GPS-kanyanga: tsananguro, chinangwa, unhu

GPS-kanyanga - ichi ndechimwe chezvinhu zvinokosha zvenyaya Wireless kwezvivako. Kubva chisarudzo chakarurama uye zvakarurama nokushanda vakati mano vanovimba chokupika yose ino, sezvo ivo kuona kunonyanyisa siyana mano, bandwidth migero yokukurukurirana uye etc.

Zvisiri hwavapo GPS-kanyanga mumamiriro ezvinhu akanaka ekunze, anokwanisa kupa zvakanaka akanaka ukama, asi panguva mvura kana rakanaya chando kuchaita kuputsika kana zvikasadaro zvose achamira kushanda. Pasinei ayo pachena nyore, magadzirirwe antennas dzimwe nguva zvinoda zvikuru nesimba uye pfuma kupfuura pakusika kunzwisisa zvemagetsi.

Kupatsanura pakati GPS-kanyanga iri hupfupi. Ivo:

• vanoshingaira uye pusa;
• mudziyo kwokunze uye mountable charge (hunowedzera mhando).

Nhasi inopa guru vakasarudzwa madhishi asi musakanganwa kuti pasinei yakachengeteka uye simba chingava mudziyo kana rinoshandiswa pamwe yakaderera unhu GPS-kanyanga, ari hwokugadzira zvechadenga ezvinhu vari kure avo yakati. Basa mudziyo yakadaro haazogumisi akatarisirwa mugumisiro kuna user.

Active GPS-kanyanga mwero pusa muenzaniso pamwe pakuvara gudzazwi. Kwakadaro mano zvinoshandiswa GPS-vagamuchiri, umo kusina dzakawanda mano, kana iri dzimba goho connector nokuda kwokunze kanyanga. Active mano vari vachipfuma utetsa pusa zviitiko, kuwedzera nhamba chiratidzo pamwero kuti ruzha pamwero, kuderedza matambudziko chero chipi chipingaidzo. Chiratidzo kubva pusa kanyanga iri zvakasimba pachena kuti remagetsi nemwaranzi, uye somugumisiro kusvika mugamuchiri ari akadekara mumugariro uye kunaka. rinoita mudziyo chiratidzo akasiyana amplitude zvikuru kudarika kungogara. By pakusarudza GPS-kanyanga zvinofanira munhu mumwechete, kufungisisa mhando mugamuchiri, nekuti vamwe namano anogona nechekare iine yakavakwa muna kanyanga gudzazwi.

Vagadziri GPS-antennas kupa zvakawanda nechinzwano kwokunze antennas. Ivo zvisingapindirani tichitarisa romugove voltage (3-5V) vane Kuwedzera chiratidzo amplifiers uye bandpass filters, izvo akacheka extraneous anonongedzera kunze aida Frequency siyana. GPS-kanyanga (motokari) inoshanda pane imwe kakawanda 1575,42 ± 3 MHz. Tichifunga bandpass Sefa upamhi akapembera bhendi ndiyo 10 MHz. Avhareji Kukosha kanyanga pfuma 4 db, simba nounzenza 1W. mano kwakadaro vanokwanisa kupa akavimbika kuita ari tembiricha siyana kubva -40 kusvika +100 madhigirii chilis pane hama mwando 100 muzana. Antennas takashongedzerwa nezvirwere akasiyana netambo nezvirwere akasiyana connectors, saka unogona kushandisa navo chero mhando pakugamuchira mano. The waya kureba kunogona kusvika mamita mashanu, nekuti icho yekudyidzana nyore kugadzwa GPS-kanyanga.

Kuti muchidimbu, tinoona kuti ano mano vari optimized maererano siyana dzekuziva kusarudza, zvakadai mukuru dzokusatendeseka, pasi simba rakawanda, mari yakaderera, diki kukura.
