Precision ±3.9ns
Receiver Type GPS ,BDS,GLONASS
Dimension(L×W×H) 16.2*12.2*2.4(mm)

The SKG121T is a high-performance GNSS all-in-one solution module that features super sensitivity, ultra low-power and small form factor.The RF signal is applied to the antenna input of module, and complete serial data message with position, velocity and time information is presented at the serial interface with NMEA protocol or custom protocol.

It is based on the high-performance features of the STA8089 single-chip architecture, Its -162dBmtrackingsensitivity extends positioning coverage into places like urban canyons and dense foliage environments where the GNSS was not possible before. The small form factor and low power consumption make the module easy to integrate into portable device like PNDs, mobile phones, cameras and vehicle navigation systems.
