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.

Introduction

Trimble's Resolution™ T GPS Timing Receiver is a significant new development in GPS architecture: the general purpose, DSP-based software GPS timing receiver. The development of Trimble DSP/GPS software was key to this accomplishment.

Precise Timing Where You Need It

The receiver is an all-in-view, 12-channel, parallel-tracking, embeddable GPS receiver designed to provide precise GPS or UTC time and synchronization for many static timing applications. The timing accuracy will provide for your current needs with plenty of headroom for future requirements.

This low-cost, yet highly accurate and reliable receiver allows the system integrator to put precise timing and synchronization into locations where cost or size is a limitation. Rather than sharing time from a single timing source, with the resultant delays and loss of accuracy, you now can have precise time (synchronization) at every location regardless of how isolated or remote.

Features Flexibility with Software

To provide a true software driven GPS timing receiver, the Resolution T receiver uses an off-the-shelf, software programmable, general-purpose, digital signal processor (DSP) in place of the usual custom GPS ASIC. Using a general-purpose DSP allows incremental software improvements to be implemented throughout the product life cycle. This is not possible in custom GPS hardware ASICs, because most features are permanently locked in the hardware design. The Resolution T receiver can be updated easily in the field with new features as they become available. The modular design also allows for both reduced integration time and low implementation risk.

1-PPS within 15 ns

The Resolution T receiver outputs a 1 Pulse-per-second (1 PPS) timing signal accurate to within 15 nanoseconds of GPS or UTC (1 sigma) when using an overdetermined solution in a stationary mode.

3 or 5 Volt Antenna Compatible

The receiver is designed for 3.3 VDC prime power, but provides a separate pin on the I/O connector for powering the antenna with a user-supplied voltage from 3.0 to 5.5 VDC.

Starter Kit

The Resolution T Starter Kit provides everything you need to start integrating the module into your application. The kit includes an active, external 5-VDC Bullet-style antenna, 50 feet of RG-59 cable, and an AC/DC power adapter. The starter kit enclosure includes a mother board that provides serial output, and a serial interface cable. A reference manual and monitor programs are provided on CD-ROM.
