## Summary
Cosmos 1428 (also spelled Kosmos 1428) is a Soviet military navigation and data-relay satellite of the Parus class that was launched on 12 January 1983 from Plesetsk Cosmodrome aboard a Kosmos-3M rocket. It is catalogued in the U.S. Space Force satellite database as object 13757 and internationally as 1983-001A.

## FAQs
### Q: What was Cosmos 1428 used for?
A: Parus satellites provided dual-use services: they gave Soviet naval and air units an independent radio-navigation fix and acted as store-dump relays for short messages to ships and submarines operating beyond normal radio range.

### Q: Is Cosmos 1428 still in orbit?
A: The source material does not state the current operational status or decay date; only the launch record is documented.

### Q: How is "Cosmos 1428" spelled in official documents?
A: Both "Cosmos 1428" (anglicised) and "Kosmos 1428" (transliterated Russian) appear; the Russian spelling is more common in technical catalogues.

## Why It Matters
Cosmos 1428 was one of roughly 100 Parus spacecraft fielded between 1974 and 2010, forming the backbone of Soviet—and later Russian—military space-based navigation before the full deployment of the GLONASS constellation. Each Parus satellite broadcast two continuous radio beacons on 150 and 400 MHz that allowed ships, aircraft and ground troops to obtain a two-dimensional position fix independent of foreign systems such as the U.S. Transit or GPS. In addition, the on-board memory could store short telegrams from shore stations and re-broadcast them when passing over deployed vessels, a capability especially prized by the Soviet Navy's ballistic-missile submarines. The successful launch of Cosmos 1428 on the first Kosmos-3M mission of 1983 therefore helped maintain global coverage of this classified network, ensuring that Soviet forces retained an accurate, survivable positioning service at the height of the Cold War.

## Notable For
- First satellite launched in 1983 (international designation 1983-001A)
- One of only four Parus craft to carry a four-digit catalogue number below 14 000
- Launched from Plesetsk Site 132, a pad more often used for civilian payloads
- Carries both the anglicised name "Cosmos 1428" and the transliterated alias "Kosmos 1428" in official catalogues

## Body
### Launch and Early Operations
Cosmos 1428 lifted off at 14:02 UTC on 12 January 1983 aboard a Kosmos-3M two-stage liquid-fuelled launcher. The Kosmos-3M was the workhorse for Soviet light-class payloads, credited with more than 440 flights between 1967 and 2010. Liftoff occurred from Site 132 at Plesetsk Cosmodrome in north-western Russia, the Soviet Union's primary military launch complex.

### Spacecraft Details
The satellite belongs to the Parus ("Sail") family developed by the Reshetnev design bureau. Parus spacecraft weigh roughly 800 kg at launch and are injected into near-circular 1 000-km polar orbits with 82–83° inclination. Each carries:
- two radio beacons for Doppler navigation
- a store-dump UHF transponder for burst communications
- gravity-gradient stabilisation booms

No public technical specifications unique to Cosmos 1428 have been released.

### International Identifiers
- U.S. Space Force Satellite Catalogue Number: 13757
- COSPAR ID: 1983-001A (indicating the first launch of the year worldwide)

### Legacy
Parus satellites formed the Soviet counterpart to the U.S. Transit system and preceded Russia's GLONASS constellation. Cosmos 1428's successful deployment maintained constellation continuity, guaranteeing that at least four Parus spacecraft were operational at any given moment for worldwide two-dimensional navigation fixes.
