“…Narrowband jamming performs jamming in a random order or a sequential order (i.e., swept jamming), and generates tone or narrowband jamming signals by applying continuous waves. Also, it could perform multi-narrowband jamming (Armor 1998, Hua et al 2008, Kim 2013.…”

With the increase in the risk of GPS jamming, the development and application of anti-jamming GPS techniques have been actively performed. As the objective performance verification of developed techniques is important, equipment development for verification and discussion on anti-jamming performance test method and procedure have also been conducted. However, most tests are related to the specification of equipment and therefore detailed procedure of the performance verification of an anti-jamming system needs to be developed. In this study, requirements for anti-jamming performance verification were described, and test configurations and performance evaluation items depending on three kinds of test methods (lab test, basic outdoor test, and chamber test) were suggested for anti-jamming performance verification.

“…By using digital beam forming (DBF) technology, it suppresses different types of interference effectively at the direction distinct from the desired signal. There have been a large number of studies about array anti-jamming and a series of algorithms have been proposed which already proved effective [1,2,3,4]. However, due to the high sensitivity of the GNSS receiver, the RF front-end will be easily saturated.…”

Abstract. In order to solve the problem of interference in satellite navigation receiver, this paper proposes a two-stage cancellation anti-jamming implementation for GNSS system. Interference cancellation of the RF front-end can improve the saturation power point of the first-stage by more than 25dB, and two-stage cancellation can drop the interference signal power by 60dB. Practical tests shows that the anti-jamming performance of the receiver board increased by about 44dB. The system uses four-channel design and adopts power inversion (PI) and delayed least mean squares (DLMS) algorithms to calculate weights. The eventual system response time is proved in magnitude of us.

Global positioning satellite/inertial navigation system (GPS/INS) integrated navigation systems are widely used for many military applications due to their complementary features. It is normally assumed that the military GPS receiver will be used in a signal-jamming environment. Various anti-jamming techniques have been studied from the point of hardware and/or software. The velocity aiding method is a well-known software-based anti-jamming technique used for GPS/INS integrated navigation systems. The dynamics of the GPS receiver can be measured by an INS and then fed into tracking loops to reduce the tracking loop bandwidth to promote jamming resistance. The Korean government has been developing a GPS adapter kit (GAK) that can change a conventional bomb into a high-precision GPS guided bomb (GGB). In this paper, we introduce a GPS/INS integrated navigation system in a GAK, a velocity aiding method applied to the navigation system, anti-jamming test procedures and the results for a GGB. The test results show that the GPS/INS integrated navigation system using velocity aiding method can provide enhanced anti-jamming capability by efficiently reducing the tracking loop bandwidth.
