ITPS - Introduction

• Purpose
• Acquisition, compilation, storage, extraction and
  analysis of SDO housekeeping telemetry data.
• Usage
• Gives FOT access to full resolution archive of
  all housekeeping data points (mnemonics).
• Reduced resolution statistical archive serves as
  basis for trend determination.
• Generation of reports, plots and tables using
  precise analysis and mining capabilities.
• Key Features
• Complete end-to-end automation reduces FOT burden
  
• Web access gives remote authorized users access
  to ITPS.
• GOTS
• First developed on behalf of Landsat 7 and SOHO,
• Trending solution for Landsat 5, Landsat 4
  (historical data), Wind, POLAR, ST-5, LRO, TRMM,
  GLAST, Landsat 7, JWST (prototype)
