The Defense Advanced Research Projects Agency?s (DARPA) Special Projects Office (SPO) anticipates releasing two Broad Agency Announcements (BAAs) during late April 2005 for the Robust Surface Navigation via Signals of Opportunity (RSN) and Sub-Surface Navigation via Signals of Opportunity (SSN) programs. These two programs, combined, represent the concepts of interest stemming from the Request for Information (RFI) released 11 Feb 2004 entitled Geo-location and Navigation via Signals of Opportunity (NAVSOPP). The overall goal of these programs is to extend our geo-location and navigation capability to areas where GPS does not provide adequate capability, and to provide these services under conditions of GPS denial. Phase 1 of each program will consist of identification and assessment of potential exploitable signals, followed by analysis and performance modeling, measurement-based concept validation, and preliminary design. In Phase 2 the program performers whose designs are selected from Phase 1 will conduct final design, build, and test of prototype receivers and other supporting infrastructure for navigation using the signals of opportunity and special beacons, where required. This will include demonstration of a non-form/fit functional prototype system in multiple environments. The specific goal of the RSN program is to develop technologies that will enable our warfighters to have GPS-like navigation under conditions of GPS denial and in difficult environments where GPS does not provide adequate performance. These environments include inside buildings, urban canyons, and under dense foliage. Since GPS signals do not penetrate or are obscured by multipath propagation in these environments, RSN expects to use existing terrestrial and space based signals (such as broadcast TV, AM/FM radio, and cellular phone networks) as a basis for navigation. A key desired feature is the ability of the system concept and architecture to exploit these signals as globally and as non-intrusively as possible. DARPA envisions the capability to span the range of user platforms from airborne fast-movers to sensors and ground forces in urban interiors. It should use a layered approach that uses, for example, signal-of-opportunity ?calibration reference? ground stations at maximum practicable standoff for wide area coverage, but that can easily and smoothly transition to more intrusive active beacons as necessary to augment the signals of opportunity when they are inadequate for the task. The specific goal of the SSN program is to develop technologies that will enable our warfighters to have GPS-like navigation and stationary asset geo-location in sub-surface environments such as underground facilities, tunnels, mines, and unimproved caves. Ideally, SSN would use existing ?signals of opportunity,? as RSN does. However, DARPA realizes that very few signals penetrate the ground enough to be usable. Thus the SSN program recognizes that purpose-deployed signal beacons and inertial navigation sensors or other augmentation will take on a greater role, and that the characteristics of these solutions are likely inconsistent with a more general receiver and architecture that make it a broadly applicable and efficient global solution for all above-ground navigation, as in RSN. SECURITY: Work under RSN and SSN will be classified at the collateral SECRET level. Proposers must have the required United States personnel clearances, cleared facilities, storage, and processing capabilities to submit a proposal for this solicitation. DARPA intends to hold a Proposers? Day Briefing for the RSN and SSN BAAs on 11 May 2005 at the Booz Allen Hamilton conference facility in Arlington, VA. Attendance is limited. Potential proposers should indicate their interest via e-mail to SN05-21@darpa.mil. This meeting will be classified SECRET. All attendees at the Proposers? Day Briefing must be pre-approved and pre-registered, including having valid United States security clearances in place before the meeting starts. The deadline for receipt of classified visit certifications is 4 May 2005. All questions regarding attendance should be emailed to SN05-21@darpa.mil.
