Skylab Ultra high sensitivity  Low Power GPS Antenna Receiver Module Chips SKM61 kids watch gps tracker tractor air conditioner

 

1.Introduction:

The SKM61 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.
It is based on the high performance features of the MediaTek 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.

 

2. Features:

Ultra high sensitivity: -165dBm
Extremely fast TTFF at low signal level
Built in high gain LNA
Low power consumption: Typical 23mA 3.3V
