Trimble’s Lassen® iQ module is one smart buy. It adds powerful, 12-channel GPS functionality to your mobile product in a postage-stamp-sized footprint with ultra-low power consumption and extreme reliability—all at a very economical price.
Designed for portable handheld, battery-powered applications such as cell phones, pagers, PDAs, digital cameras, and many others, the module is also ideal for standard GPS applications such as tracking.
The 12-channel Lassen iQ module is fully compatible with Trimble’s popular Lassen SQ module. Using Trimble’s breakthrough, patented FirstGPS® architecture, the module delivers complete position, velocity and time (PVT) solutions for use in the host application.
Powerful Performance The Lassen iQ module features two GPS signal sensitivity modes: Standard and Enhanced. With Enhanced mode enabled, the module automatically switches to higher sensitivity when satellite signals are weak.
The module also supports TSIP download of critical startup information for fast acquisition. This aided GPS (A-GPS) startup provides hot start performance for each power-up.
The Lassen iQ module is the only stamp-sized GPS product that supports the four most popular protocols: DGPS (RTCM), TSIP (Trimble Standard Interface Protocol), TAIP (Trimble ASCII Interface Protocol) and NMEA 0183.
The Lassen iQ module combines Trimble performance and quality with low cost. With an MTBF (mean time between failures) figure of 60 years, it is one of the most reliable GPS receivers on the market.
Hardware A metal shield encloses the module for protection and ease of handling. The package has a small form factor, (approximately 26 mm x 26 mm, including the shield). It typically requires less than 90 mW of power at 3.3 VDC.
The highly integrated module is a miniature board containing Trimble GPS hardware core based on our Colossus® RF ASIC and IO-TS digital signal processor (DSP), a 32-bit RISC CPU and fl ash memory.
Antennas The Lassen iQ 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; see the reverse side for antenna details.
The module provides both antenna open and short detection plus antenna short protection.
The Lassen iQ Starter Kit provides everything you need to get started integrating state-ofthe-art GPS capability into your application.
