Abstract

Système de détection d'au moins un objet spatial (B) dans l'environnement d'un satellite dit satellite porteur (C), le système comprenant: - un dispositif de réception (DR) de signaux émis par un système de navigation par satellites dits satellites GNSS, embarqué à bord dudit satellite (C); et - un dispositif de détection (DD) configuré pour mettre en œuvre un traitement de réflectométrie de signaux émis par le système de navigation par satellites GNSS et détecter la présence d'un objet spatial (B) dans l'environnement du satellite porteur (C) à partir d'au moins une mesure de signaux reçus par le dispositif de réception (DR) dudit satellite porteur (C), émis par au moins un satellite GNSS (A1, A2, A3) et reçus par un trajet direct (S1, S2, S3) et par un trajet réfléchi (S'1, S'2, S'3) sur l'objet spatial (B). Figure pour l’abrégé : Fig.1System for detecting at least one space object (B) in the environment of a satellite called a carrier satellite (C), the system comprising: - a device for receiving (DR) signals transmitted by a satellite navigation system said GNSS satellites, on board said satellite (C); and - a detection device (DD) configured to implement reflectometry processing of signals transmitted by the GNSS satellite navigation system and to detect the presence of a space object (B) in the environment of the carrier satellite (C ) from at least one measurement of signals received by the reception device (DR) of said carrier satellite (C), transmitted by at least one GNSS satellite (A1, A2, A3) and received by a direct path (S1, S2, S3) and by a reflected path (S'1, S'2, S'3) on the space object (B).
