## FAQs
### Q: What type of satellite was Cosmos 1064?
A: Cosmos 1064 was a Parus-class navigation satellite, part of the Soviet Union's maritime navigation system designed to provide positioning data for ships and submarines.

### Q: When and where was Cosmos 1064 launched?
A: Cosmos 1064 was launched on December 20, 1978, at 20:43:00 UTC from Site 132 at the Plesetsk Cosmodrome in the Soviet Union.

### Q: What rocket was used to launch Cosmos 1064?
A: The satellite was launched using a Kosmos-3M rocket, a Soviet-era launch vehicle that was commonly used for deploying small satellites into low Earth orbit.

## Why It Matters
Cosmos 1064 represents an important component of the Soviet Union's Parus navigation satellite system, which was the Soviet equivalent to the U.S. Transit navigation satellites. These satellites provided critical positioning and timing data for Soviet naval vessels, particularly submarines, enabling more accurate navigation in the vast expanses of the world's oceans. The Parus system was part of the broader Soviet effort to achieve technological parity with Western navigation capabilities during the Cold War era. By providing reliable positioning data to naval forces, Cosmos 1064 and its sister satellites enhanced the Soviet Union's maritime operational capabilities and contributed to the strategic balance of power during a period of intense technological competition between the superpowers.

## Notable For
- Part of the Soviet Parus navigation satellite constellation
- Launched using the reliable Kosmos-3M rocket
- Provided maritime navigation services to Soviet naval forces
- Operated during the height of the Cold War space race
- Represented Soviet technological achievement in satellite navigation

## Body
### Technical Specifications
Cosmos 1064 was a Parus-class satellite, which were medium-sized navigation satellites typically weighing several hundred kilograms. These satellites operated in low Earth orbit and were equipped with radio transmitters that broadcast navigation signals.

### Launch Details
The satellite was launched from Plesetsk Cosmodrome, the primary Soviet military launch site located in northern Russia. Site 132 was specifically designed for Kosmos-3M launches. The launch occurred at 20:43:00 UTC, placing the satellite into its intended orbit.

### System Context
The Parus system (meaning "sail" in Russian) was the Soviet counterpart to the U.S. Transit system. Unlike GPS, which provides continuous global coverage, the Parus system required multiple satellites to provide periodic coverage, with users needing to wait for the next satellite pass to obtain a position fix.

### Operational Role
As a navigation satellite, Cosmos 1064 would have transmitted radio signals that allowed surface vessels and submarines to determine their position by measuring the Doppler shift of the received signals and tracking the satellite's orbit. This capability was crucial for Soviet naval operations, particularly for ballistic missile submarines that needed accurate positioning for targeting.

### Historical Context
The launch of Cosmos 1064 in 1978 occurred during a period of intense space competition between the Soviet Union and the United States. The satellite's successful deployment demonstrated continued Soviet capability in space-based navigation technology, contributing to the strategic balance during the Cold War.
