Elroi Featured Body   960x500
David Palmer with ELROI: Extremely Low Resource Optical Identifier. ELROI is a license plate for your satellite; a small tag that flashes an optical identification code that can be read by a small telescope on the ground. The size of a thick postage stamp and fully autonomous, you can attach it to everything that goes into space, including small cubesats and inert debris like rocket stages, and it will keep blinking even after the satellite is shut down, reliably identifying the object from launch until re-entry.

Focus Areas

Spectral, spatial, and temporal sensing

  • Multispectral and hyperspectral imaging and analysis

Source phenomenology modeling, interpretation, and propagation

  • Low-light imaging
  • Synthetic Aperture Radar (SAR)

Data analysis, signal and image processing, and algorithm development

  • Satellite imagery analysis for scientific investigation and nuclear nonproliferation
  • Time-frequency analysis
  • Anomaly detection
  • Extraction of faint signals from cluttered backgrounds
  • Ptychography and tomography

Detector and system design

  • Development and deployment of space-based and ground-based sensing systems

Key to ISR-6 success is innovative leadership through a vigorous research portfolio, including high impact discovery science through leadership of efforts including the ChemCam and SuperCam experiments on NASA’s Mars Curiosity and Perseverance rovers, NASA’s NACHOS hyperspectral cubesat missions, the RAPid Telescopes for Optical Response (RAPTOR) array of “thinking” telescopes for time-domain astrophysics such as studying gamma-ray bursts, and ultra-low light imaging systems such as Remote Ultra-low Light Imaging (RULLI) systems. Our leadership in data-driven, mission-relevant research includes substantial accomplishments toward characterizing industrial processes, detecting changes to Earth’s surface, and measuring the impacts of climate change on Arctic sea ice. We also lead and contribute to a wide range of projects not described in open literature. Learn more at these links:
