GPS BIIR-5 (PRN 22), launched in 2003, transmits on GPS pseudo-random noise code 22 — one of the unique digital signatures that lets a receiver distinguish this satellite's signal from all 30-plus others broadcasting on the same frequency simultaneously. Block IIR satellites like this one were built specifically to replace the original 1980s-vintage Block II/IIA satellites as they aged out, carrying redesigned atomic clocks and enough onboard autonomy to maintain accurate positioning even during extended gaps in ground contact — insurance against exactly the kind of disruption that would matter most during a crisis.
