Orbit Keeper 01
A reusable orbital platform designed for long-duration operations in Low Earth Orbit, providing hosted payload and orbital computing capabilities without requiring customers to build and operate an entire spacecraft.
What is Orbit Keeper 01 ?
Orbit Keeper 01 is a commercial orbital service platform designed to make access to space simpler. Instead of requiring every organization to build, launch, and operate an entire spacecraft, OK-01 provides a shared platform that customers can use for their own missions in orbit.
Customers can bring compatible hardware and have it hosted on Orbit Keeper 01, run software and workloads on dedicated orbital computing infrastructure, or access capabilities operated by Graviron. The spacecraft provides the common infrastructure needed to operate these missions — including power, communications, thermal management, attitude control, data handling, and on-orbit operations.
One spacecraft. Multiple customers. Multiple missions.
The idea is simple: customers shouldn't always need an entire spacecraft to use space. A company developing a sensor, a university testing an experiment, or a technology company validating a new system may only need access to a specific capability in orbit. With OK-01, they can use the infrastructure already operating in space instead of building an entire satellite around their mission.
One Vehicle. Many Missions.
Traditional spacecraft are typically designed for a single mission and are retired once that mission is complete. Orbit Keeper is designed differently. By performing multiple missions throughout its operational lifetime, a reusable orbital drone can reduce the cost of repeated space operations while providing customers with faster, more flexible access to orbital services. Reusability is increasingly viewed as a key enabler for the future of in-space servicing and a more sustainable orbital economy.
Traditional Spacecraft
|
MISSION-SPECIFIC SPACECRAFT |
A spacecraft is developed around a specific customer, payload, or mission and carries the infrastructure required for that mission. |
|---|---|
|
BUILD THE ENTIRE SPACECRAFT |
Customers may need to develop, integrate, launch, communicate with, and operate an entire spacecraft to accomplish their mission. |
|
DEDICATED INFRASTRUCTURE |
Spacecraft resources are primarily configured around the requirements of a particular mission and customer. |
|
ONE MISSION AT A TIME |
The spacecraft is typically built around a defined mission and payload architecture. |
|
CUSTOMER OWNS THE MISSION STACK |
The customer carries responsibility for a much larger portion of the spacecraft and mission infrastructure. |
|
BUILD FOR ONE MISSION |
A new spacecraft and supporting infrastructure may be required for each new mission. |

SHARED ORBITAL PLATFORM |
One orbital platform is designed to support multiple customers, payloads, workloads, and missions throughout its operational lifetime. |
|---|---|
|
USE THE INFRASTRUCTURE YOU NEED |
Customers can bring compatible hardware, run software on orbital computing infrastructure, or access Graviron-operated capabilities without building an entire spacecraft themselves. |
|
SHARED INFRASTRUCTURE |
Power, communications, thermal management, attitude control, data handling, and other spacecraft resources can be shared across multiple missions and payloads. |
|
MULTIPLE MISSIONS OVER ONE PLATFORM |
OK-01 is designed so different customers can use available orbital capacity throughout the platform's operational lifetime. |
|
GRAVIRON OPERATES THE PLATFORM |
Graviron operates the orbital platform while customers focus on their payload, software, or required orbital capability. |
|
BUILD ONCE. SERVE MANY. |
The same orbital infrastructure is designed to support different customers and use cases over time. |

Multiple Ways to Use Orbit.
Orbit Keeper 01 combines shared spacecraft infrastructure with hosted payloads, dedicated orbital computing, and Graviron-operated capabilities, giving customers multiple ways to access and use space.
HOSTED PAYLOADS
Bring your hardware. We'll handle the spacecraft.
Thousands of satellites currently operate in Earth orbit, and that number continues to grow every year — creating increasing demand for post-launch operations and support.
ORBITAL COMPUTE
Run your workloads in orbit.
Deploy software, algorithms, and computing workloads on dedicated onboard infrastructure — enabling applications such as AI inference, image processing, data filtering, and autonomous decision-making.
RELAY INFRA
Access capabilities already in orbit.
Graviron can operate its own sensors, computing systems, experimental payloads, and other orbital infrastructure — allowing customers to access capabilities without owning the underlying hardware.
One spacecraft. Built around the mission.
Orbit Keeper 01 combines a modular spacecraft bus with shared infrastructure designed to support different payloads, computing workloads, and orbital services throughout its operational lifetime.
Payload Infrastructure
Space for what you need to fly.
Standardized interfaces allow compatible customer and Graviron-owned payloads to operate on the same orbital platform.
Power & Thermal
The resources that keep everything running.
Shared power and thermal systems provide the resources needed to operate hosted payloads and onboard spacecraft systems.
Propulsion & Attitude Control
Move. Maneuver. Maintain the mission.
Propulsion and attitude-control systems support orbital operations and maintain the spacecraft's required orientation and trajectory.
Communication & Data
Connect the spacecraft to the ground.
Shared communications and data infrastructure enables command, telemetry, payload data transfer, and mission operations.
One platform. Three configurations.
Orbit Keeper 01 is designed as a modular orbital platform, with configurations optimized for different mission durations, power requirements, and payload needs.
Vector
Compact LEO Platform
Designed for shorter-duration missions and lower-power hosted payloads.
Horizon
Extended Platform
Designed for longer-duration missions with increased power and payload capacity.
Zenith
High-Capability Platform
Designed for the most demanding OK-01 missions, with maximum endurance, power and payload capability.
From development to orbit.
Orbit Keeper 01 is currently in development, with Graviron progressing from spacecraft architecture and subsystem development toward an orbital demonstration and initial commercial operations.
Mission Timeline
Design. Build. Test.
Developing the spacecraft architecture, interfaces, subsystems, and ground-test capabilities required for orbital operations.
Prove the platform in orbit.
Demonstrate the core capabilities of Orbit Keeper 01 and validate its shared orbital platform architecture in a real operational environment.
Put the platform to work.
Begin commercial orbital services, initially centered around hosted payloads, orbital computing, and Graviron-operated orbital infrastructure.
