Trimble's 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.

Overview

The highly integrated module is a miniature board containing a GPS hardware core based on Trimble's Colossus™ RF ASIC and IO-TS digital signal processor (DSP) design and a 32-bit RISC CPU. The module offers onboard data storage in flash memory for complete processing capability.
