Abstract: At JPL, there is a long history of developing space flight projects for studying the Earth, the solar system, and beyond.Ìý For the past 20 years at JPL, I’ve worked on many Earth-observing flight missions, allowing me to combine my past research experience in precision orbit and attitude determination with developing and launching spaceflight missions. I’ll give an overview of what it takes to get a payload and spacecraft prepared for orbit, and give some examples with the BlackJack and TriG space Global Navigation Satellite System (GNSS) receivers from prior years.
The Cion is the next generation of GNSS science receiver being developed at JPL. Work is ongoing now to prepare the Cion for launch on two upcoming missions, Navigation Technology Satellite-3 (NTS-3) and Sun Radio Interferometer Space Experiment (SunRISE).Ìý NTS-3 is an experimental navigation satellite that will be used to help develop and validate future GPS technologies. SunRISE is a constellation of six 6U smallsats in a 10 km sphere that will provide interferometric imaging of the sun to study coronal mass ejections. Both of these missions will be in a geosynchronous orbit, above the GNSS constellations, providing an extra challenge for positioning using GNSS. I’ll give an overview of these missions and how we plan to use the Cion receiver for satellite navigation.
Bio: Dr. Angela Reichert Dorsey received her BS in Aerospace Engineering from the University of Alabama in 1993.Ìý She received her MS and PhD from the University of Colorado in 1995 and 1999.Ìý Since 2000, she has worked at NASA Jet Propulsion Laboratory, California Institute of Technology.Ìý In her more than twenty years at JPL, she has worked on numerous flight projects as a GPS subject-matter expert including Jason-1, Ocean Surface Topography Mission, GRACE, COSMIC-2, Jason-3, GEDI, Deep Space Atomic Clock, Sentinel-6, as well as other missions current being planned and developed. Her research areas include precise GNSS orbit and attitude determination for scientific applications.
