Global positioning system (GPS) is one of the key satellite-based radio technolo-gy providing navigational services on earth or near earth. The increasing usage of GPS applications in daily life has proved that students/researchers of many edu-cational departments including information and communication technology (ICT) are particularly interested to learn and visualize the GPS anti-jamming techniques in a simpler way in their major communication courses. It is a fact that GPS radio signal is vulnerable in various ways to jamming signals launched by malicious el-ements. The traditional available GPS anti-jamming techniques generally involve either added hardware and/or computational complexity which introduce difficul-ty for students to understand the basic concepts. As an alternative, this paper pre-sents a simpler GPS anti-jamming system kit based on L1-band (1.575 GHz) of GPS for education purpose. More specifically, the proposed antenna array, inte-grated with two couplers, cancels out the jamming signal in radio frequency (RF) domain using sum and difference patterns generated by the latter. The simulated and measured results, in terms of scattering parameters and power profiles, of the proposed system have shown that the jamming signal can be eliminated with less complexity. Eventually, the proposed GPS anti-jamming system has great poten-tial to be used in ICT related disciplines for learning and training purposes.
