Umwe mu bantu bagize uruhare runini muri uwo mushinga ni Roger L. Easton, umuhanga w'Umunyamerika wafashije kubaka urufatiro rwa GPS ikoreshwa ku Isi yose.
Roger Lee Easton yavukiye muri Leta Zunze Ubumwe za Amerika mu 1921. Nyuma yo kwiga ubugenge n'ubwubatsi, yatangiye gukora muri United States Naval Research Laboratory (NRL), ikigo cyakorerwagamo ubushakashatsi ku ikoranabuhanga rya gisirikare n'iry'ikirere.
Mu myaka ya 1950 na 1960, isi yari itaratangira gukoresha internet. Mudasobwa zari nke cyane, telefoni zigendanwa ntizari zabaho, ndetse no kohereza ubutumwa hagati ya mudasobwa byari bikiri mu ntangiriro.
Icyo gihe Easton yatangiye gukora ubushakashatsi ku buryo satellites ziri mu kirere zashobora kohereza ibimenyetso by'igihe nyacyo (precise timing signals). Igitekerezo cye cyari uko umuntu wese ufite igikoresho gishobora kwakira ibyo bimenyetso yashobora kumenya aho aherereye ku Isi.
Mu 1973, Leta ya Amerika yatangije ku mugaragaro umushinga wa Global Positioning System (GPS), uhuza ibikorwa byakozwe n'abahanga batandukanye. Roger Easton yabaye umwe mu bantu b'ingenzi mu gutegura uburyo satellites zizatanga amakuru y'igihe n'aho ziherereye, ari bwo bushingiyeho GPS ikoreshwa n'ubu.
GPS yatangiye ikoreshwa cyane mu gisirikare. Nyuma y'aho, mu myaka ya 1980 na 1990, yatangiye gufungurirwa n'abaturage basanzwe. Uyu munsi, GPS ikoreshwa muri telefoni zigendanwa, indege, amato, imodoka, ubuhinzi bugezweho ndetse no mu bikorwa by'ubutabazi.
Icy'ingenzi ni uko GPS idakenera internet kugira ngo ikwereke aho uri. Yakira ibimenyetso bituruka kuri satellites zizenguruka Isi, internet ikaza gusa gufasha mu gukuramo amakarita cyangwa amakuru y'inyongera.
Kubera uruhare rwe muri iri koranabuhanga, Roger L. Easton yahawe ibihembo byinshi, harimo National Medal of Technology and Innovation, kimwe mu bihembo bikomeye bitangwa na Leta ya Amerika ku bahanga mu ikoranabuhanga.
Amateka ya Roger L. Easton agaragaza ko bimwe mu bikorwa by'ikoranabuhanga dukoresha buri munsi byatangiye gutekerezwa kera cyane, mbere y'uko internet ibaho. Uruhare rwe mu kubaka GPS rwahinduye uburyo isi ikora ingendo, ubwikorezi n'itumanaho, bituma uyu munsi umuntu ashobora kumenya aho aherereye mu masegonda make aho ari hose ku Isi.
