摘要

1. Telecommunications networks and the electric power grid, two critical elements of the nation's infrastructure, both heavily rely on GPS to meet thejr timing requirements. In many cases, they have no redundant source of timing, other than the holdover capability of their GPSDOs.rn2. The length of a GPS outage that can be tolerated often depends entirely on the type of GPSDOs being used. While some devices can meet requirements for hours or days without GPS, others will likely be out of tolerance within seconds or minutes.rn3. Because industry now depends so heavily on GPS timing, the deployment of a redundant timing system in as short a time frame as possible seems to be in the best interests of the United States.rn4. LORAN, in its modernized form, can meet all existing industrial timing requirements, and seems to be the logical choice to fulfill that role.
