Tiami Networks Advances PolySpace Toward 2027 In-Orbit 5G ISAC Demonstration

Planned flight series begins with a July 2027 passive sensing mission aboard a Blackwing Space nanosatellite and advances toward full 5G NTN ISAC

SACRAMENTO, CA, UNITED STATES, September 16, 2026 /EINPresswire.com/ — Tiami Networks, a developer of integrated sensing and communications technologies, today announced plans for a series of in-orbit demonstrations of PolySpace, its space-based 5G Integrated Sensing and Communications (ISAC) initiative, beginning with a passive-sensing mission targeted for July 2027.

The first mission is intended to be the world’s first in-orbit 5G ISAC demonstration, using communications transmissions as signals of opportunity for passive sensing. Follow-on missions are planned to expand PolySpace toward a full 5G NTN implementation, integrating Tiami’s ISAC technology with a 5G NTN gNodeB and more advanced communications and sensing capabilities.

PolySpace is intended to explore how emerging 5G and 6G non-terrestrial networks can support both communications and sensing. Tiami’s long-term vision is to transform broadband 4G and 5G satellites, including large commercial megaconstellations, into software-defined radar sensors by adding sensing capabilities to communications infrastructure. The concept would extend Tiami’s terrestrial ISAC architecture into space, enabling satellite networks to provide sensing functions without requiring separate, single-purpose sensing systems.

“PolySpace represents the next evolution of Tiami’s vision for integrated sensing and communications,” said Amitav Mukherjee, Founder and CEO of Tiami Networks. “The communications infrastructure being deployed across low Earth orbit creates an opportunity to build sensing directly into future non-terrestrial networks. By bringing together the right physical-layer, platform, and integration capabilities, we can move that vision from a terrestrial demonstration environment toward validation in orbit.”

Under the proposed architecture, Tiami would provide the ISAC sensing algorithms, artificial intelligence and associated software, including its PolyRAN OCUDU application and PolySense API. Tiami’s technology is designed to extract radar sensing information from communications waveforms using delay, Doppler and other signal characteristics while applying AI to support moving target classification.

Tiami is targeting a July 2027 launch of the PolySpace payload aboard a Blackwing Space nanosatellite through a commercial rideshare mission to low Earth orbit. Blackwing Space will provide a dedicated Kestrel 3U XL platform, payload integration, and launch access, with the program progressing through mission design, payload integration, and environmental testing ahead of flight. Once in orbit, the first PolySpace mission is planned to demonstrate passive ISAC using 5G communications transmissions as signals of opportunity from the space-based platform in the S-band spectrum. Active and cooperative sensing architectures are planned for later PolySpace missions as the platform evolves toward a full 5G NTN ISAC implementation.

“PolySpace is exactly the kind of mission our nanosatellite platforms are built for,” said Paul Anderson, Founder and CEO of Blackwing Space. “Rapid payload integration and flexible access to orbit mean we can help Tiami move their ISAC technology from terrestrial validation to an in-orbit demonstration, and start exploring what that enables for the next generation of satellite networks.”

Potential applications include aviation safety, awareness beyond the coverage of terrestrial radar, space-domain awareness, object monitoring and future satellite detect-and-avoid capabilities. The initial mission would be a technology demonstration intended to validate elements of the architecture rather than deploy an operational sensing service.

PolySpace builds on Tiami’s previous work applying ISAC to terrestrial and space-to-ground communications signals. In February 2026, Tiami conducted a space-to-ground ISAC demonstration at Playas Research and Training Center in New Mexico, using a Starlink Direct-to-Cell 4G LTE transmission to support helicopter detection. The next technical challenge is to conduct sensing aboard a space-based platform using ground-to-space signals.

The development roadmap for the initial mission progresses from system specifications and interface definitions through sensing-algorithm development, payload construction, environmental testing and launch. Following the July 2027 demonstration, planned flight iterations will expand the architecture toward full 5G NTN integrated communications and sensing.

“This is about more than launching one payload,” Mukherjee shared. “It is about demonstrating a pathway for future communications satellites to become dual-use sensing platforms. As 5G NTN expands and 6G introduces sensing more directly into network architectures, PolySpace can help establish how those networks provide both connectivity and greater awareness.”

Additional mission details will be announced as partner roles, technical architecture, commercial agreements and the flight schedule are finalized.
