At COMSPOC, we believe there are eight essential attributes to a truly comprehensive SSA operations center.

The ability to support operations in any orbit is one of these essential attributes.

In addition to fusing data from any type of sensor, SSASuite harmonizes observation data across LEO, MEO, GEO, and cislunar space to create a comprehensive view of the space environment from Earth to the Moon.

NHK, the Japan Broadcasting Corporation, goes inside COMSPOC’s operations center for an in-depth look at SSA, and the rapid advance of Chinese space capabilities. As part of a feature on the importance of commercial technologies in the space sector, this piece explores how COMSPOC uses its own commercially available SSASuite software platform to track objects in orbit, analyze satellite behavior, and support real-world decision-making. COMSPOC CEO Paul Graziani discusses the growing importance of actionable space domain awareness to support safety, security, and informed decision-making.

Ars Technica recently featured analysis by @COMSPOC_OPS in its coverage of growing activity in geosynchronous orbit.

The article, “Three’s a party: US, China, and now Russia are on the prowl in GEO,” by @StephenClark1, examines how U.S., Chinese and Russian satellites are maneuvering in GEO as reconnaissance and surveillance activity increases.

Orbit solutions produced using COMSPOC’s SSASuite helped show the activity between USA-325 and Russia’s Kosmos 2589, including two close approaches per day and a closest approach of about 13 kilometers on May 1. The ability to quickly detect and characterize such refined maneuvering is one of the essential elements that separates SDA from ordinary SSA.

SSASuite fuses data from all available sensors to take advantage of the strengths of each and, likewise, to ameliorate their weaknesses.

Thanks to @MichaelDWall at @SPACEdotcom for highlighting the @COMSPOC_OPS team’s analysis of a recent Russian satellite multi-object proximity event. The satellites, known as COSMOS 2581 and COSMOS 2583, got within just 10 feet (3 meters) of each other on April 28. As the ops team noted, "This wasn't a coincidental pass — COSMOS 2583 performed several fine maneuvers to maintain this tight configuration."

It was a busy week for the COMSPOC team. Jim Cooper, government relations manager, took part in C4ISR Global 2026 in London, where he joined the Industry Innovator Panel on accelerating intelligence, situational awareness, and decision advantage for the future force. Meanwhile, Chief Scientist Dan Oltrogge represented COMSPOC at the Plenary and Working Groups Meetings of ISO TC 20/SC 14 Space Systems and Operations in New Delhi.

Pakistan's PRSC-EO3: an unusual orbit for an optical satellite

Radar tracking via @LeoLabs. Processed via COMSPOC SSA.

PRSC-EO3 (visualized in cyan) launched April 25, 2026 on a Long March 6. It's an optical imager — but its orbit is curious.

Most optical LEO satellites use sun-synchronous orbits (~97-105° inclination), which provide consistent lighting for imaging. PRSC-EO3 is in a 38° inclined orbit instead. This sacrifices global coverage and consistent lighting, but increases revisit rates over a specific latitude band: 20-40°N. That's India, Kashmir, and Pakistan.

Now consider PRSC-S1 (visualized in pink), Pakistan's SAR satellite launched July 2025, sitting in a 41° orbit. Similar inclination, similar altitude — but their RAANs are ~175° out of phase. When one passes over South Asia in daylight, the other passes in darkness.

SAR works day and night. Optical needs sunlight. The geometry appears to allow complementary coverage.

We ran the access analysis [Image 1]. The SAR sensor (unconstrained) and optical sensor (daytime-constrained) together provide repeatable revisit across day and night. The gaps left by one are filled by the other.

Then there's PRSC-HS1 — a hyperspectral satellite in SSO [Image 2], capable of detecting camouflage and identifying materials from orbit.

Optical shows you the picture. SAR shows you the picture at night and through weather. Hyperspectral tells you what you're looking at.

Five remote sensing satellites in 16 months [Image 2]. All launched by China. All with orbits favoring South Asian coverage. The stated missions are civilian. The orbital architecture appears consistent with a multi-modal ISR constellation.

The @COMSPOC_OPS team is featured throughout @IntegrityISR’s latest Integrity Flash issue for their analysis of recent activity in orbit, including USA 325’s activity near Cosmos 2589 in GEO, and rendezvous and proximity operations between Cosmos 2581 and 2583, where the two objects were as near as 3m from one another.

As the article notes, since publicly available orbit data had gone stale, author Greg Gillinger turned to the COMSPOC ops team for help, and they “did not disappoint!” 😊

Cosmos 2589 has completed its transition into geosynchronous orbit after a multi-month maneuver.

USA 325 moved into proximity, with repeated close approaches and distances tightening to as little as 13 km under favorable conditions.

👀USA 325 keeps an eye on COSMOS 2589 as it settles into GEO

COSMOS 2589 🇷🇺 (launched last June) spent the past few weeks circularizing its orbit before parking at ~98°E. USA 325 🇺🇸 (GSSAP-6) was watching the whole time.

Things got interesting around April 19th when COSMOS 2589 actually drifted past USA 325 mid-maneuver. USA 325 repositioned, and by late April both were sitting at the same longitude.

From there, observation passes came twice a day due to their different inclinations. Closest was ~13 km on 1 May, with sun angles lining up nicely for a good look.

3D visualization attached — you can really see how COSMOS 2589 tightened its orbit while USA 325 adjusted to stay in position.

This is what GSSAP does: when something new shows up in GEO, they're there to take a look.

🛰️Russian satellites multi-object proximity event in LEO

Radar tracking data via @LeoLabs_Space, processed through COMSPOC SSA Suite.

This week we observed a complex proximity event involving Russian satellites: COSMOS 2581, 2582, 2583, and Object F (a subsatellite released by 2583).

The highlight: COSMOS 2581 and 2583 achieved a closest approach of ~3 meters on 28 April at UTC, with near-zero relative velocity. This wasn't a coincidental pass — COSMOS 2583 performed several fine maneuvers to maintain this tight configuration.

Meanwhile, COSMOS 2582 trailed the formation at sub-100 km range, while Object F passed within 15 km of 2582 and within 10 km of 2581 — neither maneuvered.

For context: in late 2025 to now, we tracked these same COSMOS satellites performing 3-object RPO. These satellites launched 5 February 2025. Whatever Russia is testing, it's sophisticated.
