Geost

What Geost does

Geost is a Tucson, Arizona-based defense technology company that designs and manufactures electro-optical and infrared (EO/IR) sensor payloads for space-based national security missions. Following its August 2025 acquisition by Rocket Lab USA for $275-325 million, the company now operates as Rocket Lab Optical Systems, integrating its EO/IR sensor payloads into Rocket Lab's vertically integrated space systems portfolio spanning bus manufacturing, launch, and constellation operations.

The company's product portfolio centers on three payload families: Heimdall (a wide-field-of-view EO/IR payload designed for the U.S. Space Development Agency's Proliferated Warfighter Space Architecture and missile warning/tracking missions), Phoenix (an intelligence, surveillance and reconnaissance payload), and Starlite (a space domain awareness and space-protection payload). Reported on-orbit performance is 100% mission success across deployed hardware. Core technology spans optics, focal-plane arrays, hosted-payload integration, and onboard processing, with the company's hosted-payload model designed for low-cost, mass-producible deployment across proliferated LEO, GEO, and emerging cislunar orbits.

Geost's business model is anchored in long-cycle U.S. government defense procurement. Revenue is generated through multi-year fixed-price development contracts and prototype-to-production transitions — most visibly a $90 million U.S. Space Force award covering two GEO-orbit satellites carrying the Heimdall payload. The customer base is effectively monolithic: the U.S. Department of Defense, primarily the U.S. Space Force and the Space Development Agency. The company's pre-acquisition ownership by private equity sponsor ATL Partners indicates institutional scale, though standalone financials are not publicly disclosed.

Core offering

Geost designs, engineers, and manufactures custom electro-optical and infrared (EO/IR) sensor payloads and optical assemblies for U.S. national security space missions. Its product portfolio includes the Heimdall space domain awareness payload, Starlite space protection payload, and Phoenix ISR payload, along with SWIR/MWIR/LWIR infrared sensors and high-resolution electro-optical imaging systems integrated into satellite platforms. Following its August 2025 acquisition by Rocket Lab, Geost operates as Rocket Lab Optical Systems, delivering sensing solutions for missile defense, space domain awareness, and space protection across LEO, GEO, and cislunar orbits.

Product overview

Geost, acquired by Rocket Lab in August 2025 and rebranded as Rocket Lab Optical Systems, provides a portfolio of custom electro-optical and infrared (EO/IR) sensor payloads for U.S. national security and space domain awareness missions. The product portfolio includes three named payload systems: Heimdall (space domain awareness), Starlite (space protection), and Phoenix (ISR), complemented by core sensor technologies spanning SWIR/MWIR/LWIR infrared sensors and high-resolution electro-optical imaging systems. These payloads integrate with Rocket Lab's Lightning bus platform and support missile defense, space domain awareness, and space protection mission areas across all orbital domains.

Partnerships

Two partnerships are on record, tiered core.

• Rocket LabcoreStrategic or Co-development Partner · 12 August 2025Geost was acquired by Rocket Lab in August 2025 for $275-$325 million. The acquisition was structured as $125 million in cash and $150 million in Rocket Lab stock. Geost is now integrated as Rocket Lab Optical Systems, delivering satellite payloads purpose-built for U.S. national security and intelligence missions, building on over 20 years of electro-optical and infrared systems innovation.
• Optical Support InccoreStrategic or Co-development PartnerOptical Support Inc (OSI) had an established working relationship with Geost prior to being acquired by Rocket Lab. OSI was acquired separately by Rocket Lab and both Geost and OSI are now part of Rocket Lab Optical Systems, with OSI adding 22,000 square feet of advanced machining, testing and integration facilities.
