Unit GPS

SKU:U032

Description

Unit GPS is a satellite positioning Unit. It integrates the COMLOC Beidou navigation chip AT6558 and the signal amplification chip MAX2659, providing high-quality satellite positioning services.

AT6558 is a high-performance navigation chip that supports multiple satellite navigation systems, with 56 channels for receiving satellite signals, receiving GNSS signals from 6 satellite navigation systems simultaneously, and performing integrated positioning, navigation, and timing to obtain accurate global location information. AT6558 can quickly and accurately locate in weak signal conditions such as cities, canyons, under overpasses, and anywhere inside a car. This module is widely used in products such as vehicle monitoring, bus stop reporting, vehicle navigation, ship navigation, and notebook navigation.
