- Khz SLR systems in operation or near today!
- SLR Graz (Austria)
- Fully operational today
- 10 ps-4OO microjoules/shot-2Khz-532nm
- Some hundred K returns/pass
to LAGEOS -10K/hour on GP
- SPE for HEO satellites and power control
for LEO-RMS<3 mm
- Capability to identify single retro tracks
=> New challenge for analysts
- SLR2000 (USA) Early satellites tracking results
- Fully automated,
eyesafe, 2khz
- Star calibration and mount model OK,2 arc second
accuracy
- Ground calibrations operational, RMS still high
- Satellites engineering
passes with 60 microjoules, low return rate
=> Today tracking, still remains work, not insurmountable
with funding ...
- New stations design
- GUTS in Japan operating since spring 2004
- 50/300mj - 60/300ps
tracking LEO to GEO satellites
- remote controlled from more
than one thousand km
- Robust, efficient, accurate
- Mt. Stromlo in Australia being rebuilt quickly, more efficient
and accurate
- One year between "first stone" and
full operational capability!
- Fully automated with experts software
- Three wavelength available,
eyesafe to protected mode for the laser
- Capability to track
from very LEO satellites to the Moon
- SOS-WStromlo in Germany: A two color Kilohertz SLR system
- Fully
funded, construction in progress... operationnal to
2006!
- Day
and night two color capability from LEO to HEO satellites
- The
new generation of SLR in Wettzell !
- EOS Space Research Center at Mt. Stromlo
- Two telescopes: 1
m and 1.8 m, kw-class laser, adaptive optics
- Space debris
accurate tracking, laser ablations.
- Research collaborations
proposal to the community!
- Technology for future
- Laser (J. Degnan)
- Idea to built totally passive, multipass amplifier
for low energy oscillators(mic joules)
- Slab between two mirrors... compact,
simple to align, optic isolation, gain …
- Detector(Czech)
- Laser eyesafe ~ 1500 nm
- State of the art about detectors available
today
- Tests with Ge but difficult to operate (t°)
- InGA aS easier
but rise time and accurac !!
- Tests in progress with Ge04Si06 promising ...
- Envisat - Cryosat missions - SLR support (European SA)
- Bilan
of the missions
- Decreasing number of SLR observations along
years
- Need of SLR tracking even with DORIS
- Thanks to SLR stations for
supporting these missions!
