information in forests and under trees. Signals less than 10 percent of the origi-

nal strength can be detected using SiRFstar technology.

TricklePower™ mode reduces the GPS receiver’s power consumption from

more than 1 watt to less than 150 milliwatts (mW) for continuous position up-

date applications.

Push-to-Fix™ mode reduces average power consumption to less than 15 mW

for on-demand position applications - power consumption even cell phones can

live with.

To enhance the quality of the position-

ing data, a Dead Reckoning technique is

added. A solid state Gyro (Piezo tech-

nique) provide direction information.

An odometer or preferred a solid state

accelerometer to provide distance in-

formation. The accelerometer also pro-

vides tilt information to be used in

compensating the Gyro output.

Panasonic EWTS4 Compact Angular Rate Sensor

This angular rate sensor utilises Coriolis force generated by a vibrating tuning fork.

This sensor consists of sensing and driving elements, tuning fork driving circuit

and the signal processing circuit. The tuning fork is composed of two metal pieces,

a connecting block and four piezo-electric elements. A compact and reliable angu-

lar rate sensor has been realised.

Operating Temperature Range -30 to +80

Supply Voltage Range 5±0.25 V

Zero Point Voltage 2.5±0.4 V

Sensitivity 25 mV/deg/s

Output Voltage Range 0.3 to 4.7 V

Output Noise < 10 m Vp-p
