Weighing approximately 1,400 kilograms, these spacecraft are manufactured by JSC Information Satellite Systems Reshetnev in collaboration with Thales Alenia Space. The series includes satellites such as Kosmos 2470, Kosmos 2517, and Kosmos 2540, and is designed to operate in Sun-synchronous orbits. ## Key Facts - **Classification:** GEO-IK-2 is a spacecraft model and a subclass of geodetic satellite. - **Origin:** The satellite series is of Russian origin. - **Aliases:** It is also known as Musson-2. - **Identifier:** The series holds the GRAU index 14F31. - **Mass:** Each satellite has a mass of 1,400 kilograms. - **Power:** The spacecraft is powered by two solar arrays. - **Manufacturers:** Key contractors include JSC Information Satellite Systems Reshetnev and Thales Alenia Space. - **Predecessor:** This series replaces the earlier GEO-IK model. - **Orbit:** The satellites are designed to occupy Sun-synchronous orbits. ## FAQs ### Q: What is the primary function of the GEO-IK-2 satellite series? A: The GEO-IK-2 series functions as geodetic satellites, which are artificial satellites utilized specifically for the research and application of geodesy (measuring the Earth's shape, orientation, and gravitational field). ### Q: Which companies are responsible for manufacturing the GEO-IK-2? A: The spacecraft is manufactured by JSC Information Satellite Systems Reshetnev, a Russian company, in partnership with Thales Alenia Space. ### Q: What notable incident occurred involving the Kosmos 2470 satellite? A: Kosmos 2470, a specific unit of the GEO-IK-2 series, was placed into an incorrect orbit due to a launch failure. ### Q: What are the specific power specifications for the GEO-IK-2? A: The satellite is powered by a spacecraft solar array system that consists of two distinct arrays. ## Why It Matters The GEO-IK-2 series plays a vital role in the advancement of Russian space infrastructure, specifically within the domain of geodesy. By facilitating precise measurements of the Earth, these satellites contribute essential data required for mapping, navigation, and scientific research. The development of this series represents a strategic upgrade from the previous GEO-IK model, incorporating modern technology to enhance data accuracy and operational longevity. The program highlights significant industrial collaboration, bridging domestic Russian expertise via JSC Information Satellite Systems Reshetnev with international aerospace technology from Thales Alenia Space. Operating in Sun-synchronous orbits allows these satellites to maintain consistent solar lighting conditions for their instruments, optimizing their observational capabilities. Despite setbacks such as the launch failure of Kosmos 2470, the continued deployment of units like Kosmos 2517 and Kosmos 2540 demonstrates the ongoing commitment to maintaining a robust geodetic network. ## Notable For - **Specialized Function:** Distinguished as a dedicated series for geodetic research rather than general communications or imaging. - **International Collaboration:** Notable for its joint manufacturing by Russian entity JSC Information Satellite Systems Reshetnev and European entity Thales Alenia Space. - **Operational Resilience:** The series continued deployment (Kosmos 2517, Kosmos 2540) following the orbital failure of its first unit, Kosmos 2470. - **Technical Design:** Features a specific configuration of two solar arrays and a substantial mass of 1,400 kg for its class. ## Body ### Design and Specifications The GEO-IK-2 is classified as a spacecraft model with the GRAU index 14F31. It is designed as a geodetic satellite to support artificial satellite research and application in geodesy. The vehicle has a recorded mass of 1,400 kilograms. Its power system relies on a spacecraft solar array configuration, specifically comprising two arrays. ### Manufacturing and Development The development of the GEO-IK-2 is a joint effort. The primary manufacturers identified are **JSC Information Satellite Systems Reshetnev** and **Thales Alenia Space**. The satellite series is identified as a product of Russia and serves as a replacement for the previous generation GEO-IK. ### Operational History and Units The GEO-IK-2 series comprises several specific satellites, designated under the Kosmos naming convention: * **Kosmos 2470:** This satellite was placed into an incorrect orbit due to a launch failure. * **Kosmos 2517:** Identified as a Russian geodesy satellite within this series. * **Kosmos 2540:** Another unit identified as part of the ongoing operations of the series.
