The Department of Transportation, Federal Aviation Administration has a requirement for DVT Sustainment Program.

Implementation of Global Navigation Satellite System (GNSS) technology provides Performance Based Navigation (PBN) enabling aircraft to fly more direct routes and procedures facilitating a more efficient use of the available airspace.  The transition to PBN enabled by GNSS allows the services provided by DME and VOR Navigational Aids (Naveed’s) to transition from being a primary source of navigation to a backup for GNSS as part of a resilient NAS infrastructure.  The resilient navigation infrastructure consists of DME, VOR and TACAN systems installed at Service Delivery Points (SDPs) in various configurations, to include:

• VOR (conventional or Doppler):  The FAA will repurpose the VOR Network to provide a basic conventional navigation backup for aircraft during GNSS disruptions.  This enables one-third of the VORs to be discontinued in the implementation of a VOR Minimum Operational Network (MON).  SDPs may have a VOR, VOR with DME (VOR/DME) or VOR with TACAN (VORTAC)
• DMEs:  High Power DMEs (HPDMEs) provide an Area Navigation (RNAV) capability for aircraft with scanning DME receivers.  Most of the HPDMEs are collocated with VORs at VOR/DME sites.  There will also be a small number of SDPs with DME only.  Low Power DMEs (LPDME) are installed with Instrument Landing System (ILS) and are not part of the DVT Program
• TACAN: Provides azimuth and range information for DoD aircraft and range only for civil aircraft for RNAV.  Most of the TACANs are collocated with VORs at VORTAC sites

• The Contractor must comply with requirements contained in FAA-E-37012, Performance Specification Very High Frequency (VHF) Omnidirectional Radio Range (VOR) System – Conventional (CVOR) and Doppler Equipment; FAA-E-37016, Performance Specification Distance Measuring Equipment (DME) Transponder System; FAA-E-7870, Performance Specification Tactical Air Navigation (TACAN) Ground Transponder System; the requirements included in this SOW; and the respective TO(s)/DO(s).
• The Contractor must deliver the DVT Systems in accordance with (IAW) the respective Performance Specification and the data referenced in the Contract Data Requirements List (CDRL) IAW the respective TO(s). Anticipated CDRLs under this Contract are located within Attachment J-4. All data deliverables must be prepared and delivered IAW the corresponding Data Item Description specified in the CDRL. Unless otherwise specified, the Contractor must deliver all CDRLs IAW Sections 12, 14, and 16 of the CDRL. The FAA Contracting Officer (CO) or the designated Contracting Officer’s Representative (COR) must approve all items delivered in response to this SOW or as described in the TOs. All references to the “FAA” in this SOW, or as described in the TOs, mean by the authority of the CO or designee. TOs/DO(s) are, without limitation, anticipated to include one or a combination of the services, deliverables, or subject matter solutions listed in the following sections.
