SAM-300 / PROPOSED HARDWARE ADMISSION ARCHITECTURE
Move the trust decision upstream.
Check the physics before software relies on the measurement.
Sovereign Edge Systems, Inc. is developing SAM-300 to bring hardware-controlled signal admission to positioning, navigation, and timing. The architecture combines orbital RF consistency checks with a hardware boundary that controls which measurements become available to downstream systems.
In development: an RF-only GPS implementation using an FPGA after digitization and before navigation or fusion. Planned delivery options include embedded licensing and SES hardware modules.
Current maturity: technology readiness level 2. Preliminary software analysis has compared predicted Doppler with recorded GPS data; RF spoofing detection and hardware-enforced withholding remain to be demonstrated.
One admission boundary. Three design functions.
01 / Physical-consistency checks
Compare selected orbital RF observables with predicted behavior and a defined error budget.
02 / Hardware-enforced withholding
Apply FPGA admission criteria to withhold measurements that fail the checks before they become available downstream.
03 / Host-isolated release
Release qualified measurements through a controlled interface, keeping upstream admission separate from host control.
A foundation for trust at the edge.
Our initial focus is defense A-PNT integrators and GNSS receiver providers. We are developing hardware-controlled measurement admission for systems that depend on reliable external signals, with critical-infrastructure timing as an adjacent opportunity.
We are developing SAM-300 for two production delivery paths: licensing the implementation into customer hardware and supplying SES hardware modules through manufacturing partners. Both paths begin with technical evaluation and integration around customer requirements.
