DESCRIPTION:Speaker 1: Valentina Nasti (SSM)\nTitle 1: Autonomous Vision-B
 ased Navigation for Spacecraft Proximity Operations Around Small Bodies: F
 rom Synthetic Rendering to Visual Odometry\nAbstract 1: Small body missio
 ns — targeting asteroids\, comets\, and other irregular objects — repr
 esent one of the most challenging scenarios for autonomous spacecraft navi
 gation. Unlike planetary environments\, these targets lack a priori shape 
 models\, exhibit weak and irregular gravity fields\, and offer no external
  navigation aids. Vision-based navigation using onboard cameras thus becom
 es the primary source of relative state information\, but its reliability 
 is highly dependent on illumination conditions\, surface texture\, and vie
 wing geometry.  This talk presents the research framework developed withi
 n the SPACE PhD program and UNINA Aerospace Team\, structured around two i
 nterconnected pillars. The first is a high-fidelity synthetic image genera
 tion environment built on Blender. It can make physically accurate images 
 of irregular bodies with realistic lighting\, calibrated sensor models\, a
 nd accurate orbital dynamics. The second pillar is a monocular Visual Odom
 etry pipeline for relative pose estimation during proximity operations. Pr
 eliminary results on a simulated asteroid scenario demonstrate the pipelin
 e's trajectory reconstruction capability and highlight the critical coupli
 ng between rendering fidelity and navigation performance.\nReferences 1:

 Title 2: An Introduction to Space Situational Awareness and Passive RF Sa
 tellite Tracking\nAbstract 2: Space Situational Awareness is becoming inc
 reasingly important as Earth orbit grows more congested\, dynamic\, and st
 rategically relevant. This talk will provide a broad overview of what SSA 
 is\, why it matters\, and which capabilities are needed to detect\, track\
 , catalogue\, and predict the motion of space objects. It will also discus
 s some of the main trends currently shaping the field\, including the grow
 ing role of Space Traffic Management\, the need for more resilient and per
 sistent tracking architectures\, the increasing importance of maneuver det
 ection\, and the integration of complementary sensing technologies. Within
  this broader context\, the talk will then focus on my research on passive
  radio-frequency sensing for satellite tracking. In particular\, I will in
 troduce the idea of exploiting RF signals already emitted by active spacec
 raft and using multiple receiving satellites to estimate the position and 
 velocity of the emitter through multilateration techniques based on Time D
 ifference of Arrival and Frequency Difference of Arrival measurements. The
  presentation will highlight the main opportunities and challenges of this
  approach\, including signal detectability\, receiver geometry\, measureme
 nt availability\, and its potential contribution to GNSS-resilient Space S
 ituational Awareness and Space Traffic Management architectures.\nReferenc
