Tech7 wins defence satellite software testbed award

Tech7 has received a Direct-to-Phase-II Small Business Innovation Research award to develop a software testbed for applications intended for the Space Development Agency’s proliferated low-Earth-orbit satellite programmes. Facilitated by SpaceWERX, the Direct-to-Phase-II award funds development of the Proliferated LEO Agile Testbed Environment, known as PLATE. The company expects work to begin in October 2026. Neither the value nor the contract number was disclosed in its announcement.

PLATE is planned initially as an unclassified, Amazon Web Services-based prototype. Its purpose is to let developers mature, test and demonstrate applications that could later be considered for one or more SDA satellite tranches. Tech7 envisages a multi-security-level system as a future Phase III transition, but the current award is for the initial unclassified testbed; no Phase III award or accredited operational deployment has been announced.

SDA’s Proliferated Warfighter Space Architecture uses multiple spacecraft in low Earth orbit rather than relying solely on a small number of large, specialised platforms. That approach produces distributed streams of information which must be received, interpreted and shared across different applications and ground systems. PLATE is intended to provide a separate environment for testing how candidate software handles representative data and exchanges messages across interfaces before decisions are made about mission-system integration.

An application can perform correctly when tested against a small collection of static files yet behave differently when many sensors produce data at varying rates. Processing queues, timing dependencies, missing records and network delays all affect how information reaches later stages of a system. Engineers can use a prototype environment to introduce controlled changes in input rate, delay and failure conditions, then measure application responses. Tech7 has not published PLATE’s test catalogue, expected data volumes or acceptance thresholds, so its final validation envelope remains unspecified.

Interoperability presents a parallel engineering challenge. Software supplied by different vendors may use incompatible message formats, assumptions about timestamps or representations of location and identity. A shared test interface can expose differences in message structure or data handling before an application is proposed for connection to mission systems. Tech7 says PLATE should allow applications from large contractors, smaller firms and non-traditional suppliers to be evaluated, but the award does not list participating application developers or future procurement winners.

An initially unclassified AWS environment permits software experiments with permitted datasets while excluding classified data and functions not approved for that environment. Security-sensitive information cannot simply be introduced into an unclassified system because its software runs successfully. A future move to multiple security levels would require a different set of controls for access, information separation, accreditation and operational support. Those later controls are part of Tech7’s intended transition route, not deliverables already demonstrated under this award.

Tech7 identifies its existing work supporting the Space Systems Command missile-warning enterprise, including the Overhead Persistent Infrared Tools, Applications and Processing Lab and the OPIR Modeling and Simulation Analysis Center, as experience it can draw upon. That background describes the experience Tech7 plans to draw upon. It does not establish that PLATE is already part of those missile-warning programmes or that SDA has selected any existing Tech7 application for operational use.

Direct-to-Phase-II SBIR awards support accelerated prototype development without the standard earlier Phase I sequence. That procurement route can finance engineering and demonstration activities where the technical proposition is sufficiently mature to move into a more substantial test programme. The funded deliverable is prototype development rather than a recurring operational service. Tech7 has not disclosed the contract value, specific acceptance milestones or a timetable for any potential later transition decision.

SDA’s small-business and prototyping activity provides a route for evaluating new technologies separately from existing operational spacecraft contracts. PLATE would address the software-test portion of that wider effort by providing a place where applications can be evaluated against a controlled environment. Whether it subsequently becomes a standard integration pipeline will depend on completed development work, government assessment and any later funded order. The current disclosure does not identify how that future procurement would be competed or allocated.

PLATE’s immediate industrial deliverable is a software test and evaluation prototype, rather than additional satellites or a production commitment. Tech7 must turn its description of a reusable environment into working software, integration interfaces and demonstrable tests before an operational customer can decide how widely to use it. Tech7 expects to start work in October; the programme’s financial scale, demonstrated test results and prospects for Phase III deployment have not been announced.
