Area of Science:

Geodesy
Satellite Laser Ranging (SLR)
Space Geodesy

Background:

NASA's legacy satellite laser ranging (SLR) network has been vital for the International Terrestrial Reference Frame (ITRF) for over 40 years.
The existing network is nearing end-of-life, necessitating the development of new systems to meet evolving scientific demands.

Purpose of the Study:

To introduce the new generation of Space Geodesy Satellite Laser Ranging (SGSLR) systems being developed by NASA.
To outline the design, requirements, testing, and expected performance of the SGSLR systems for the NASA Space Geodesy Project (SGP).

Main Methods:

Development of nine subsystems for the SGSLR systems, focusing on robustness and 24/7 operational capability with minimal human intervention.
Designing for sub-millimeter precision ranging to meet the aggressive performance requirements of tracking numerous targets.
Leveraging lessons learned from legacy systems and a successful prototype to inform the new network's design.

Main Results:

The SGSLR systems are designed as state-of-the-art, kilohertz laser ranging systems.
The new systems aim to support the Global Geodetic Observing System (GGOS) goals for 1 mm position accuracy and 0.1 mm/year ITRF stability.
Anticipated system performance will be detailed, focusing on reliability and precision.

Conclusions:

The new SGSLR network is essential for maintaining and advancing the ITRF.
These systems will ensure continued high-precision geodetic measurements critical for global reference frames.
The SGSLR systems represent a significant upgrade in NASA's space geodesy capabilities.
