- Description
- This is a SOURCES SOURGHT SYNOPSIS. THERE IS NO SOLICITATION AVAILABLE AT THIS TIME. REQUESTS FOR A SOLICITATION WILL NOT RECEIVE A RESPONSE. This SOURCES SOUGHT SYNOPSIS is in support of a market survey being conducted by the USAF Air Traffic Control And Landing Systems, ATCALS, program office to determine the existence of potential sources capable of providing an alternative design for the AN/GPN-22 POTENTIOMETER. This effort will provide modification designs for the AN/GPN-22 Precision Approach Radar alignment process. The alignment of the AN/GPN-22 precision approach radar antenna is performed through a simple feedback circuit using discrete potentiometers (NSN 5905-00-517-9412). The current potentiometer circuit is used to align the antenna with up to four runways. Initially, the technician manually aligns the antenna. Once the manual alignment is complete, then the antenna can automatically be moved. During the manual alignment, a reflector is set up on each runway. To align the antenna, the technician looks through the telescope on the antenna. The technician then rotates the antenna until the reflector is centered in the telescope. An electric motor is used to rotate the antenna. Varying voltages control which ?step? the motor is set to. This allows for rotation of the antenna to very precise angles controlled by an input voltage. When the technician ?sees? the reflector in the telescope, then he records the voltage needed at that particular angle. The technician then repeats this process for each runway needed. The potentiometers are used to control the output voltage going to the motor. This allows for automatic alignment of the antenna by selecting one of the four potentiometers. An alternative design would remove, as a minimum, the noted discrete potentiometers and maximize the ease of use in the antenna alignment procedure. As noted above, the alignment procedure records the voltage of the motor for a particular runway (up to four). When the technician selects one of four runways, the recorded voltage for that runway is sent to the motor. The voltage determines the ?step? of the motor, which in turn, controls the angle of the antenna. The alternative design shall be modular to facilitate maintenance and logistics support. The use of mature, commercial off-the-shelf technology is encouraged to minimize cost and program risk. Proposed solutions must be integrated into existing hardware and operate within the temperature range of -32 to 120 degrees Fahrenheit. Digital or analog designs may be proposed. All proposed designs must meet the requirements of Mil-Std-188-124. Proposed solutions shall be submitted in a Microsoft Word, PowerPoint, or Adobe file format. Preliminary drawings or schematics must be provided to illustrate the proposed design solution. A Rough Order of Magnitude (ROM) cost and schedule estimate to design, build, and test a prototype is also mandatory. The submittal of engineering test data is encouraged to assist the government evaluate the maturity of proposed design solutions. An Ombudsman has been appointed to hear concerns from offerors or potential offerors during the proposal development phase of this acquisition. The purpose of the Ombudsman is not to diminish the authority of the program director or contracting officer, but to communicate contractor concerns, issues, disagreements, and recommendations to the appropriate government personnel. When requested, the Ombudsman will maintain strict confidentiality as to the source of the concern. The Ombudsman does not participate in the evaluation of proposals or in the source selection process. Interested parties are invited to call the Ombudsman at (405) 736-3273. DO NOT CALL THIS NUMER FOR SOLICITATION REQUESTS. Any information submitted by respondents to this synopsis is strictly voluntary. The Government will not pay for any information that is submitted in response to this SOURCES SOUGHT request. This synopsis request is in support of a market survey to determine the existence of potential sources only. All interested firms are requested to submit their statement of qualifications, along with any supporting documentation to 327 CSSG/PKB, 3001 Staff Drive, Ste 2AB1-103C, Tinker AFB, OK Attn.: Mr. David Hancock, Contracting Officer. Responses should be received not later than 30 days after the date of this publication, and should not exceed ten (10) pages. This synopsis neither constitutes a Request for Proposal, nor does it restrict the Government as to the ultimate acquisition approach, and should not be construed as a commitment by the Government for any purpose.
