GPS Spectrum Importance • Radio interference affects a wide range of users and limits growth of new capabilities and applications • Without backbone GPS signals, derived performances and safety of life services will not function

Spectrum Use • GPS service frequencies – Radionavigation satellite signals currently provided in two frequency bands: 1575 MHZ (L 1) and 1227 MHz (L 2) • New civil GPS frequencies – New civil signals to be added at 1227 MHz (L 2) and 1176 MHz (L 5) – L 5 signal to feature higher power and ARNS protection to support safety of life navigation – Three civil signals will increase reliability – Space-to-space service (satellite control & positioning)

Spectrum Use • • E. U. proposal to overlay L 1, L 2, and L 5 U. S. primary objective: No impact or degradation to current users – Suggested overlay of L 5 -- designed to accommodate more than one system – Initial European opposition due to DMEs – Requested data on Galileo signal structure to analyze overlay feasibility – Requested E. U. plan for use of spectrum already planned for Galileo (E 1 -E 6)
