Wetin Mek Yu GNSS Sayn De Fayl Ɛn Aw CRPA Anti-Jamming Antenas De Gi Di Sɔlv

If yu UAV, ɔtonamɛnt rɔbɔt ɔ motoka sɔm tɛm 'lɔs insɛf' na di map, nɔto yu wan de. Bɔku injinia dɛn kin kam fɔ no se ivin wit ay kwaliti GNSS risiva, dɛn sistɛm kin stil gɛt signal lɔs, big big jomp na pozishɔn, ɔ lɔng riakwishɔn tɛm. Bɔku tɛm, di rut kɔz nɔto di pɔsin we de tek am insɛf, bɔt na wetin kin apin bifo di signal rich am.

Insay dis atikul, wi de luk di rizin dɛn we kin mek GNSS nɔ wok na rial prɔjek dɛn – ɛn aw CRPA anti-jamming ɛntena dɛn kin ɛp yu fɔ gɛt kɔntrol bak.

Wetin mek ɔdinari GNSS ɛntena dɛn de strɛs na di mɔdan ɛnvayrɔmɛnt dɛn

Kɔnvɛnshɔnal GNSS ɛntena dɛn kin bi singl-ɛlimɛnt dizayn dɛn. Dɛn de trit di skay lɛk wan 'lisin pɔynt', we de amplify ɔltin we de rich da pɔynt de. Dis kin mek bɔku prɔblɛm dɛn de na di say dɛn we wi de tide:

1. Dɛn nɔ kin ebul fɔ no difrɛns usay dɛn de go

• Sataylayt signal ɛn intafɛreshɔn we de kam frɔm difrɛn say dɛn, dɛn kin miks togɛda.

• Strɔng lokal intafɛra kin izi fɔ ɔvawɛl wik sataylayt signal dɛn.

2. Dɛn nɔ gɛt ɛni spatial filta kapabiliti

• Filta na di men tin we dɛn kin du na frikshɔn, nɔto na di spes.

• Dis nɔ go du fɔ di jam dɛn we de nia ɔ narrowband/broadband intafɛreshɔn na ɔ nia GNSS frikshɔn dɛn.

Dis dɔn mek we UAV flay nia kɔmyunikeshɔn tawa, motoka pas nia lokal jama, ɔ rɔbɔt de wok na say we gɛt nɔys fɔ mek di industri, di GNSS frɔnt-ɛnd kin satrayt, we kin mek i nɔ gɛt bɛtɛ pozishɔn ɔ i nɔ ebul fɔ si am igen.

Tipik intafɛreshɔn sɛnɛriɔ dɛn na sivil aplikeshɔn dɛn

Frɔm wi ɛkspiriɛns wit sivil ɛn industrial kɔstɔma dɛn, GNSS fayl dɛn kin apin bɔku tɛm insay dɛn sityueshɔn ya:

• UAV dɛn we de flay nia bildin dɛn, bays steshɔn dɛn ɔ Wi-Fi-dense eria dɛn

• Savis rɔbɔt ɛn AGV dɛn we de wok klos to industrial RF ikwipmɛnt

• Kɔnɛkshɔn motoka dɛn we de sheb rod wit drayva dɛn we de yuz lɔw kɔst jam divays dɛn

• Infrastrakcha no dɛm we de na eria dɛm we gɛt ɔvalap kɔmyunikeshɔn sistɛm

Bɔku tɛm, intagreta dɛn kin sɔprayz fɔs se famwɔya ɔ map mistek de, bɔt bɔku tɛm we dɛn mɛzhɔ dɛn kin sho se di signal-to-intafɛreshɔn rɛsɛshɔn na di ɛntena pɔt jɔs tu smɔl fɔ mek di risiva wok fayn fayn wan.

Aw CRPA de ad di 'spatial dimɛnshɔn' we nɔ de.

CRPA (Controlled Reception Pattern Antenna) ad wan impɔtant kapabiliti we ɔdinari ɛntena dɛn nɔ gɛt: spatial selektiviti. Insted of wan element, wan CRPA array de yuz multiple elements en kam togeda dem signal intelligently. Tru dis, di sistɛm kin:

• Stia risepshɔn bim dɛn to GNSS sataylayt dɛn

• Fɔm dip nul dɛn to di intafɛreshɔn sɔs dɛn

• Dynamically adapt to chenj intafɛreshɔn dairekshɔn

Wi kכrant CRPA sכlushכn dεm, fכ egzampl, kin sכpכt 4, 8 כ 16 εlimεnt dεm, wit di nכmba כf simultaneously suprεs jam dεyshכn dεm tipikli bi 'nכmba כf εlimεnt − 1'. 4-elemɛnt arenjmɛnt kin stɔp 3 dairekshɔn, we 16-ɛlimɛnt arenjmɛnt kin ebul fɔ handle 15 dairekshɔn, insay in dizayn rɛnj.

Kɔmbayn wit robust hadwae dizayn (burnout protɛkshɔn ≥10 W na di RF input, IP65+ mɛkanikal protɛkshɔn, −40 °C to +65/70 °C ɔpreshɔn, ɛn ɔda tin dɛn), dis de mek GNSS risiva dɛn de yuz insay kɔndishɔn usay dɛn go ɔdasay fɔ fel.

Frɔm 'wetin mek wi lɔs GNSS?' to 'wi pas di tɛst'.

Fɔ bɔku sivil prɔjek dɛm, fɔ adopt CRPA anti-jamming ɛntena de chenj di tɔk frɔm riaktiv trɔbulshut to proaktiv robustnɛs:

• UAV flayt tɛst nɔ nid fɔ avɔyd sɔm eria dɛn igen jɔs bikɔs 'GNSS bad de'.

• Ɔtonom motoka dɛn kin mek dɛn kɔntinyu fɔ gɛt pozishɔn intɛgriti mɔ kɔnsistɛns along dɛn rod dɛn

• Indastrial rɔbɔt ɛn infrastukchɔ no dɛn kin bi less sɛnsitiv to RF ikwipmɛnt we de rawnd

Apat frɔm dat, wi intagreted anti-jamming yunit dɛn kin inklud wan bilt-in GNSS risiva we de autput PVT data (pozishɔn, velositi, tɛm) dairekt wan, we de mek intagreshɔn simpul fɔ tim dɛn we lɛk fɔ yuz mɔ turnkey aprɔch.

Wan prɛktikal nɛks step

If yu de dil wit GNSS rilaybiliti ishu dɛm naw, wan gud nɛks step na fɔ:

1. Kɔnfɛm if yu ɛntena we yu gɛt naw na simpul wan-ɛlimɛnt dizayn.

2. Mekɔp ɔ ɛstimat di intafɛreshɔn ɛnvayrɔmɛnt we yu sistɛm de fes.

3. Evaluate if 4-, 8- ɔ 16-elemɛnt CRPA ɛntena fit fɔ yu SWaP ɛn pefɔmɛns nid dɛn.
