product presentation

 As a general positioning and navigation system, GPS system is getting more and more attention because of its incomparable advantages. Especially with the global popularization of UAV, the dependence on GPS positioning and navigation is increasingly obvious; in the application confrontation in many hot spots, the application of UAV has the demand of interference and anti-interference. When the satellite signal reaches the ground user receiver, it is quite weak (about-130 dBm), the weak interference may cause the GPS receiver to reduce the system accuracy to work normally and lose the navigation ability. GPS anti-jamming technology has become a key problem to be solved in the practical application of satellite navigation receiver in special industries.

For a GPS receiver to receive high quality satellite signal, it must get high quality reception gain, and eliminate interference from other signals as possible.

main features

u     Adaptive antenna array: four L1 B1 GPSBDS adaptive antennas are used to form an array, and the adaptive filter adaptive antenna is aligned with the satellite source

u     Small volume and light weight: low section, small size anti-interference ceramic antenna array, small volume, light weight, conducive to installation, small bearing ratio

u     Adaptive signal processing: automatically control the antenna array to adjust the parameters and direction, keep the main antenna beam opposite to zero finger, strong anti-interference ability

u     High inhibition and strong anti-interference: high inhibition characteristics, single interference three interference, strong anti-interference ability

u     Low noise playback, low elevation angle and high gain: good polarization between the antenna unit characteristics, with low noise playback, high gain, stable performance

u     Small mutual coupling between antenna array array: with multi-stage anti-interference module technology to the receiver end, effectively against the pulse sweep interference equipment

u     Simple installation and application: integrated design, only need to replace the original machine GPS antenna interface, the original machine 9-36V wide voltage power supply can be applied

u     Support multi-system expansion: in addition to supporting GPS-L1 BDS-B1 segment application, L2 / L5 and GL ONASS G1, BDS-B2 and GALILEO systems can be expanded

u     Customized design: provide customized design scheme according to different satellite systems in multiple regions of the world

u     All localization: all chips are designed and applied in localization, and the MPGA kernel is developed independently
