The Resurs-P No.1 (Russian: Ресурс-П №1, where "Ресурс" means "Resource" and "П" stands for "Перспективный" or "Prospective") was the first satellite of the Resurs-P series of Russian Earth observation satellites. Operated by Roscosmos, it was designed to provide high-resolution panchromatic and multispectral imagery for a wide range of applications, contributing significantly to Russia's space-based remote sensing capabilities.
Overview
Resurs-P No.1 represented an advancement over its predecessor, Resurs-DK1, offering improved spatial resolution, increased data collection capacity, and enhanced operational flexibility. The primary mission of the Resurs-P series is to gather detailed optical imagery of the Earth's surface for various purposes, including:
- Cartography and Topography: Creating and updating detailed maps.
- Environmental Monitoring: Tracking changes in land cover, deforestation, water resources, and pollution.
- Natural Resource Management: Monitoring agricultural lands, forest health, and mineral exploration.
- Emergency and Disaster Management: Providing imagery for damage assessment and response efforts after natural disasters or technological incidents.
- Hydrometeorology: Supporting weather forecasting and climate studies.
- Infrastructure Monitoring: Observing large-scale construction projects and critical infrastructure.
Technical Specifications and Mission Details
- Launch Date: June 25, 2013
- Launch Site: Baikonur Cosmodrome, Kazakhstan
- Launch Vehicle: Soyuz-2.1b
- Operator: Roscosmos (Russian Federal Space Agency)
- Orbit: Sun-synchronous orbit, allowing for consistent illumination conditions during image acquisition.
- Main Instrument: The primary payload was the GSA (Geological Survey Apparatus) instrument complex, which included:
- High-Resolution Panchromatic Imager: Capable of resolutions down to approximately 1 meter.
- Multispectral Imagers: Capturing images in several spectral bands with resolutions of around 3-4 meters.
- Wide-Swath Multispectral Imagers: Providing broader coverage at lower resolutions (around 12-24 meters).
- Design Life: Initially designed for a operational lifespan of at least 5 years.
Operational History
Following its successful launch, Resurs-P No.1 entered into active service, delivering a continuous stream of imagery that supported both civilian and governmental needs within Russia and for international customers. The satellite successfully exceeded its design life, providing valuable data for over eight years. Its operational capabilities allowed for frequent revisits to target areas, enhancing its utility for dynamic monitoring tasks.
End of Mission
Resurs-P No.1 officially ceased its operational activities in late 2021, having completed its mission and provided extensive data throughout its service life. It was succeeded by Resurs-P No.2 and Resurs-P No.3, which continued and expanded upon the capabilities of the series.
