Product Overview
The AGM-4538-GKBD4P150 is a compact GPS and BeiDou engine module that combines superior sensitivity, ultra-low power consumption, and integrated patch antenna in a smaller gmouse form factor. Built on the high-performance GK9501 chipset, this module features exceptional -165dBm tracking sensitivity that extends positioning coverage into urban canyons and dense foliage environments. The compact 45×38×13mm design with integrated 25×25×4mm patch antenna and pre-attached 150cm 4-pin cable makes it ideal for space-constrained applications. With 66 search channels and 22 synchronous tracking channels, the module delivers reliable navigation data through standard NMEA protocol or custom interfaces, making it perfect for portable navigation devices, vehicle systems, and various location-based applications where space is limited.
