Technical Report NASA Technical Paper Cogo, F., Weight discrepancy analysis between LAGEOS 1 and LAGEOS 2 satellites. Technical Report LG-TN-AI Aeritalia. The optical range correction (the distance between the apparent retroreflective skin of the satellite and the center of mass) of the LAGEOS 2 was determined using computer analysis of theoretical and experimentally measured far field diffraction patterns, and with short pulse lasers using both streak camera-based range receivers and more conventional PMT-based range receivers. A mode-locked freqeuncy doubled Nd:YAG laser with a pulse width of about 60 ps was used as the ranging transmitter and a crossfield photo-multiplier was used in the receiver.

Mission Objectives: LAser GEOdynamics Satellite-1 (LAGEOS) was designed by NASA and launched in It was the first spacecraft dedicated exclusively to high-precision laser ranging and provided the first opportunity to acquire laser-ranging data that were not degraded by errors originating in the satellite orbit or satellite array.   [1] The temporal spread of optical pulse signals due to reflection from multiple onboard reflectors is now a critical problem in satellite laser ranging. The full rate residual profile of single‐photon laser ranging can be used to model the response function of geodetic satellites, resolving the uncertainty of far‐field by: Degnan, JJ., Satellite Laser Ranging: Current Status and Future Prospects, IEEE Transactions on Geoscience and Remote Sensing, GE- 23, 4, –, Cited by: 8.

LAGEOS-2, based on the original LAGEOS design, was built by the Italian. The primary goal of the MAP satellite, now in orbit, is to make high-fidelity polarization-sensitive maps of the full sky in five frequency bands between 20 and GHz. From these maps we will characterize the properties of the cosmic microwave background (CMB) anisotropy and Galactic and extragalactic emission on angular scales ranging from Cited by: Prelaunch Optical Characterization of the Lager Geodynamic Satellite (LAGEOS 2) 13 Conclusions Successful campaign 1-mm precision limit is an open issue High rep. rate laser could allow determination of attitude and spin. 14 Thank you for your attention. 15 10 Hz and kHz working in parallel (interleaved mode).
