The DMC3 / TripleSat Constellation is a new satellite formation launched in July 2015 and provides data distributed by Earth-i.
It consists of 3 optical, multi-spectral satellites of high resolution, of low altitude.
- Very high resolution (1m)
- Quick retrieval and data availability
- 4 multi-spectral and panchromatic bands
- Extremely accurate georeference
- Estimated satellite lifespan – 10 years
- Maximization of visualization capabilities through Coordinated orbit
- Completion of 45 orbits per day
Applications in the Fields:
- Energy and Natural Resources
- Urban planning, spatial planning
- Navigation tracking, monitoring and tracking
- Environment – Disaster Management
