Introduction

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.

The Lassen SQ module is the only stamp-sized GPS product with
the three most popular standard protocols: TSIP (Trimble Standard
Interface Protocol), TAIP (Trimble ASCII Interface Protocol) and
NMEA 0183. The module is enclosed within a metal shield for ease
of handling. The shield acts as a protective case.

FirstGPS Hardware

The FirstGPS architecture consists primarily of two integrated circuits
and FirstGPS firmware. This technology enables the Lassen SQ to achieve
the unique combination of both ultra-low power usage and micro-size
in the same unit.

Hardware

The Lassen SQ module packages this architecture in a tiny form factor,
(approximately 26 mm x 26 mm, including the metal shield). It typically
requires only 110 mW of power (at 3.3 VDC). Total typical power usage,
including the Trimble 3.3 VDC miniature antenna, is =143 mW. 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.

Antennas

The Lassen SQ module is compatible with active, 3.3 VDC antennas.
Three such antennas are available from Trimble and are recommended
for use according to your application:

  • An ultra-compact embedded
    antenna, approximately the same size as the module itself. This antenna
    is unpackaged, for easy integration into mobile applications.
  • A compact, unpackaged antenna slightly larger than the ultra-compact
    model above.
  • A compact, packaged antenna with magnetic mount
    for flexible, movable installation.

Getting started

The Lassen SQ Starter Kit provides everything you need to get started
integrating state-of-the-art GPS capability into your application.
