Signal Processing Standing Commitee (SPSC) Charter

This charter was created April 1999.

To determine accurate laser range Center-of-Mass corrections for a variety of satellites, appropriate to the major observing configurations.

In particular, to examine the corrections necessary to transform from raw range measurements (although this Tiger Team is not concerned with station calibration, atmospheric correction or the effects of fuel consumption) to the center-of-mass of each satellite target, having regard to:

  • array transfer function
  • pulse-width and signal strength
  • receiver characteristics (single photon, multi-photon, etc.)

To determine optimum processing strategies for each case.

  • location measure in forming normal points (mean, mode, LEHM, something else)
  • role of skewness and kurtosis measures
  • filtering and trend-removal procedures

To propose procedures for recording and reporting the data required and used in determining and applying the corrections.

  • Data base used by Operational, Data and Analysis Centers
  • Station Information data base
  • Explicit data needed in ILRS NP and FR files
  • Format changes as appropriate
