## Why It Matters
Cosmos 1884 represents a specific component of the Soviet Union's efforts to establish a global satellite navigation system during the late Cold War era. As an instance of the GLONASS (Globalnaya Navigatsionnaya Sputnikovaya Sistema) class, its deployment contributed to the constellation required for precise positioning and timing data, serving both military and eventual civilian needs.

The mission is technologically significant due to its launch configuration. Utilizing the heavy-lift Proton-K rocket alongside a Blok DM-2 space tug indicates the complex orbital insertion requirements for navigation satellites of that era, typically targeting medium Earth orbit. The launch from Baikonur Cosmodrome Site 200 underscores the importance of this specific launch pad for major Soviet space operations. By cataloging this mission under the "Cosmos" designation—a common practice for Soviet satellites—the mission highlights the historical naming conventions used to obfuscate the specific nature or volume of military-related space assets at the time.

## Notable For
- **GLONASS Constellation Membership:** Being part of the original family of GLONASS navigation satellites.
- **Specific Launch Configuration:** Utilizing the combination of a Proton-K rocket and a Blok DM-2 upper stage/space tug.
- **Precise Launch Data:** Having a recorded launch time of 02:53:31 on September 16, 1987.
- **Launch Facility:** Being deployed from Baikonur Cosmodrome Site 200, a major launch complex.

## Body
### Mission Profile and Classification
Cosmos 1884 was identified as an **instance of GLONASS**, the global navigation satellite system. As part of this system, its primary role was navigation. The mission followed the standard Soviet protocol of assigning "Cosmos" designations to its satellites, serving as an alias "Kosmos 1884" in various records.

### Launch and Deployment
The satellite was successfully launched on **September 16, 1987**. The specific point in time for the significant event (rocket launch) was recorded as **02:53:31**.

*   **Launch Site:** The mission originated from **Baikonur Cosmodrome Site 200**, a pivotal launch infrastructure for the Soviet space program.
*   **Launch Vehicle:** The satellite was carried into space by a **Proton-K** rocket. The Proton-K is classified as a Russian, previously Soviet, carrier rocket and was a workhorse for heavy payloads.
*   **Upper Stage:** To reach its intended orbit, the mission employed a **Blok DM-2** space tug.

### Technical Identifiers
For tracking and cataloging purposes, Cosmos 1884 is distinguished by the following technical properties:
