SUBJECT:

 

Market research is being conducted to identify potential sources that may possess the expertise, capabilities, and experience to perform production, sustainment, modification and engineering services to support the Advanced Digital Antenna Production (ADAP) and Global Positioning System Antenna System-1 (GAS-1). There are twelve (12) National Stock Numbers (NSNs) involved in this market research: NSN 5985-01-352-9676, 5985-01-601-2647, 5985-01-506-5380, 5985-99-464-9559, 5985-01-554-5162, 5985-01-514-5464, 5985-01-530-3257,  5985-99-958-0805, 5985-99-371-2158, 5985-01-531-1792, 5985-01-554-5163, and 6625-99-463-6856.

 

ITEM DESCRIPTION

 

This acquisition is in support of the ADAP and GAS-1 system.

GAS-1 for aircraft is composed of two individual Line Replaceable Units (LRU's); (1) an AE and (2) a CRPA.  GAS-1 for ships is composed of three individual LRU's; (1) an analog AE, (2) a CRPA, and (3) a Ground Plane Enclosure (GPE).  The GPE can be ordered with or without a Fiber Optic Antenna Link (FOAL).  When all three LRUs are integrated, it is referred to as Ground Plane Assembly (GPA) but is not identified as an upper level assembly with its own NSN.  For purposes of this LCSP the GAS-1 GPA/GPE is referenced here but is not included as part of the LCSP, the Navy manages it separately.

 

The ADAP is an anti-jam antenna electronics system that ensures continued and uninterrupted availability of GPS signals to aircraft and ships. The ADAP system consists of three Line Replaceable Units (LRUs) - a seven element Controlled Reception Pattern Antenna (CRPA) unit and its associated Antenna Electronics (AE) unit. The Ground Plane Assembly (GPA) combines the CRPA and AE with a Ground Plane Enclosure (GPE) for mounting the system on the mast of ships. The GPA comes with or without Fiber Optic Antenna Link (FOAL).  The ADAP AE is a; complex system which requires extensive qualification and acceptance testing to ensure appropriate ant-jam and satellite tracking performance. Current test equipment for the ADAP AE system is completely proprietary to Raytheon Systems Limited (RSL), as is all embedded software. RSL certified the integration and operational performance of the Harris (formally EDO) CRPA with the RSL AE.

ADAP implements advanced digital anti-jam processing to mitigate the effects of multiple types of jamming and interference waveforms, including repeater jammers, in highly stressed interference environments simultaneously in the L1 and L2 GPS frequency bands. ADAP is compatible with the legacy and modernized GPS signals and provides protection across the M-Code bandwidths.

 

IMPEDIMENT TO COMPETITION

 

The original equipment manufacturer for this item is Raytheon Systems Limited (RSL) in the United Kingdom (CAGE K0268). RSL is the designer and developer of both the GAS-1 and ADAP systems and as such owns the proprietary rights to the drawings, design, manufacturing data, software and unique test equipment required to manufacture and repair these assets. Additionally, RSL is the only known contractor with the experience and in-depth knowledge of the functions and intricacies of the GAS-1 and ADAP systems, its interface with the multiple platform configurations, and specialized test equipment.

The Global Positioning System (GPS) Antenna System-1 (GAS-1) system was a follow-on acquisition to the Antenna Electronics (AE) and Controlled Reception Pattern Antenna (CRPA) contracts with E-Systems.  GAS-1 is form, fit, function, and backward compatible with the existing AE, CRPA and GPS User Equipment.  The GAS-1 Antenna Electronics provides Anti-Jam (A-J) capability to "null" out noise sources through null steering of the signal reception of individual elements in the GAS-1 antenna. The GAS-1 system was specifically oriented to satisfy that requirement by incorporating low risk, NDI technology

The ADAP was procured as a Non-Developmental Item (NDI). No drawings or other technical data (e.g. source code) required to foster competition were acquired. Procuring this system competitively may require any other source to reverse engineer the current ADAP system resulting in duplication of cost and a minimum 24-month program delay associated with production, qualification test, and platform integration. Such delays would not support the install schedules of various Air Force, Navy, and FMS users. Additionally, the program office does not have the engineering funds to accomplish a reverse engineering effort.

Due to increased hostile threats of GPS jamming in current and future theaters of operation, and the critical role of GPS in naval warfare operations and precision weapons guidance, the government must procure anti-jam capability for all air and surface platforms at the earliest possible date.

 



 

INTEREST

 

The DLA/AWB Contracting Office intends to award a sole source contract to RSL for the procurement, repair, technical and engineering support of the ADAP program. Other interested parties may identify their interest and capability to respond to the requirement no later than 8 April 2019 by emailing april.walls@us.af.mil or dla.dlr.proc@us.af.mil. The Government intends to procure these items using Other Than Full and Open Competition as prescribed by FAR 6.302-1, Only One Responsible Source and No Other Supplies or Services Will Satisfy Agency Requirements.
