A -- Navigation and Timekeeping Technology

In accordance with the guidance promulgated by the Office of the Assistant Secretary of Defense (NII), concerning Navigation Warfare (NAVWAR), which deals with the mitigation of denial of Positioning, Navigation and Timing (PNT), this effort is concerned with the first two of the three elements: Electronic Protection (EP) and Electronic Support (ES). Please note, this effort does not address Electronic Attack (EA). Precision navigation and timekeeping are essential for many modern naval and maritime systems, and it is essential that navigation and timekeeping services be made available to platforms and weapons at the highest level of accuracy and with the highest possible confidence at reasonable cost. Lack of precise navigation and timekeeping technologies may jeopardize the success of military operations. For example, the Global Positioning System (GPS) provides highly accurate position/time information at low cost and, due to this, GPS has become the technology of choice for many users. Unfortunately, the GPS signal is a low-power signal that is susceptible to interference. Therefore there is a need for (1) affordable approaches to make GPS more reliable/robust, and (2) methods of quantifying threats to GPS performance that may be termed ?situational awareness? and (3) affordable and reliable precision navigation/timing alternatives to GPS. In the past six years, ONR has been conducting a series of Navigation and Timekeeping Science and Technology Projects in the following three technology areas; GPS Anti-Jam Technology, Precision Time and Time Transfer Technology, and Non-GPS Navigation Technology. In FY2009, the ONR Navigation and Timekeeping Technology Program seeks new and innovative navigation technologies that will provide more accurate, reliable, maintainable and affordable systems for Naval air, surface, subsurface and ground platforms and forces. Please see the attached full announcement for the areas of concentration available in this program.
