The SKM80D 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 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 MT3333 single-chip architecture, Its –165dBm tracking sensitivity extends positioning coverage into place like urban canyons and dense foliage environment where the GNSS was not possible before.
