Uncollected overflight fees and unmonitored EEZ activity cost coastal and island nations millions every year. Sovereign Horizon uses satellite ADS-B and AIS telemetry for full revenue recovery: find the leakage, bill it, collect it. It starts with a 90 day audit at zero cost to the state.
Own Your AI. On premise or sovereign private cloud. Your data never leaves the country.
Under ICAO Doc 9082, every commercial aircraft crossing your flight information region owes en route charges. Under UNCLOS, your exclusive economic zone carries economic rights up to 200 nautical miles offshore. The traffic is there. The billing loop is not.
Legacy systems miss overflights. No tail number capture, no MTOW match, no invoice. The aircraft passed. The fee did not.
Coastal radar sees a fraction of your waters. Beyond its reach, unlicensed fishing and unrecorded extraction operate in the open.
Manual reconciliation cannot keep pace with thousands of monthly crossings. The gap compounds quietly, year after year.
ICAO Doc 9082
Charge = Distance × Weight × Unit Rate
Under ICAO Doc 9082 charging principles, the standard formula is Charge = Distance Factor x Weight Factor x Unit Rate. Sovereign Horizon reconciles satellite ADS-B tracks against your billing records and flags every flight that was never invoiced.
Great circle kilometers flown through your FIR, divided by 100.
The square root of the aircraft's certified MTOW in metric tons, divided by 50.
The cost recovery fee your state sets for air navigation services.
