Adversary Electronic Warfare (EW) jamming and coordinate spoofing sever GNSS uplinks and inject malicious time steps. Civil UTC time contains irregular leap-second insertions that cause computer clocks to repeat or freeze seconds, introducing kilometers of navigational error during high-velocity flight and collapsing navigation Kalman filters.

Standardizes on strictly monotonic International Atomic Time (TAI / TT) governed by BIPM paired with 3D velocity vectors, SO(3) attitude quaternions, and a 32-byte SHA-256 integrity seal. Executes deterministic dead-reckoning during GNSS denial, preserves metrology-grade timing, and rejects spoofed packets or bit-flips before they corrupt the flight loop.

Collaborative Combat Aircraft (CCA) and attritable drone swarms (AUTOWARCOM / DRPM-UxS) combine mixed microcontrollers (ARM Cortex-R, LEON4, RISC-V, x86_64). Discrepancies in compiler struct padding, endianness, or floating-point negative zero (-0.0) create divergence in decentralized target state estimation.

Enforces a strictly packed 136-byte binary wire layout with normalized IEEE-754 floats (+0.0 canonicalization) and fixed Little-Endian byte ordering. Swarm nodes communicate peer-to-peer with exact bitwise parity across disparate architectures, enabling deterministic target handovers and decentralized consensus.

Hypersonic vehicles (Mach 5+) experience thermal ionization plasma sheaths that sever RF uplinks, while disparate test range sensors (ground radar, optical mounts, telemetry pods) log in divergent coordinate frames, introducing multi-kilometer tracking uncertainty.

Runs within 0-malloc flight ring buffers to locally seal monotonic TAI truth states during blackout. Unifies range tracking radar (ITRF2020), hypersonic test articles, and orbital sensors (GCRS/BCRS) onto a single standardized 136-byte truth timeline for MACH-TB and Super Range corridors.
