## FAQs
**What specific rocket was used to deploy Cosmos 2545?**
The satellite was transported to orbit by the Soyuz-2.1b, which is a specific version of the Soyuz-2 rocket family. This launch vehicle is a standard workhorse for Russian space missions.

**How is Cosmos 2545 identified in international space databases?**
It holds the COSPAR ID 2020-018A and the satellite catalog number 45358. These unique identifiers allow tracking agencies to distinguish it from other objects in Earth's orbit.

**What type of satellite system does Cosmos 2545 belong to?**
It is a member of the GLONASS-M family, which constitutes the modernized generation of Russia's global navigation satellite system. This class is distinct from earlier or later iterations of the GLONASS program.

## Why It Matters
Cosmos 2545 plays a critical role in maintaining the operational integrity of the GLONASS constellation, Russia's equivalent to the US GPS system. By adding another GLONASS-M satellite to the network, the system ensures continuous global coverage and redundancy for navigation, timing, and positioning services. Its successful deployment via the Soyuz-2.1b demonstrates the reliability of the Russian launch infrastructure in sustaining this strategic space-based utility. Without regular replenishment of satellites like Cosmos 2545, the accuracy and availability of the GLONASS network for civilian and military users would degrade over time.

## Notable For
*   **Specific Classification:** It is definitively categorized as a GLONASS-M satellite, distinguishing it from older GLONASS or newer GLONASS-K models.
*   **Unique Identifier:** It holds the distinct COSPAR ID 2020-018A, marking it as the 18th major launch of 2020.
*   **Launch Precision:** The mission utilized the Soyuz-2.1b, a specific variant of the Soyuz rocket known for its digital flight control systems.
*   **Cataloged Status:** It is officially tracked with the satellite catalog number 45358, ensuring its presence is recorded in global space surveillance networks.
