Mission Details

Pléiades-Néo 4

Pléiades-Néo, initially also known as VHR-2020, is a four-satellite very high-resolution earth observation satellite constellation by Airbus Defence & Space designed as a follow-on to the Pléiades-HR satellites.

The satellites will feature an imager with 30 cm ground resolution, possibly featuring CILAS deformable mirrors. They will use TesatSpacecom laser communication relay terminals to transfer data via the EDRS network, enabling near-real-time access to the images.

The Pléiades-Néo constellation will use a 700 km orbit with two orbital planes to allow intra-day revisit times.
