AbstractToyon Research Corporation proposes to develop a low-cost miniature anti-jam GPS integrated communications (MAGIC) antenna system that is compatible with the guidance integrated fuze (GIF) electronics package. The GIF is intended to replace an existing NATO standard multi-option fuze for artillery (MOFA) and will rely on commercial off-the-shelf (COTS) GPS technology to accurately guide the artillery to the desired target. The MAGIC antenna system will provide an anti-jam (AJ) GPS capability and, in its simplest incarnation, will be comprised of two passive antenna elements with customized patterns that, when differenced, result in a ground nulling gain pattern. A more sophisticated form of the system will have two electronically reconfigurable antenna elements and closed-loop RF interference (RFI) suppression. Toyon will pursue an aggressive 18-month development schedule that will minimize risk by incrementally improving the capabilities and sophistication of the proposed miniature AJ GPS antenna system. We will design, build and test the first-generation prototypes of the MAGIC antenna system within the first six months of the program and we will deliver gun-launchable demonstration prototypes of the system within the next three months. Toyon will incorporate the active element closed-loop RFI suppression electronics to improve the anti-jam GPS performance of the system in the following nine months.
