Chapter 1 Introduction
TK-1722 is a high-sensitivity GPS receiver module of low cost. With built-in and high-gain LNA
and filter, the GPS engine board of low power consumption and 20 channels is best suitable for
GPS-enabled handheld or AVL applications. Its compact size factor and SMT type pads allow for
automatic assembly and soldering.
TK-1722 is designed to be applied as part of integrated system, which includes but not limited to
PND (Personal Navigation Device), PVT (Position-Velocity-Time) system, GPS-mouse, GPS
Bluetooth Receiver and complex wireless applications such as systems with GSM or GPRS
transmission-enabled tracking devices. The TK-1722 GPS module is the best candidate for
systems that requires stable performance, excellent start-up time, high sensitivity, low power
consumption, positioning accuracy and/or compact size for placement.
