An ultra-low power GPS unit called the Lassen iQ, intended specifically for integrating with other mobile products, has been launched by Trimble, one of the longest-established players in mobile technologies.

The Lassen iQ works in two GPS signal sensitivity modes - standard and enhanced. In enhanced mode, the module automatically switches to higher sensitivity when satellite signals are weak.

The module supports the Trimble Standard Interface Protocol (TSIP) for downloading critical startup information for fast acquisition. This "aided GPS" (A-GPS) startup is said to provide "hot start" performance for each power-up, making it ideal for modern mobile applications.

The device is really small - literally postage-stamp size (around 26mm by 26mm by 6mm), allowing integrators to incorporate GPS functionality in a variety of mobile products. Power requirements are minimal: it needs less than 90 milliwatts at 3.3 VDC.

 

Development kits include the module mounted on an interface board in a durable metal enclosure; magnetic mount antenna; ultra-compact embedded antenna; AC/DC power adapter; serial interface cable; cigarette lighter adapter, reference manual; and GPS toolkit software for communication with the GPS module.
