1. Khoom piav qhia
F23-U yog Beidou / GPS receiver uas tuaj yeem tau txais satellite signals nrog 72 channels, tsawg zog noj thiab siab rhiab heev, thiab tuaj yeem nrhiav tau sai thiab raug teeb meem tsis muaj zog hauv nroog, hav zoov, thaj chaw siab thiab lwm qhov chaw. Lub receiver tuaj nrog ib tus kws sau ntawv geomagnetic, uas pab tus neeg siv ua ntej ua haujlwm sai dua.
