Guidance Integrated Fuze (GIF)
The Guidance Integrated Fuze (GIF) was a Technology Demonstration Program at NSWCDD Sponsored by OSD-ATL. GIF was being co-developed by the Army & Navy as the design concept for the Army Course Correcting Fuze (CCF) Program. The US Army developed a requirement for Course Correcting Fuze(CCF), with OPM CAS as the developer for USAFAS. GIF Technology will greatly reduce the number of rounds (20:1) required to defeat a given enemy threat. GIF corrects the ballistic trajectory in 2D, resulting in a small terminal miss distance. GIF provides "First Round "First Round - Steel on Target" Steel on Target".
The Guidance Integrated Fuze (GIF) is a low cost fuze that replaces a NATO standard fuze on existing stockpiles and reduces the number of rounds need to defeat targets by a ratio of 20 to 1. The system relies on commercial off-the-self (COTS) GPS technology to accurately guide the artillery to the desired targe -- it uses COTS based power, telemetry, sensor, flight processor, actuator and nose roll bearing systems. The GIF is intended to replace the existing NATO standard multi-option fuze for artillery (MOFA) and t. GIF technology can be applied to literally literally millions of existing millions of existing 155mm, 105mm, 5", 76mm projectiles, and 120mm and 81mm mortars.
The U.S. Navy Guidance Integrated Fuze (GIF) system, sponsored by the Office of Secretary of Defense, employed a novel systems approach that integrates GPS-based, guidance, navigation and control functions (GN&C) into a NATO standard fuze envelope. GIF is a "smart fuze" that is designed to be a one-for-one replacement to the NATO Standard Fuze presently used by the US Army, Marines, Navy and many NATO countries. Prior to the GIF initiative, the packaging of these elements represented a serious challenge and was considerably beyond the state-of-the-art of SAASM (Selective Availability Anti Spoof Module) GPS receivers and GPS anti-jam systems. The GIF system addresses these needs and is projected to dramatically improve the accuracy of ballistic trajectory of the projectiles which will result in significant performance improvements including: minimal miss distance, reduced time to neutralize threats and minimized logistic and re-supply burdens. In other words, GIF will enable "Maneuver Warfare" and provide "First-Round Steel-Target" capability. FY 2003 Accomplishments included a completed initial fuze design. Completed 4 roll bearing test fuze gun firings. This verification testing was important to prove that the COTS based components could survive gun launch. Static wind tunnel testing was completed in September 2003.
FY 2004 Plans included seven flight tests. Based on the success of that test, a contract award was planned for the development of miniature M-code GPS receivers, which is funded outside the QRF work. The Army and Navy both planed to procure these fuzes beginning in FY 2006. There were no plans to fund this project in FY 2004 from the FY 2004 Quick Reaction Special Projects Program.
On 06 February 2004 Mayflower Communications Company, Inc. a technology leader in GPS and Communication Data Link technologies, headquartered in Burlington, MA was awarded a Small Business Innovation Research (SBIR) Phase III contract totaling $10.4 million from the Naval Surface Warfare Center (NSWC), Dahlgren, VA. The Navy DoD SBIR Program is a highly competitive program that funds advanced R&D projects geared towards meeting DoD objectives at small technology companies, which also have the potential for commercialization in the private sector and/or military markets. The DoD SBIR program funded projects totaling $834 million in FY 2003. The funding will be used by Mayflower to develop the necessary modules to support the successful deployment of the U.S. Navy Guidance Integrated Fuze (GIF) system sponsored by the Office of Secretary of Defense.
GIF Spiral II development requires significant miniaturization of next generation (M-code compatible) GPS receivers with robust anti-jam capability as well implementation of GPS SAASM (Selective Availability Anti-Spoof Module) function in software. Under this program initiative, Mayflower will develop the critical GPS modules for the next generation M-code compatible GPS (Global Positioning System) receivers and anti-jam systems for the Spiral II GIF program. Successful development of these GPS modules will drive the cost of precision navigation and guidance systems down to approximately $ 3,000 per round and reduce the number of required rounds per target by a factor of 30 to 60, with a similar reduction in time required to achieve this goal. According to Mr. Chad Finch, the Navy GIF Acquisition Program Manger, "the Spiral II GIF program will not be successful without a robust GPS anti-jam capability sufficiently miniaturized to fit the GIF envelope. A miniature M-code compatible Software SAASM GPS receiver system with robust anti-jam is essential. This development will greatly abate these crucial problems."
Mayflower's development of the miniaturized GPS SAASM module with robust anti-jam capability for the GIF program builds on its successful track record of developing and demonstrating its advanced GPS receivers, anti-jam and data link technology prototypes in a variety of Navy programs. According to Mr. John Fraysse, the Gun and Projectile Technology Director for Naval Surface Fire Support (NSFS) missions at NSWC, "This important initiative will demonstrate the superior GPS technology required for a successful GIF product. This will be accomplished by a true Government-Industry partnership between NSWC and innovative, small businesses such as Mayflower. The AJ concept and integrated GPS receiver technologies 'raise the bar' with respect to the present state-of-the-art for small body projectiles and missiles and has general application to low-cost airframes being developed in the Navy and Army Tech Base programs."
