Sensor Detection Range Calculator

Updated: v2026.02.13

Calculate detection ranges for all three Aurora sensor types: passive thermal, passive EM, and active gravitational. Compare up to 2 configurations side-by-side. All formulas and tech values are verified against the Aurora game database (AuroraDB.db v2.7.1) and referenced in the manual.

Formulas used:
Passive Range (km) = sqrt(Size_HS * Tech_Value * Signature) * 250,000 — ref A-12
Active Range (km) = sqrt((Strength * HS * EM_Sens * Res^(2/3)) / PI) * 1,000,000 — ref A-16
Off-Resolution = Base_Range * sqrt(Target_HS / Resolution) — ref A-12
Thermal Sig = Engine_EP * Thermal_Reduction_Multiplier — ref 11.1-1
Cloak Effect = Signature * (1 - Cloak% / 100) — ref 11.4-1
Jammer Effect = Range * max(0, 1 - (SJ - ECCM) * 0.1) — ref A-17 (active sensors only; passive thermal/EM sensors detect emissions and cannot be jammed)
