Dear Laser Tracking Colleagues,
G'Day from Tokyo.
In the 21st International Workshop on Laser Ranging (conference site: http://www.iwlr2018.serc.org.au/, proceedings site: https://cddis.nasa.gov/lw21/Program/index.html, I presented station-by-station performance charts (printed on 1-metre-long sheets) during the Clinic Session 3 co-hosted with Jose Rodriguez. Here are the short summary of the analysis and the links to the charts.
Period: July 2017 to June 2018.
Satellites: LAGEOS-1, LAGEOS-2, AJISAI, STARLETTE, STELLA and LARES.
29 Stations with > 200 LAGEOS passes in the 1 year span.
More details about the analysis: See http://geo.science.hit-u.ac.jp/slr/bias/2018sp/Clinic_Booth3.pdf
Unlike the previous years' ones, this year's charts are organised PER STATION. Matrix charts are also provided (printed on the reservse side) to help investigate the cause.
The first part contains:
Residual wrt Range rate (negative in ascending (first) half, and positive in descending (second) half of a pass)
Residual wrt Local time (defined by the station longitude, slightly different from the local standard time)
Residual wrt Range rate (as specified in normal point data)
Residual wrt Single-shot RMS (as specified in normal point data)
Residual wrt Skew (as specified in normal point data)
Residual wrt Kurtosis (as specified in normal point data)
Residual wrt System delay (1), (2),.. (per system delay 'group')
System delay (all sat) (including calibration data for other satellites not included in this analysis)
System delay (A), (B), ... (vertical scale magnified as above)
Calibration interval (cumulative) (typical calbration interval is at median (50%))
The matrix chart (second part) labels, top-to-botumn = left-toright, mean:
Mon 17: Months from January 2017 (13 for January 2018)
Hour: Local time
# ret: Number of returns per NP bin
Return rate
RMS: Single-shot RMS
Skew
Kurt: Kurtosis
Range rate
System delay (1), (2), ...
O-C: POD residuals
