The Gotop GT-2217-SF 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 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.
Its –159dBm 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.
