High Frequency Geolocation and Characterization (HFGeo) Phase 1B BAA Questions

#QuestionAnswerDate Posted
001 How many awards are you anticipating? How large will the awards be? These questions are addressed in IARPA Frequently Asked Questions B1 and B2 at: http://www.iarpa.gov/faq.html. There is no predetermined award size or number of awards. 11/01/12
002 Can we submit a proposal as a prime and also be a subcontractor on a proposal submitted by another organization? Offerors may submit a proposal as a prime and as a subcontractor, but consistent with IARPA FAQ T1 at http://www.iarpa.gov/faq.html, "an individual or organization associated with multiple teams must take care not to commit more resources than can be effectively applied to the program under the BAA to which they are proposing." 11/01/12
003 Since back propagation can be closely tied to geolocation and the focus of this BAA is not on geolocation, must our techniques be capable of both forward and backward ray tracing? As described in Section 1.A.1, “The system must provide the ability to propagate rays from a source location to a specific receive point as well as back-propagate signals from a receive location given observed angles of arrival….” As described in Section 1.A, “In later phases of the program these technology innovations will be further developed and integrated into geolocation and source characterization applications.” 11/01/12
004 Who should we contact if there is an administrative question about accounts or proposal submission through the IARPA IDEAS web site? A help desk is able to provide assistance. The helpdesk is available to answer questions by phone Monday-Friday from 8:00am to 5:00pm EST, or by email by filling out an on-line form. The phone number is: 1-855-235-0558, and the on-line form can be found at: https://iarpa-ideas.gov/client/HelpDesk/HelpDesk.aspx. 11/01/12
005 How close are the GFI reference sources to the sites that will be used for testing the performer developments? Is a local ionospheric model using reference source near the signal of interest sufficient? As described in Section 1.A.1 on page 5, "The system shall be capable of predicting propagation for signals from multiple distinct emitters arriving from different azimuth and elevation angles simultaneously." An ionospheric model that is local to a specific emitter will not meet that goal. Therefore, the government reference sources will be at a variety of distances and directions relative to the location of the test sources. 11/01/12
