I.Prochazka, Tech.Univ.Munich, Germany.October 27, 2008 Satellite laser ranging chain stability including Optical Detector Ground target calibration runs K.G.Kirchner, SLR Graz, private communication, Sept entire system stability ~ 0.8 mm / 5 ps year

I.Prochazka, Tech.Univ.Munich, Germany.October 27, 2008 Proposed detector features n POSITIVE - based on proven technology - extremely simple, rugged, easy to adjust - low power, low mass - acceptable timing resolution, stability, reproducibility - operates day (some SLR) and night time (~ all SLR) - overload resistant, long lifetime in space - ground HW & operation compatible with other missions n NEGATIVE - synchronous operation required (100 ns /10 us) - small additional HW required for some ground SLR (prototype is existing in our labs) - downlink data rate ~ 400 bits/s (may be reduced by scheduling strategy and optionally by coincidence )

I.Prochazka, Tech.Univ.Munich, Germany.October 27, 2008 Level of Technological maturity n Retroreflector assembly (Potsdam) - operated on board of several missions (Grace, …) - small modifications needed (central hole to host the optical detector) n Optical receiver - operated in SLR network worldwide > 10yrs OK - launched on MARS 92/96, NASA Mars Polar Lander98 - operating on Compass M1, > 18 months OK - operating on Jason-2, > 4 monthsOK

I.Prochazka, Tech.Univ.Munich, Germany.October 27, 2008 Specific accomodation requirements # 1 n Field of view of the optical assembly (retro + receiver) + / - 60 degrees from nadir un-obscured view n Detector temperature range - IDEAL caseany temperature C, stable +/- 2 C - the WORST caserange -50…+50 C n Cooling of optical receiver - total heat generated 0.15 W to 5 W depends on configuration - amount of heat depends on detector temperature range (the excess heat is used to temp.stabilize the receiver, if needed) n

I.Prochazka, Tech.Univ.Munich, Germany.October 27, 2008 Specific accomodation requirements # 2 n Functions needed to be added to ACES MWL - Gate pulse10 or 100 pps signal sync.to locat time base in ideal case selectable 10 or 100 pps - time tagging of the detector output versus local time base resolution 50 ps n Data handling / downlink services - downlink of the detected time tags - ~ 40 bits / event, => 400 bits/s or 4 kbit/s for 10 or 100pps resp. - data volume may be reduced by scheduling ~ 10 x “on demand~ 100 x coincidence?
