Trimble's new Lassen™ SQ module adds complete GPS functionality to your mobile product in a postage-stamp-sized footprint with ultra-low power consumption. The module is designed for portable handheld, battery-powered applications such as cell phones, pagers, PDAs, digital cameras, and many others.
Using Trimble's breakthrough FirstGPS™ architecture, the module delivers complete position, velocity and time (PVT) solutions for use in the host application. The Lassen SQ module uses minimal power and space and delivers a robust, reliable PVT solution.
Lassen SQ is the only stamp-sized GPS product with the two most popular standard protocols: TSIP (Trimble Standard Interface Protocol) and NMEA 0183. The module is enclosed within a metal shield for ease of handling. The shield acts as a protective case.
