On February 2, 2015, the proven Safir-1B satellite carrier launched from the Semnan Space Center in Semnan Province, successfully injecting Dawn (Fajr in Persian) —Iran's innovative research satellite—into an elliptical low Earth orbit with a perigee of 224 kilometers and apogee of 470 kilometers at a 55.53° inclination.
Developed by the Iranian Space Agency (ISA) in partnership with domestic engineering teams, this 52-kilogram hexagonal prism satellite introduced groundbreaking advancements in propulsion and imaging. As a key demonstrator on Iran's national space day, Fajr achieved full telemetry within hours of deployment, validating its role in transitioning from research to operational orbital capabilities.
Now, 10 years post-launch, Fajr's technologies continue to influence Iran's satellite ecosystem, enabling enhanced maneuverability and data acquisition that drive efficiency and scalability in modern space missions.
The Mission: Propulsion and Imaging from Elliptical Heights
Fajr serves as a research and technology demonstrator satellite, focused on validating propulsion systems and basic Earth observation for future operational platforms. Its pioneering features include:
- Cold Gas Thruster: Iran's first onboard propulsion, enabling orbit circularization and attitude adjustments for extended mission control.
- Optical Imaging Payload: 500-meter resolution camera for environmental monitoring and land use analysis.
- Experimental GPS Receiver: Locally developed navigation system for precise tracking and positioning.
- Solar-Powered Design: Deployable panels ensuring reliable energy for 1.5-year planned operations in dynamic orbital environments.
