuous global coverage. The satellites worked together to provide redundancy and improved accuracy, with ground control stations monitoring and maintaining the constellation's operational status.
