Abstract: BeiDouandGPSreceiversaresusceptibletointerference.Inordertoimprovetheperformanceofthereceiverunderstrongjammingenvironment,theeffectsofdifferentarraysanddifferentalgorithmsontheanti-jammingperformanceofthereceiverwerestudied.AnantijammingplatformforBeiDouandGPSdual-modereceivingsystemwasdesignedandimplemented
onthebasisofGPSantiinterferenceresearch.Theexperimentalresultsshowthatbythissystem,theBeiDouandGPSdualmodereceiverscansearchupto6BeiDounavigationsatellitesand5GPSnavigationsatellites,andlocateundertheenvironmentof-30dBmstronginterference.Thesystemcanalsobeextendedtoavarietyofsatellitenavigationreceiversanti-jammingplatform.
