Introduction

Trimble's Lassen LP GPS is a low power miniature GPS receiver module that is ideal for power-conscious portable applications. It is intended specifically for system designers and integrators
who are developing the next generation of portable devices. This embedded technology gives the
system developer the programming flexibility to achieve a significant reduction in power consumption.

Power management

The Lassen LP GPS features a new set of power management tools that puts the power budget decision
in the developer's hands. The developer now can determine the best balance between operational
frequency and power conservation for a particular application. In Schedule Track operating mode, the developer can program the unit to power up, quickly acquire satellites and output position to a schedule. After gathering satellite data and computing its location, the receiver may be directed to power down to a minimal mode of operation for a programmed interval or until awakened by a hardware interruption.

Ease of integration

Lassen LP GPS provides a choice of data protocols for maximum flexibility. The TSIP binary data protocol incorporates new power management features and provides maximum control over system operation. The TAIP and NMEA protocols are available where ASCII data is preferred. A secondary serial input port is available for RTCM SC-104 differential correction data for high accuracy applications.

The Lassen LP GPS also incorporates Trimble's antenna detection and protection circuit to monitor the condition of the antenna system. And high performance, miniature 3.3 V antennas are available for the Lassen LP GPS.

Getting Started

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