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
