Active Vs. Passive GPS Antennas
Global Positioning System (GPS) maitiro ekufambisa anoshanda nekugamuchira zviratidzo kubva kuma satellites, uye izvozvo hazvibviri pasina rumwe rutivi rwetena.Nokuti iwe kazhinji hauoni chero chiratidzo cheantenna paunotarisa chechina che GPS kubva kwavari ane antennas angave akavanzwa mukati, kana akavakirwa mukati, iyo nyaya.
Mukuwedzera kune akavakwa-muintenas, mazhinji majezvi eG GPS anewo sarudzo yekushandisa antenna yekunze. Kunyange zvazvo kazhinji isingafaniri kuisa imwe kunze GPS antenna, pane zviitiko zvingabatsira.
Ndiani Anoda GPS Antenna?
Kana iwe wakanga uchishandisa GPS unit kwenguva yakati, uye iwe hauna kumbocherechedza chero kurashikirwa kwemashoko kana nyaya dzakarurama, saka iwe haufaniri kutoda chero rudzi rwekunze antenna. Iyo chete yega yega kana iwe unoronga pakutya kune imwe nzvimbo iwe usati wambove uripo, panguva iyo mamiriro ezvinhu akasiyana munzvimbo itsva angaita kuti antenna inofanirwa.
Kana, kune rumwe rutivi, wakamboona nharo dzakadai sokurasikirwa kwechiratidzo kana kusakarurama kwakanaka ne GPS, saka mikana yakanaka kwazvo kuti imwe kunze GPS antenna inogona kukosha mutengo wekutenga.
Zvinonyatsoitika kune zvinhu zviviri: unhu hwenyena yekunze iyo GPS yako yomuviri yakauya nayo uye zvipingamupinyi zvakananga zvauri kuita.
Zvimwe zvinogona kuitika zvinosanganisira kushandura kubva pane imwe girasi yeGP unit kuenda kune-in-dash unit , kana kutenga chigadzirwa cheGPS chitsva kwekutanga. Mune mamiriro ezvinhu akadai, inogona kubhadhara kubvunza zvakapoteredza kana munhu ari munzvimbo yacho ave ane chiratidzo kana kuti yakarurama nenyaya dze GPS dzisati dzaita hupfumi.
Migumisiro yezvinodiwa uye kushamwaridzana paIndaneti Kugamuchira
GPS navigation devices inoshanda kuburikidza nokugamuchira zviratidzo kubva kune network ye satellites iyo chikamu cheGlobal Positioning System. Nokutora nhungamiro uye kuratidza simba rema satellite akawanda mukufunga, iyo GPS inokwanisa kukanganisa kuverenga nzvimbo yayo yepanyama nechepakati shoma shoma.
Apo imwe GPS inenge isina kujeka kwechidenga nekuda kwekudzivirira, inogona kunge isingakwanisi kuwana zvakakwana zviratidzo zveSatellite, izvo zvingaguma kana kusakundikana kwekushanda kana kukanganisa kwakarurama. Izvi zvinogona kukonzerwa nezvinhu zvakadai sezvivako zvirefu, asi matenga (uye kazhinji mawindo) emotokari uye matori anoitawo kuvhiringidza kunogona kuderedza simba re signal re GPS.
Migumisiro yekudzivirirwa inogona kugadziriswa nekuisa nzvimbo yeGPS muhwindo, asi dzimwe motokari dzakaoma kubata nadzo kupfuura vamwe. Semuenzaniso, denga remapuranga rinogadzira zvakawanda zveRF nhoo kupfuura ragtops, uye mahwindo akapfigirwa anogona kusanganisira tinyoro twiduku twese inogona kudzivirira chiratidzo cheGPS.
Internal Vs. External GPS Antennas
Nzira dzakawanda dzekufamba GPS dzinoenda dzinouya nekunze kweantennas dzinoshanda zvakanaka kana dzichiratidza zvakajeka, unobstructed view of the sky.
Zvisinei, idzi antenna dzomukati hadzisi zvishoma kudarika zvinyorwa zvakakura zvekunze, izvo zvinogona kunge zvisingatauri kana kuwedzera. Muchiitiko chekusimudzirwa kwekunze kwemainete, simba remasimba re GPS rinogona kunge rinopetwa kaviri zvichienderana neinternet antenna.
Kana iwe ukaona kuti yako GPS unit dzimwe nguva inokundikana kuwana chiratidzo, kana kana ichiita seisina kururama pane dzimwe nguva, ipapo antenna yekunze inowanzogadzirisa dambudziko. Zvinodhura uye zviri nyore kuedza kuendesa chikwata chakakomberedza mumotokari yako kutanga, sezvo izvozvo zvingabatsira kuderedza kusagadzikana uye kukanganiswa kwezvinhu, asi unogona kuwana kuti mhinduro yakakwana ndeyokuisa antenna yakasimbiswa kunze.
Passive Vs. Amplified GPS Antennas
Kunze kwema GPS antennas inogona kunge isina kuwedzera kana kuwedzera. Antennas passive anongogamuchira chiratidzo cheGPS uye achiendesa kune imwe yegomba rekufamba GPS, asi masangano anoshanda anosanganisira amplifier powered iyo inosimudzira simba rechiratidzo.
Iyo yekupedzisira inowedzera inodhura uye yakaoma kuisa, asi inogonawo kuiswa mberi kure ne GPS yako unhu pane yekuti antenna isingaiti. Muzviitiko zvakawanda, antenna yekunaka inofanira kuiswa isina kupfuura mamita matatu ecoaxial cable pakati payo ne GPS.
Sezvo antennas anoshanda anogona kuiswa zvakanyanya kure, ivo vari nani zvakakodzera kushandiswa nemagetsi makuru.
