Magulu a GPS amagwiritsa ntchito ziwonetsero kuti azindikire malo pa Dziko lapansi
Maofesi a Global Positioning unit amagwiritsa ntchito njira ya masamu ya chiwonongeko kuti adziwe momwe angagwiritsire ntchito, kuthamanga, ndi kukwera. Zipangizo za GPS nthawi zonse zimalandira ndi kufufuza zizindikiro za wailesi kuchokera ku ma satellites angapo a GPS. Amagwiritsira ntchito zizindikiro izi kuti awerengetse mtunda kapena malo omwe ali ndi satana.
Kuwonongedwa Komwe Kumagwira Ntchito
Kutulutsidwa ndiwopambana kwambiri kwa katatu. Deta kuchokera pa satelesi imodzi imasonyeza malo apadera a padziko lapansi. Kuwonjezera deta kuchokera ku satelesi yachiwiri kumachepetsa malo mpaka kudera limene magawo awiri a deta ya satana amafikira. Kuwonjezera deta kuchokera ku satelesi yachitatu imakhala ndi malo abwino, ndipo magulu onse a GPS amafuna ma satellite atatu kuti apange malo abwino. Deta kuchokera ku sateteti yachinayi-kapena ma satellites opitirira anai omwe amamveka bwino ndikumveka kukwera kolondola kapena, pa ndege, pamtunda. Nthawi zambiri GPS amalandirira satellites anayi kapena asanu ndi awiri kapena ochulukitsa panthawi imodzi ndikugwiritsa ntchito katatu kuti awerenge zambiri.
Dipatimenti ya Chitetezo ku United States ili ndi ma satellite satellites 24 omwe amafalitsa dera lonse lapansi. Gulu lanu la GPS lingathe kugwiritsidwa ntchito ndi ma satellite anayi ngakhale mutakhala kuti muli padziko lapansi, ngakhale m'madera amitengo kapena mumzinda waukulu ndi nyumba zazikulu. Aliyense amayendetsa dziko lapansi kawiri pa tsiku, nthawi zonse amatumiza zizindikiro padziko lapansi, pamtunda wa makilomita 12,500. Ma satellites amayendetsa mphamvu za dzuwa ndipo amakhala ndi mabatire osungira.
Mbiri ya GPS
GPS inayamba mu 1978 ndi kukhazikitsidwa kwa yoyamba satetezi. Idalamuliridwa ndikugwiritsidwa ntchito ndi asilikali okha mpaka zaka za m'ma 1980. Zida zonse za ma satellites 24 ogwidwa ndi US analibe mpaka 1994.
Pamene GPS Ilephera
Pamene woyendetsa galimoto akulandira sateleti okwanira satana chifukwa sangathe kufufuza satellites okwanira, kuwonongeka sikulephera. Woyendetsa galimoto amadziwitsa wothandizira m'malo mofotokoza zambiri za malo osayenera. Nthawi zina satellites amalephera kanthawi chifukwa zizindikiro zimayenda pang'onopang'ono chifukwa cha zinthu zomwe ziri mu troposphere ndi ionosphere. Zizindikiro zingathenso kusokoneza zochitika ndi zochitika zina padziko lapansi, zomwe zimachititsa kulakwitsa.
