1.4. IS-900 SimTracker & VETracker Processor
The IS-900 Processor uses specialized firmware running on a dedicated processor to control
motion sensor data acquisition and then calculate tracking and related data for output over serial
or Ethernet interfaces. Shown in Figure 2, the SimTracker Processor has five front panel LEDs
which indicate active ports during normal operation. Shown in Figure 3, the VETracker
Processor has eight front panel LEDs to indicate active ports. Both processor configurations
have a front panel LCD display and selection buttons for checking and changing tracking system
parameters. The tracking devices, SoniStrip, host computer, and power connectors are accessed
from the rear panel (described in detail in Section 3).

1.5. SoniStrips, SoniFrame SoniWing Constellation™ &
SoniPods acoustic pulse transmitters
The SoniStrips (Figure 4), SoniWing (Figure 5), SoniFrame (Figure 6) and SoniPods (Figure 7)
have ultrasonic SoniDisc transmitters that receive addressed signals from the Base Processor
Unit and transmit ultrasonic pulses in response. The acoustic transmission beam width for each
SoniDisc is adjusted for wide-angle coverage (approx. 70-degree cone angle) to maximize the
tracking area.
