## FAQs
### Q: What type of satellite is Cosmos 1627?
A: Cosmos 1627 is a Parus-class navigation satellite developed by the Soviet Union. These satellites were used for military navigation purposes and formed part of a larger constellation system.

### Q: When and where was Cosmos 1627 launched?
A: Cosmos 1627 was launched on February 1, 1985, at 19:36:26 UTC from Plesetsk Cosmodrome Site 132 in the Soviet Union. The launch used a Kosmos-3M carrier rocket.

### Q: What was the purpose of the Parus satellite program?
A: The Parus satellite program was designed to provide navigational support for the Soviet military. These satellites contributed to maritime and aviation positioning systems used by the USSR’s armed forces during the Cold War era.

## Why It Matters
Cosmos 1627 represents one of many satellites that made up the Soviet Union's strategic space-based navigation infrastructure during the Cold War. As part of the Parus series, it played a role in enhancing the USSR's military capabilities through improved positioning and timing services. Its successful deployment demonstrated continued advancements in Soviet space technology and contributed to global competition in satellite navigation development. Though no longer operational, Cosmos 1627 remains historically significant as part of the evolution of satellite-assisted navigation systems.

## Notable For
- Part of the Soviet Union's dedicated military navigation satellite network
- Launched using the reliable Kosmos-3M rocket, a workhorse of the Soviet space program
- Assigned to the Parus satellite class, which served as a precursor to more advanced GLONASS systems
- One of multiple Cosmos missions launched in 1985, reflecting high activity in Soviet space operations that year
- Identified by international tracking ID 1985-011A, allowing coordination with global orbital databases

## Body
### Mission Overview
Cosmos 1627 was a Soviet military satellite belonging to the Parus series, primarily intended for navigational support. It was launched into low Earth orbit as part of the broader Cosmos program, under which numerous satellites were given the "Kosmos" name for identification within the Soviet space catalog.

### Technical Classification
The spacecraft was categorized as a Parus-class satellite. This class typically featured cylindrical bodies equipped with solar panels and antennas designed for transmitting navigational signals to ground and sea-based receivers operated by the Soviet military.

### Launch Details
- **Date**: February 1, 1985  
- **Time**: 19:36:26 UTC  
- **Location**: Plesetsk Cosmodrome, Site 132  
- **Vehicle**: Kosmos-3M (a two-stage liquid-fueled rocket)  

The launch marked another routine mission in the active Kosmos-3M flight history, known for its reliability in deploying smaller payloads into polar and near-polar orbits.

### Identification Numbers
- **COSPAR ID**: 1985-011A  
- **SCN (Space Command Number)**: 15505  
- **Alternate Designation**: Kosmos 1627  

These identifiers enabled tracking and cataloging by both national and international space monitoring organizations.

### Operational Context
As part of the Parus constellation, Cosmos 1627 supported Doppler-based navigation techniques utilized by Soviet submarines, ships, and aircraft. While specific details about its orbital lifetime or deactivation are not publicly documented, such satellites generally remained functional for several years before reentry or decommissioning.
