Miniature Fo-Element Array  Integreted Navigation Anti-Jamming Yunit

 

1. Ɔvaviu

 

Dis dɔkyumɛnt de spɛsifa di prodak spɛsifikɛshɔn rikwaymɛnt fɔ di AJU-4050 Miniature Fo-Element Array Integrated Navigation Anti-Jamming Unit (we dɛn go kɔl naw di 'Anti-Jamming Unit').

 

Di Anti-Jamming Unit na men wan we gɛt wan arenjmɛnt ɛntena, wan anti-jamming prɔsesin mɔdyul, wan bilt-in risiva, ɛn sɔpɔtin kebul dɛn. I de sɔpɔt di risepshɔn, amplifyeshɔn, daun-kɔnvɔshɔn, filta, anti-jamming prɔsesin, ɛn ɔp-kɔnvɔshɔn autput fɔ 4-chanɛl signal dɛn na BDS_B1, GPS L1, ɛn Galileo E1 frikshɔn pɔynt dɛn.

 

Di bilt-in risiva de sɔpɔt PVT (Pozishɔn, Vɛlositi, Taym) sɔlvishɔn autput. I gɛt pawa saplai rɛnj we na DC9V~36V ɛn i ebul fɔ tinap agens 1 to 3 intafɛreshɔn dɛn we de kam insay difrɛn kayn dɛn lɛk brɔdband, narrowband, puls, ɛn frikshɔn swip sɔpreshɔn.
