SKG178T is a GNSS multi-system high-precision timing module. Based on multi-system, low-power, high-performance SoC chip design. It supports systems such as BDS, GPS, GLONASS and Galileo, and can receive and process two or three of these systems at the same time, or a single system can work independently.
SKG178T supports SBAS, QZSS system and DGNSS data input function, has advanced AGNSS function, and can improve the positioning speed through the auxiliary data service of and CoreStar in the case of networking.
The SKG178T module integrates filters, linear amplifiers and antenna protection functions, and has optimized RF structure and interference suppression capabilities, ensuring that the module can still provide good performance in complex electromagnetic environments.
The SKG178T module supports fixed-point timing, optimized position timing, positioning timing, and can ensure good timing accuracy in complex signal environments.
The SKG178T has a compact form factor and uses SMT pads to support standard pick-and-place and reflow soldering. Fully automated integration, especially suitable for low-cost, low-power applications.
