SKG123S is a high-performance, multi system dual frequency navigation and positioning module with SPI interface. The module can simultaneously support satellite receiving modules of GPS, BDS, GLONASS, Galileo, and QZSS. The L1+L5 dual frequency positioning makes positioning faster, with higher accuracy and more reliable product performance.
This module, with its excellent performance, can provide high sensitivity, high precision, and low-cost positioning and navigation solutions for the manufacturing of positioning terminal products such as car mounted and portable handheld devices, meeting the strict requirements of professional positioning and personal consumption needs.
Compact in size, compatible with international mainstream navigation and positioning modules on the market, using SMD pads, supporting standard retrieval and reflow soldering.
