Role within the Space Array roadmap

SHARP can be presented as a focused, scientifically compelling step toward the broader Space Array vision. It helps define the requirements, technologies, calibration strategies, and operational concepts needed for a future distributed observatory.

Key themes

  • High-frequency space VLBI and black-hole imaging.
  • Precision baseline knowledge and orbit reconstruction.
  • Calibration using astronomical sources and supporting metrology.
  • Data handling, correlation, imaging, and science exploitation.
