Survivable SWaP-C Optimized GN&C (S2GNC) Electronics Package for EM Railgun INP Program Navy SBIR FY2012.1 Sol No.: Navy SBIR FY2012.1 Topic No.: N121-102 Topic Title: Survivable SWaP-C Optimized GN&C (S2GNC) Electronics Package for EM Railgun INP Program Proposal No.: N121-102-0301 Firm: Mayflower Communications Company, Inc. 20 Burlington Mall Road Burlington, Massachusetts 01803 Contact: Triveni Upadhyay Phone: (781) 359-9500 Web Site: www.mayflowercom.com Abstract: The overall objective of this Navy SBIR program is to develop a high-integrity survivable Guidance, Navigation and Control (GN&C) electronics package that will meet the stringent navigation system performance requirements of the EM railgun INP program, fit within a small size, weight and power and cost (SWaP-C) budget, and is survivable under high g shock, high temperatures and electromagnetic fields envisaged for the EM railgun environment. The proposed Mayflower GNC package will be designed to meet the above Navy program objectives. In the Phase I feasibility study Mayflower will analyze the navigation and guidance accuracy of the integrated system in high g shock, high dynamics and high GPS jamming environment. The Phase I study will also evaluate the packaging concept for survivability and develop a system design approach that can be implemented in prototype hardware in Phase II. The Phase II prototype GNC system will be tested and its performance characterized at NAVSEA. Benefits: The military benefits of the proposed GNC electronics package is that it addresses a major vulnerability of the EM railgun projectiles to the emerging GPS jamming threat. Having a GNC package that is qualified for a much harsher environment opens the door to meet many DoD projectile/mortar applications at an affordable cost because of the larger projectile market size. The novel electronics packaging concept developed under this SBIR program will find many commercial applications where g shock is a common occurrence. The high integrity robust GNC package will also find commercial applications where reliable and precision navigation accuracy is demanded, such as civil aviation. Return
