Brief Bio

Jan McGarry received her BA in Mathematics from Goucher College in 1974 and an MA in Applied Mathematics from the University of Maryland in 1983. Jan has worked in Satellite Laser Ranging (SLR) and Laser Altimetry since she joined NASA in 1974, developing instrument control software, software simulators, mathematical algorithms, and data analysis for ground-based, space-based and airborne systems. She started spaceborne laser altimeter work in the 1980s as part of the Mars Observer Laser Altimeter (MOLA) acquisition and tracking algorithm team. She continued altimeter work as a key member of the Mercury Laser Altimeter (MLA) and Lunar Orbiter Laser Altimeter (LOLA) algorithm teams, the Geoscience Laser Altimetry System (GLAS) software simulator team, and the GLAS flight science receiver algorithm team.  Jan also developed the algorithms and software for the Airborne Multikilohertz Microlaser Altimeter (Microaltimeter) as part of NASA’s Instrument Incubator Program.

 

Jan recently completed work on the ICESat-2/ATLAS Instrument’s Flight Science Receiver Algorithms, leading a team that developed the onboard algorithms to determine surface echoes from background noise. The implementation of these algorithms was needed to dramatically reduce the telemetry data volume to a sustainable level. ICESat-2 launched in 2018 and the mission is meeting or exceeding all of its challenging goals.

 

Jan started SLR work on the development of what is now the NASA legacy SLR systems. Around 2006 she became responsible for the development and operation of the primary ground station that successfully performed 1-way laser ranging to the Lunar Reconnaissance Orbiter (LRO) for over 5 years. Jan is currently leading the design and development work on the Space Geodesy Satellite Laser Ranging (SGSLR) systems. These systems will become NASA’s next generation of very accurate, totally automated SLR stations, replacing the current NASA legacy SLR systems that are located around the world and have been operating since the 1980s.
