Technological maturation of a CMOS gigapixels astrometry instrument for Habitable World Observatory space mission

8 July 2026 • 16:40 - 17:00 CEST | Room B4-M3

Abstract

To meet its demanding the Habitable Worlds Observatory (HWO) astrometric goals, a dedicated high-precision instrument is being developed around a gigapixel-class focal plane using Pyxalis’s new 220-MP GigaPyx CMOS sensors and an integrated calibration system. The project addresses three main challenges: validating detector performance, developing space-qualified packaging for a multi-sensor focal plane, and implementing on-board processing capable of reducing data volume by a factor of ~100. The maturation plan includes building a complete end-to-end detection chain to reach TRL 5 by the end of the program for the Mission Consolidation review in 2029.

Technical Director of the Astrophysics Department, I am specializing in advanced instrumentation for space science. I have led developments of detector subsystems for astrophysics, including work on the ISGRI camera for INTEGRAL and preliminary design phase of the JSWT /MIRIM. I have also managed technical projects in neutrino physics. My work focuses on project management, detector technologies, and preparing innovative instruments for future observatories.
