Product Overview
The AT-1110-GKBD is a complete GPS and BeiDou navigation engine module featuring ultra-high sensitivity, ultra-low power consumption, and compact design. Built on the high-performance GK9501-BGA chipset, this module supports BeiDou-3 satellites and provides five key functions: real-time navigation, fast positioning, precise timing, position reporting, and short message communication services. With exceptional -165dBm tracking sensitivity, it extends positioning coverage to urban canyons and dense foliage areas where traditional GPS modules struggle. The compact 11×10×2.2mm size and ultra-low power consumption make it ideal for integration into portable devices and space-constrained applications.
