In Sherbrooke, a city known for its burgeoning technology scene, NGC Aerospace has emerged as a pivotal player in global space exploration.

Established in 2001 by visionary Jean de Lafontaine, this innovative company specializes in autonomous satellite software, positioning Canada as a key contributor in the aerospace industry. Their latest triumph? A vital role in the European Space Agency’s (ESA) groundbreaking PROBA-3 satellite mission, designed to unlock the secrets of the Sun's corona.

From Humble Beginnings to Industry Leader

Jean de Lafontaine's journey with NGC Aerospace illustrates a remarkable evolution from a small startup to a globally recognized enterprise. "Our software reduces operational costs by automating satellite functions," he stated in a recent interview. Traditionally, extensive ground teams were necessary for spacecraft operations, but NGC’s advanced onboard systems have transformed this model, allowing satellites to operate with unprecedented precision and autonomy. This capability is essential for missions like PROBA-3, where exact positioning is vital.

Situated within Sherbrooke’s technology park, NGC Aerospace has evolved into a powerhouse of engineering talent, much of which is drawn from de Lafontaine's own academic connections at the Université de Sherbrooke. This unique advantage has helped cultivate a team of dedicated professionals, with many of the company’s early hires still contributing after 20 years of service.

Pioneering Solar Research with PROBA-3

The PROBA-3 mission, which launched on December 5, represents a significant leap forward in solar research. By utilizing a dual-satellite design—a coronagraph and an occulter—scientists can create artificial eclipses occurring every 20 hours, facilitating long-term observations of the solar corona. This crucial layer of the Sun's atmosphere is notorious for producing solar flares and other phenomena that can disrupt technology on Earth, including communication systems and power grids.

"Solar flares caused Quebec’s infamous 1989 blackout," de Lafontaine remarked, emphasizing the importance of understanding solar activity for predicting similar events. With NGC Aerospace’s sophisticated software in control, the two satellites can maintain millidegree orientation and millimeter positioning, delivering an unparalleled level of precision for solar observation. The eclipses generated can last up to six hours, thus providing scientists with a rare opportunity to study the significant role the corona plays in stellar storms.

A Technological Symphony in Space

Beyond scientific advancement, PROBA-3 pioneers a new era of technological achievements in space exploration. This mission stands as a first-of-its-kind demonstration of high-precision formation flying. The two satellites must maintain an exact separation of 150 meters, staying aligned with millimeter accuracy. They continuously exchange data to ensure their formation remains stable. Any deviation from this alignment could expose the coronagraph to direct sunlight, jeopardizing data integrity and the entire mission.

As NGC Aerospace continues to push the boundaries of what's possible in astronautics, their work on the PROBA-3 mission not only enhances our understanding of solar dynamics but also showcases Canada's growing expertise on the international aerospace stage. The future of space exploration indeed looks bright, with innovators like NGC leading the charge.
