About SET

Space Environment Technologies (SET) is a global, visionary leader providing space weather mitigation instrumentation and cloud-based data applications to government agencies, academia, and the international commercial aerospace industry. SET and its partners have built an ecosystem of products and services that provides leading-edge space physics models, innovative instruments, and expansive operational data feeds found nowhere else in the world. Combined, these capabilities reduce adverse effects of space weather upon our planet, upon humans, and upon our technology.


Space Environment Technologies (SET) is a global, visionary 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, Maine, South Carolina, Texas, Utah, and West Virginia.

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. In 2021 SET became a S-corp.

When first organized in 2001, SET operated as a single organizational unit and a founding company in the arena of commercial space weather. It signed a Cooperative Research and Development Agreement (CRADA) with NOAA Space Environment Laboratory for producing operational solar irradiances. In addition, from its inception, SET has participated as an active member of the U.S. Technical Advisory Group for Space Systems under the International Standards Organization (ISO) Technical Committee 20 (TC20) Subcommittee 14 (SC14).

In 2004, SET extended its ties to academia as SET’s Chief Scientist, Dr. Tobiska, began, and continues, teaching the Space Environment and Spacecraft Interactions first year graduate course in the University of Southern California’s Department of Astronautical Engineering.

In 2005 SET formed its Space Weather Division (SWD) along with a Research Associates (RA) division for independent researchers affiliated with SET.

In 2005, SET formed a strategic partnership with Exploration Physics, Inc. (EXPI) to produce joint commercial space weather products.

In 2006 a research group from the University of Southern California led by Prof. D. Shemansky joined SET to form its Planetary and Space Sciences Division (PSSD).

In 2006, SET acquired Space Infrastructure, Inc. and merged it into SET’s Infrastructure and Standards Division (ISD). SET continues to be an Executive Board member of the derivative Space Infrastructure Foundation (SIF).

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 order to collaborate with Prof. R. Schunk for the commercialization of the USU GAIM ionosphere model.

In 2010, as an active commercial space weather industry member, SET joined with other companies to form the the American Commercial Space Weather Association (ACSWA). SET is an Executive Committee member in that organization.

In 2019, SET joined the University of Colorado Boulder’s Space Weather Technology, Research and Education Center (SWx-TREC) international 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 in upper atmosphere physics. In addition, SET lends its experience in space systems and space environment standards to the community by participating on the AIAA Standards Steering Committee.

In 2021 SET and the Republic of Korea Space Weather Center signed an international MOU to provide information related to the radiation environment at aircraft altitudes related to human tissue exposure.

In 2022 SET and World View Enterprises signed an MOU to provide instrumentation related to the measurement of radiation at stratospheric balloon altitudes related to human tissue exposure.


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 “gold standard” GAIM model for position, navigation, and timing solutions.

Through his career at NOAA SEL, UC Berkley SSL, JPL, Northrop Grumman, Utah State University SWC, and SET, he has been a Principal Investigator for multiple agencies, leading development on operational systems including USAF HASDM atmosphere density specification 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 year 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 1100 global flights with instruments and models built by SET. Its data extends from the surface of the Earth through suborbital space on World View, Virgin Galactic, and Blue Origin vehicles as well as to LEO orbital space on the ISS and 3 cubesats. The ARMAS program has established the global benchmark for the aviation radiation environment.

Dr. Tobiska has 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. On behalf of the commercial space weather community he has provided testimony to Congress that led to the creation of the PROSWIFT Act.

In 2021, he was selected to represent U.S. industry on the Space Weather Advisory Group (SWAG). SWAG was established by the PROSWIFT Act as a federal advisory group and in September 2021 NOAA announced the appointment of 15 non-government members to the SWAG. The members were chosen to provide a range of views that represent the span of the space weather community and end-user sectors.

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.
