Introduction

The Lassen™ SK-II GPS module is a member of Trimble’s renowned Lassen line of OEM GPS products for embedded applications.

 

The Lassen SK-II module builds on the original Lassen-SK8’s outstanding performance and success in demanding automotive applications. The Lassen SK-II module is intended primarily for OEMs and system integrators who require maximum GPS performance, small size, flexible configuration capability and low power usage.

 

The Lassen SK-II module makes use of the latest advances in silicon technology to offer even more robust RF performance. Tighter integration of the RF front end using trimble’s Colossus™ ASIC has slashed the component count by 25 percent, cutting power consumption to less than 0.5 watts.

 

Top performance Using Trimble’s 8-channel technology, the Lassen SK-II module delivers rapid startup times and reliable performance over the entire – 40° C to +85° C extended temperature range. The module incorporates Trimble’s proven software, which outputs highly accurate position data even in areas where satellite signals are weakened by terrain, foliage and structures. The Lassen SK-II module is also differential GPS (DGPS) ready for applications requiring high levels of accuracy. A full-measurement feature is available for advanced applications.

 

Ease of integration The Lassen SK-II module’s userconfigurable, dual I/O serial ports mean greater flexibility and fast integration. A choice of three data protocols provides the user with maximum configuration capability. Either serial port may be configured to the TSIP (Trimble Standard Interface Protocol) binary data protocol for total control over system operation, to the easy-to-use TAIP (Trimble ASCII Interface Protocol), which is ideal for tracking applications or to output standard NMEA GPS data messages. The receiver is delivered from the factory with the primary port configured with TSIP In and Out. The secondary port outputs standard NMA-0183 data messages and can receive RTCM SC-104 differential correction data for 2 meter DGPS accuracy.

The Lassen SK-II module also incorporates Trimble’s antenna detection and protection features to monitor the condition of the GPS antenna system.
