GSAT™, rooted in the legacy of Robert Briskman, is dedicated to ensuring the openness and safety of space by excelling in Space Domain Awareness (SDA), preventing satellite collisions, defending against hostile threats, and elevating space operations through innovative data harvesting, data engineering and AI solutions for a valuable, virgin data set for high dollar assets and resources. Beyond mere physical asset protection, the subsystem provides improved space awareness to the GEO operators backed by decades of projects and operational efforts by Mr. Robert Briskman, co-founder of Sirius XM Radio, through the use of our globally recognized patent protected systems validated and verified by the National Science Foundation (NSF) and the Aerospace Corporation. GuardianSat™ is also developing its patented autonomous onboard anti-satellite weapon countermeasure system to neutralize both ground, air and space based hostile attacks using its propriety technology. This technology will counter the increase of anti-satellite (ASAT) weapons development and testing that has proceeded mostly unanswered.
