Shaving nanoseconds off inter-exchange financial corridors using geodesic ray-tracing and mountain relay towers.
By calculating geodesic line-of-sight paths across the English Channel and the Allegheny Mountains, relay tower positions minimize path length down to 0.01% of theoretical limits.
Real-time barometric pressure and humidity sensing calculates tropospheric radio refractivity, dynamically adjusting antenna tilt angles to track bent radio paths.
The Frankfurt-London ISAC microwave link achieved an audited one-way trading latency of 4.12 milliseconds, beating the fastest optical subsea fiber cables by 1.94 milliseconds.
