從波音 747 客機(jī)的導(dǎo)航操作、汽車(chē)駕駛每天都會(huì)使用的 GPS 導(dǎo)航系統(tǒng)，到尋寶者要找到深藏于森林某處的寶藏，GPS 技術(shù)已經(jīng)迅速融入于多種應(yīng)用中。 正當(dāng)創(chuàng)新技術(shù)不斷提升 GPS 接收器效能的同時(shí)，相關(guān)的技術(shù)特性亦越來(lái)越完整。時(shí)至今日，軟件甚至可建立 GPS 波形，以精確仿真實(shí)際的訊號(hào)。除此之外，儀器總線(xiàn)技術(shù)亦不斷提升，目前即可透過(guò) PXI 儀控功能，以記錄并播放實(shí)時(shí)的 GPS 訊號(hào)。
