Kepler Communications highlights the Hosted Payload offering, a mission-enabling service built on the operational optical data relay network that provides third-party payload developers accelerated access to orbit, real-time connectivity and broad mission flexibility. The Hosted Payload service provides Kepler’s existing constellation infrastructure to support spacecraft, scientific instruments and communication sensors without the need to build and operate dedicated satellites, providing an efficient alternative for space missions across commercial, research and government domains. Kepler Communications has been developing an optical communication backbone known as the Kepler Network, designed to support real-time connectivity, on-orbit compute and hosted payload operations for space users. With the optical relay constellation technology and on-orbit processing capabilities, hosted payloads benefit from near-continuous connectivity, low latency and global coverage.

Kepler’s Hosted Payload service is created to enable payload developers including government agencies, commercial technology providers, Earth observation missions and scientific researchers to integrate their instruments onto Kepler’s operational satellites. Hosted payload partners can utilize Kepler’s existing optical network infrastructure to accelerate mission timelines, reduce cost and access continuous communications coverage. By hosting payloads on the network, Kepler significantly shortens the time it takes for payloads to reach orbit and begin operations. Payloads integrated into the service gain access to global connectivity and data relay services already proven in orbit rather than building out standalone ground and space infrastructure.

The Hosted Payload service is designed with payload flexibility in mind, offering modular accommodation for various classes of hosted instruments. Customers can integrate payloads up to approximately 120 kg in mass, with payload accommodations designed to support both external and internal configurations. Hosted payload accommodations include standard physical interfaces and thermal, power and data interfaces compatible with Kepler’s spacecraft platforms. The service integrates payload requirements, accommodation analysis and testing within the hosted satellite assembly process, ensuring that hosted systems function correctly within the operational environment. Payload operators benefit from a seamless integration experience backed by Kepler’s on-orbit network operations. Hosted payloads operating on Kepler’s network are connected to a constellation of optical relay satellites that deliver end-to-end, high-capacity data connectivity with latency typically below 750 ms. This real-time communication capability is supported through optical links and integrated ground segments, enabling near-instant data transfer between space, aircraft and terrestrial assets. With daily data capacity exceeding 20 TB per hosted payload, users can stream high volumes of data from orbit, supporting applications such as real-time Earth observation data delivery, live scientific telemetry, command-and-control operations and advanced sensing missions.

Hosted payloads also benefit from Kepler’s on-orbit compute capabilities, which are integrated into the host satellites. These capabilities allow payloads to perform edge processing and data pre-processing directly in space without needing to wait for ground downlink, improving mission responsiveness and reducing latency for data-intensive applications. This capability supports advanced mission concepts including rapid Earth observation processing, distributed sensor networks and near-real-time command execution, enabling hosted payload customers to focus on payload performance while Kepler’s infrastructure handles data routing, storage and connectivity. Kepler’s Hosted Payload service helps customers expedite their mission development cycles by integrating payloads onto existing infrastructure rather than commissioning dedicated spacecraft. Payload developers can provide Kepler’s planned constellation expansion and scheduled launch campaigns to rapidly deploy their instruments, broadening opportunities for early demonstration, operational validation or commercial deployment.

The company encourages interested organizations to submit expressions of interest detailing payload specifications, data requirements, mission concepts and integration needs. By participating in the hosted payload program, customers can gain early access to a network-based communications backbone that simplifies mission communications and accelerates time to mission operations. Kepler’s Hosted Payload offering is designed to support a wide range of mission types, enabling third-party sensors and instruments to benefit from the company’s established connectivity infrastructure. By providing hosted payloads, organizations can reduce upfront investment in spacecraft design and testing and instead harness the Kepler Network’s communications and compute layers to focus on mission-specific technology performance.

About Kepler Communications

Kepler Communications is a satellite operator and space communications company providing data-relay and connectivity services for satellites, spacecraft and space-based sensors. Headquartered in Toronto, Ontario, Canada, Kepler designs, builds and operates their own low Earth orbit (LEO) satellite constellation to enable reliable, near-real-time data transfer between space assets and ground networks. The company’s services are focused on supporting missions that require frequent contact, low-latency data delivery and global coverage, including Earth observation, scientific missions and technology-demonstration spacecraft. Kepler’s network is built around store-and-forward and relay-based communications, allowing satellites to downlink data more often than traditional ground-station-only approaches. By combining space-based relay infrastructure with integrated ground services and mission interfaces, Kepler enables operators to reduce data latency, increase contact opportunities and simplify mission operations without deploying dedicated global ground networks.
