About SET


Space Environment Technologies (SET) is a global leader providing space weather mitigation instrumentation and cloud-based data applications to the U.S. government, academia, and the international commercial aerospace industry.

Space Environment Technologies (SET) is headquartered in Pacific Palisades, California with team members in Arizona, California, Colorado, Texas, Utah, and Maine.

SET was organized in 2001 as a sole proprietorship and then converted to a Limited Liability Corporation in 2005 under the laws of the State of California.

When first organized, SET operated as one division in the arena of space weather. In 2005 SET acquired Space Infrastructure to form its Infrastructure and Standards Division (ISD). At the same time, the Space Weather Division (SWD) was formed along with a Research Associates (RA) division for independent researchers affiliated with SET. In 2006 a research group from the University of Southern California led by Prof. D. Shemansky joined SET to form the Planetary and Space Sciences Division (PSSD).

In 2005, SET formed a strategic partnership with EXPI to produce commercial space weather products. In 2009, SET formed a strategic partnership with Utah State University, where Dr. Tobiska additionally took a position as the USU Space Weather Center Director. In 2019, SET joined the University of Colorado Boulder’s Space Weather Technology, Research and Education Center (SWx-TREC) inational center of excellence as an industry partner. In 2020, SET and West Virginia University signed a SET HASDM Database Use Agreement to further scientific research.

SET is an active industry member of the American Commercial Space Weather Association (ACSWA), the U.S. Technical Advisory Group for ISO TC20/SC14 Space Systems, and the AIAA Standards Steering Committee.


Following a decade of work as an instrument scientist with the Galileo spacecraft at NASA’s Jet Propulsion Laboratory (JPL), W. Kent and Susan R. Tobiska formed SET in August 2001. Dr. Tobiska obtained worldwide rights from Northrop Grumman to his research, software, and hardware associated with their SpaceWx division. The new SET acquired the trademark name of SpaceWx. Please visit our News page to explore the advances SET has made since 2001.

Dr. Tobiska has a 4 decade long history in space sciences and space weather. He founded and is the President and Chief Scientist of Space Environment Technologies (SET), which is now the world’s leading commercial provider of space weather. He founded and was President of Q-Up, providing space weather effects on HF radio propagation. He founded and was the Director of the Utah State University Space Weather Center, which commercialized the use of the GAIM model for position, navigation, and timing solutions.

Through his career at NOAA, JPL, Northrop Grumman, Utah State University, and SET, he has been a Principal Investigator for multiple agencies, leading development on operational systems including USAF HASDM atmosphere density and NASA ARMAS radiation monitoring. The former program is now the “gold standard” for atmospheric density and is used to produce the NORAD satellite catalog every few hours. The ISS is moved approximately once a month based on SET’s predicts of solar and geomagnetic drivers to atmospheric density and its effects upon debris object orbits. The latter program, ARMAS, provides the first ever real-time radiation measurements for helping pilots and air traffic organizations manage space weather related radiation hazards. That program now has over 750 global flights with instruments and models built by SET. Its data extends from the surface of the Earth to suborbital space on World View, Virgin Galactic, and Blue Origin vehicles as well as on agency research aircraft and commercial/business aviation jets.

Dr. Tobiska chaired the COSPAR CIRA Task group and the AIAA Atmospheric and Space Environment (ASE) Committee on Standards (CoS) for nearly a decade. He continues to serve as lead U.S. delegate to ISO for the space environment since 2000. He has served on the NRC Decadal Survey for heliophysics and the NASA Heliophysics Division Science Advisory Committee.

Dr. Tobiska has authored/co-authored over 200 peer-review scientific papers as well as 10 books and major technical publications. Dr. Tobiska is a member of AGU, COSPAR, AIAA, AMS, NBAA, ACSWA, and ISO TC20/SC14 U.S. TAG.
