Dead Reckoning Module (DRM™) 4000
The Dead Reckoning Module (DRM™) 4000 is a miniature, electronic device for personnel on foot that provides the user's position relative to an initialization point. Dead Reckoning (DR) data and external GPS NMEA data are blended by an internal Kalman filter. When GPS data is available, the dead reckoning sensors are automatically calibrated continuously and the two data sources are blended into a composite real-time position data output. When GPS data is unavailable, dead reckoning takes over. DRM™4000 position error characteristics are independent of time, and depend primarily on distance traveled.

HRF-SW1030 Evaluation Board
Honeywell's HRF-SW1030 provides an easy method to evaluate the RF performance of the HRF-SW1030 switch. The HRF-SW1030 is a high performance single pole six throw (SP6T) absorptive RF switch ideal for use in wireless basestation and handset applications that require minimum power and minimum insertion loss.
