It won’t make headlines. There’s no launch date, no countdown clock, no fanfare. But the next time a weather satellite delivers a life-saving forecast, a GPS signal guides a soldier through hostile terrain, or a sprawling antenna network demands precise monitoring and control—something invisible is making it all possible. The same is true when engineers certify a human-rated spacecraft for flight, when a rocket lifts astronauts off the launch pad, or when mission controllers process telemetry from a crewed spacecraft hurtling through orbit. Behind every one of those critical moments, quietly and reliably, is the same proven system.
It’s called OS/COMET®.
For more than 35 years, Peraton’s OS/COMET has been the quiet backbone of some of humanity’s most ambitious missions in space. Born in an era when the space shuttle was still flying and the internet was barely a whisper, OS/COMET, was built to do one thing exceptionally well: keep spacecraft talking to the people who need to hear from them.
Today, it that for multiple satellites, hosted payloads, and ground assets worldwide.
From NOAA’s GOES weather satellites—critical national assets in space that provide essential observations to users—to the U.S. Space Force’s GPS constellation that underpins modern navigation and warfighting operations, OS/COMET executes the workflows that operators depend on around the clock. It monitors telemetry in real time, executes command sequences with precision, and triggers automated responses the moment something unexpected happens—all while keeping a human in the loop when it matters most.
In April 2026, when NASA’s Orion spacecraft, Integrity, carried astronauts farther from Earth than any human has traveled than they ever have been before, it needed a trusted commercial solution they it could trust, OS/COMET® was part of the answer. The system that has quietly served civil, defense, and commercial space for decades was there again, doing what it has always done- invisibly, reliably, without fail.
The true strength of OS/COMET lies not only in its longevity, but in its ability to adapt. In an industry where yesterday’s cutting-edge becomes tomorrow’s legacy burden, OS/COMET has evolved continuously and without compromise. It runs on premises in hardened government facilities, in virtualized environments, and in the cloud. It is scaled from a single spacecraft to multiple space vehicles. It meets the most rigorous security standards—because the missions it supports demand nothing less.
This is not a platform that has survived 35 years by standing still. OS|Comet has evolved alongside the missions it serves—adapting to new architectures, new threats, and new frontiers while maintaining the reliability that operators have staked their missions on for decades.
And yet, for all its reach, OS/COMET has largely operated in obscurity – a trusted workhorse known deeply by the users and organizations who rely on it daily but underrecognized in the broader space community. That’s changing.
The message to the space community is simple: the most proven command-and-control platform in the industry isn’t just keeping pace with the future—it’s ready for it. Cislunar operations, large-scale constellations, next-generation defense architectures—OS/COMET is built for what’s next.
