Station performance charts (Potsdam Workshop Spoiler)
« on: September 20, 2016, 05:03:20 PM »
Hello from Tokyo.

Just 2 weeks before the Potsdam workshop, we have generated a huge number of station-by-station charts so as to assess+assist the productivity and the quality of every SLR station. 

The details are introduced in the 'systematics' session and the 'clinic' session, but you will be able to directly get to the points if you look at them in advance.

This year, in addition to the usual tests, we look into the calibration (= system delay measurement) - frequency, stability, etc.

// Data span: 1 year = July 2015 to June 2016
// POD: software c5++ R874

Hit-rate (observation success rate) over all fly-over observation chances (El > 20 deg)
(Pages 3 and 5 are just rescaled-without-Yarragadee version of Pages 2
and 4 resp)

LAGEOS-1+2 NP Post-POD RMS vs Session-by-session system delay RMS
(Page 1 >> ZOOM >> Page 2 >> ZOOM >> Page 3)

System delay time series
(1 year span)
(5 day span; one of densely observed periods)

System delay measurement frequency
= Interval between calibration record with different time tags
(blue parts: not a unique measurement? Identical records with different time tags found.)
(X-axis extended for 1824, 1873, 1884 and 7820)

Range bias vs System delay

Range bias vs Intensity (# of returns per NP)

Range bias vs Single-shot RMS

Range bias vs Sun Elevation (day vs night)

See you soon in Potsdam,
