The SKG16A is a complete GPS engine module that features super sensitivity, ultra low power and small form factor. The GPS signal is applied to the antenna input of the module, and a 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 MediaTek MT3339 single-chip architecture, Its –165dBm tracking sensitivity extends positioning coverage into place like urban canyons and dense foliage environment where the GPS 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.
