SKG122GR is a high-performance, dual-band and multi-system navigation, supporting the new generation of Beidou-3 signal system. The module can support satellite receiving modules of GPS, Beidou, GALILEO, QZSS and SBAS at the same time. L1+L5 dual-band positioning enables positioning with high sensitivity, high precision, and more reliable product performance.
The module integrates the internal RTK algorithm and implements centimeter-level positioning with RTK service. Modules can be configured to become mobile stations. To meet the strict requirements of professional positioning and personal consumption needs.
The module is compact in shape, compatible with the international mainstream navigation and positioning modules in the market, using SMD pad, support standard take and put and reflow welding.
