SLR Technology is Rapidly Advancing

Data Yield
SLR data yield has improved by a factor of three over the last six years through:
  • Real-time data processing,
  • Satellite pass interleaving,
  • System upgrades,
  • Additional operating shifts for Topex/Poseidon, and
  • Additional Satellites.

SLR data yield (1988-1993)

The Crustal Dynamics Data Information System (CDDIS), located at NASA/GSFC, is the repository for the global SLR data set. These data, both full-rate and on-site normal points, are available via electronic access and/or magnetic tape.

Mission Requirements for the SLR Network

Mission support by the SLR Network has expanded dramatically during the last ten years, for a variety of missions, and the predicted need for SLR will continue to grow in the next decade.

Taking this expanding role into account, performance and efficiency enhancements are underway:

  • On-site processing for 24-hour data availability to the users;
  • Computerization of logistics, safety, and administrative functions;
  • New system controllers to reduce operator interactions;
  • Use of Internet to facilitate communications and reduce costs;
  • Hardware upgrades to increase reliability and data quality control.
NGSLR will Reduce Station Operating Costs

NGSLR (formerly SLR 2000) is a fully automated, standardized, eye-safe, low-cost, subcentimeter system, which would replace existing manned SLR systems in the next decade. SLR 2000 is a low-cost, compact, autonomous laser ranging system for the next century.
