• Abstract:
  The Global Positioning System (GPS) is fundamental to the critical infrastructure of the United States (US) and internationally. GPS is a fully operational service that provides a global source for accurate timing and positioning, 24 hours a day. GPS is presently used by aviation for the en-route and non-precision landing phases of flight. GPS is currently used within the US for precision approach and landings and is in the final stages of approval as a national and international standard. Companion GPS-based applications for runway incursion and ground traffic management are also underway. Additionally, GPS-based public safety systems and services are fielded. Planned or newer systems, such as Enhanced 911 (E911) and personal location and medical tracking devices are soon to be commercially available. Additional future systems are planned for land, marine and space applications. The US telecommunications and power distribution systems are dependent upon GPS for network synchronization timing. Further, GPS is a powerful enabling technology that has created new industries and new industrial practices fully dependent upon GPS signal availability and continuity. Several critical industries, both aviation and non-aviation, would incur adverse impact if there were degradation to GPS signal continuity and availability. UWB technology is based on very short pulses of radio energy. Its wide signal bandwidth yields excellent multipath immunity. UWB technology has potential in a variety of applications including communication and ranging, and is expected to see increased civil use in the future.
