Space Flight Laboratory (SFL) Announces Successful Launch of 12 Satellites on SpaceX Ride-Sharing Mission @SFL_SmallerSats

TORONTO, Ontario, Canada, 25 January 2021 – Space Flight Laboratory (SFL), a developer of complete microspace missions, today announced the launch and successful deployment of 12 satellites on January 24, 2021. The SpaceX Falcon 9 ride-sharing mission carried three different SFL-designed microspace platforms into orbit for three separate commercial constellations.

The January 24 launch included:

• Three formation-flying, radio frequency geolocating microsatellites built upon SFL’s 30-kg DEFIANT platform for HawkEye 360 Inc. of Herndon, VA.
• One next-generation greenhouse gas monitoring microsatellite, known as GHGSat-C2 or “Hugo”, built by SFL on its 15-kg NEMO platform for GHGSat Inc. of Montreal, Canada.
• Eight commercial communications CubeSats developed using the SFL 6U-XL SPARTAN design.

This week’s deployment of the DEFIANT microsatellites also marked the third entirely new microspace platform developed by SFL to reach orbit in just the past five months. SFL’s SPARTAN bus was introduced for the first time on September 28, 2020, with the launch of two communications CubeSats. And SFL’s NAUTILUS microsatellite platform made its debut on September 2, 2020, with the launch of the NEMO-HD Earth observation mission for Slovenia.

“These launches demonstrate SFL’s unmatched ability to innovate and deliver quality at any size on short schedules,” said SFL Director, Dr. Robert E. Zee. “SFL is a unique microspace provider that offers a complete suite of nano-, micro- and small satellites – including high-performance, low-cost CubeSats – that satisfy the needs of a broad range of mission types from 3 to 500 kilograms.”

Dating from 1998, SFL’s heritage of on-orbit successes includes 65 distinct missions related to Earth observation, atmospheric monitoring, ship tracking, communication, radio frequency (RF) geolocation, technology demonstration, space astronomy, solar physics, space plasma, and other scientific research.

GHGSat Inc. awarded SFL the development contract for GHGSat-C1 (“Iris”) and C2 (“Hugo”) after SFL built and launched the pathfinding GHGSat-D (“Claire”) atmospheric monitoring microsatellite in 2016. Successful detection of ground-based methane emissions from space is due in part to the precise attitude control and target tracking capability of the SFL NEMO bus. In Nov 2020, SFL was awarded a contract by GHGSat to build an additional three microsatellites for its commercial greenhouse gas monitoring constellation.

For HawkEye 360 Inc., SFL built platforms and integrated the HawkEye 360 Pathfinder cluster which was launched into low-Earth orbit in December 2018. Based on this success, SFL’s satellite technology was selected for the HawkEye 360 Constellation mission due to the importance of formation flying by multiple satellites for successful RF geolocation and analysis used in maritime situational awareness, national security operations, and many other applications. For the 2021 launch, the larger DEFIANT bus was developed by SFL to accommodate advanced onboard technologies.

In its 22-year history, SFL has developed CubeSats, nanosatellites, and microsatellites that have achieved more than 135 cumulative years of operation in orbit. These microspace missions have included SFL’s trusted attitude control and, in some cases, formation-flying capabilities. Other core SFL-developed components include modular (scalable) power systems, onboard radios, flight computers, and control software.

About Space Flight Laboratory (SFL) (www.utias-sfl.net)

SFL generates bigger returns from smaller, lower cost satellites. Small satellites built by SFL consistently push the performance envelope and disrupt the traditional cost paradigm. Satellites are built with advanced power systems, stringent attitude control and high-volume data capacity that are striking relative to the budget. SFL arranges launches globally and maintains a mission control center accessing ground stations worldwide. The pioneering and barrier-breaking work of SFL is a key enabler to tomorrow’s cost aggressive satellite constellations. (www.utias-sfl.net)