Mayflower had supported the U.S. Navy's goal of enhancing the accuracy of Navy Precision Guided Munitions for over a decade starting from its early work for the Naval Research Laboratory (NRL) dealing with advanced GPS navigation and attitude receivers to more recent work for the Office of Naval Research (ONR), NAVAIR (Patuxent River and China Lake) and NAVSEA (NSWC, Dahlgren) in GPS anti-jam (A/J) electronics, and command data link for retargeting." The U.S. Navy's strong support and confidence in our technology and business is deeply gratifying. It is a testament to our strength in GPS. Our proven track record of successful R&D work for the Navy, as well as our ongoing R&D work for the US Army CECOM and AMCOM, has culminated in Mayflower being selected by the US Navy NAVSEA Command, Dahlgren Division for this important Navy GIF program initiative." said Dr. Triveni Upadhyay, Founder and Chairman of Mayflower Communications Company.
Toyon Research Corporation developed a low-cost miniature anti-jam GPS integrated communications (MAGIC) antenna system for the guidance integrated fuze (GIF). Toyon's MAGIC (T-MAGICT) antenna system provides an anti-jam (AJ) GPS capability and, in its simplest incarnation, is comprised of two antenna elements that fit within an ogive trapezoidal volume that is only 0.093 inches thick. Including the electronics, the T-MAGIC system occupies less than 0.5 cubic inches. A sophisticated form of the T-MAGICT system has two electronically reconfigurable antenna elements and a closed-loop RF interference (RFI) suppression system. The two element system provides good anti-jam protection (nulling) for the GPS receiver without consuming more that 150 mW of power. The electronically reconfigurable system is designed maintain optimal performance across large temperature variations. The first generation T-MAGIC systems have already been successfully launched and operated at rotations of up to 180 Hz. The anti-jam GPS capability has been tested at White Sands Missile Range.
Achieving good RFI rejection is becoming significantly more difficult as military and civilian electronic systems become smaller, lighter and cheaper. The very small footprint of the T-MAGICT antenna system makes it ideally suited to meet the needs of current and future military and commercial GPS and communications systems that have stringent space and cost requirements. The T-MAGIC anti-jam capability boosts the robustness of precision guided munitions, reduces the possibility of collateral damage, and increases the probability of achieving mission goals with a lower cost. The technology used to develop the T-MAGICT antenna system is also applicable for any military or commercial wireless system that is subjected to electromagnetic interference (EMI) such as GPS aided aircraft navigation systems, wireless local area networks or wireless communications including cellular communications systems.
By January 2005 the Guidance Integrated Fuze (GIF) program was the major constituent of the Navy's Non-Nuclear Expendable Ordnance (NNEO) (PE 0603609N Conventional Munitions Project 2299): budget line, representing $25M annually in FY04-FY06, and $10M annually from FY07-FY11. Other NNEO programs include the Multi-Function Fuze (MFF) P3I and the Extended Range Propelling Charge.
In FY2004 GIF ($25M) awarded two contracts for developing the GIF baseline design for high rate, low cost production. Evaluate 10 fuzes from each contractor in laboratory and simulated gun launch conditions to assess guidance, navigation and control features, conventional fuzing functions and shock survivability. Formally document all design and test data and provide to both contractors.
For FY2005 ($25M) GIF completed two additional design-build-test cycles, resulting in each contractor providing 25 (Jan 05) and 100 (Aug 05) fuzes for government evaluation. Perform the full spectrum of laboratory, simulation and gun launch tests to determine the best design. Award 1,250 fuze option to one contractor (September 2005).
FY2006 Plans ($25M) for GIF were to have 1,250 GIFs delivered (April 2006): 150 for acceptance testing and 100 for operational assessment. The remaining 1,000 GIFs will be production representative hardware suitable for Field Training and Follow-on Test and Evaluation, as necessary. FY2007 plans ($9.288M) for GIF were to complete qualification tests of downselected GIF design. Conduct Preliminary Design Review and Test Readiness Review in preparation for Developmental Test (DT-IIB). Conduct initial user evaluation followed by TECHEVAL.
On 05 October 2005 it was announced [Solicitation Number N0017806R1002] that the Naval Surface Warfare Center, Dahlgren Division intended to competitively procure the design, development and manufacture of the Guidance Integrated Fuze (GIF). GIF is a low-cost smart fuze that adds guidance and control to traditional fuze functions into the NATO standard fuze shape to correct the trajectory of a projectile to improve accuracy.
