GPS BIII-9 (PRN 20), part of GPS's most significant hardware redesign in decades — the generation built after Selective Availability was already permanently switched off in 2000, giving these satellites an anti-jamming capability roughly eight times stronger than any previous GPS generation, engineered specifically for an era in which cheap commercial GPS jammers had become widely available to anyone wanting to disrupt precision-guided navigation.
