Simon Matin (University of New Mexico). Project: “Avoiding Spaceborne Radio Frequency Interference for Astronomical Observations”. NASA mentors: Dr. Nlingi Habana (SAIC@ Code 61A) & Lawrence Hilliard (NASA SGP VLBI Technologist).
Joshua Batstone ( University of Maryland, College Park )
Project: "Star image Analysis for Lunar Laser Ranging (LLR)" Worked both virtually and onsite with NASA Mentor Evan Hoffman (Code 61A), and Dr. Russet Macmillan ( Apache Point LLR Observatory, New Mexico) to develop improved software to aid in the calibration of star images for use at Apache Point during LLR.
Joseph Skeens. ( University of Texas at Austin): Project: “Automated detection of spurious signals in VLBI phase calibration data”. Worked onsite with NASA mentor, VLBI scientist Leonid Petrov (Code 61A) as an SAIC summer intern. Joe is a Ph.D Student at the University of Texas at Austin, and his advisor is Dr. Srinivas Bettadpur.
Ludvig Rodung & Tuss Anzelius ( Chalmers University, Sweden),
hosted in Greenbelt by NVI inc. Project: “Deriving gaussian models for (radio) sources”.
Worked with John Gipson (NVI @ Code 61A, NASA GSFC), IVS Analysis Coordinator and leader of the NVI VLBI group for the NASA Space Geodesy Project.
We hope the in situ and virtual experiences were enjoyable for the interns. All the interns who were in the Greenbelt area were at some time able to interact in person with the NASA scientists, and also visit the Goddard Geophysical and Astronomical Observatory (GGAO) . The GGAO is one of the handful of sites in the world that hosts all four geodetic techniques, and is critical for the maintenance of the International Terrestrial Reference Frame (ITRF).
The laboratory performs broad research, in the areas of Earth time variable and static geopotential and geomagnetic fields, Earth orientation, surface deformation, characterization and change, tides, land ice mass evolution, global and regional sea level, and airborne and spaceborne laser altimetry. The laboratory also supports many NASA missions in fundamental and core capabilities including satellite radar and laser altimetry precise positioning, pointing, ranging, timing, geolocation and calibration and validation. The laboratory is a leader in the design, development, implementation and application of airborne and spaceborne geodetic laser altimeter technology and instruments including NASA’s Land, Vegetation, and Ice Sensor (LVIS) and the Global Ecosystem Dynamics Investigation Lidar (GEDI). The laboratory is the home of the Space Geodesy Project which encompasses the management, development, operation and maintenance of NASA’s Space Geodetic Network that is comprised of the four major space geodetic observing systems: Very Long Baseline Interferometry (VLBI), Satellite Laser Ranging (SLR), Global Navigation Satellite System (GNSS), and the Doppler Orbitography and Radio-positioning by integrated Satellite (DORIS) system. It is also home to the Crustal Dynamics Data Information System dedicated to the archive and distribution of space geodesy related data sets; as well as the home to GEODYN, NASA’s state-of-the-art geodetic parameter estimation and precision orbit determination system.
