Perteo: Persistent Real-Time Earth Observation Small Satellite Constellation for Natural Disaster Management

Abstract

PERTEO is a mission proposal intended to provide real-time EO services to reduce Natural Disaster impact by proposing a heterogeneous small satellite constellation and performing in-orbit processing. For that aim, this mission takes advantage of the enhanced capabilities of AI edge processing by enabling on-demand user services through the "satellite as a service" concept. The design of the constellation includes three types of sensors: SAR, Hyperspectral and Multispectral imager VHR combining their capabilities to achieve almost real-time due to their in-orbit distances. Six spacecrafts are considered in each orbit organized in pairs (180° phased platforms) mounting the same instrument. The proposed solution is responsive achieving almost real-time latencies ( Ex: < 1 min, down to seconds is achieved in the first observation product). Persistence is achieved with a low revisit time (< 1 hour any payload; < 3 hour s any specific payload choice).
