Deliberative and reactive processing are combined to process multi-modal inputs and direct movements and speech of a synthetic character that operates as an interface between a user and a piece of equipment. The synthetic character is constructed as an ally, working with and helping the user learn and operate the equipment. The synthetic character interacts with both a virtual space where the character is displayed, and a physical space (domain) that includes the user. Real-time reactive processing provides lifelike and engaging responses to user queries and conversations. Deliberative processing provides responses to inputs that require more processing time (deep linguistic processing, for example). Knowledge bases are maintained for both dynamic (discourse model, for example) and static (e.g., knowledge about the domain or discourse plans) information types. A rule based system is utilized against the knowledge bases and selected inputs from said user to determine input meanings, and follow a predetermined discourse plan.

The system of claim 4: wherein the transmit chain comprises a plurality of transmit chains; wherein each transmit chain transmits the calibration signal; wherein the frequency dependent calibration vector comprises group delay; and wherein the signal processor determines a frequency dependent transmit calibration vector by comparing the relative phases of the transponder signal at each frequency of the transponder signal as received by each receive chain. 11. The system of claim 10, wherein the calibration signal comprises a plurality of signals, one from each transmit chain, each signal being individually identifiable based on a unique modulation sequence. 12. The system of claim 10 wherein determining a frequency dependent transmit calibration vector comprises comparing a phase difference between two transmit chains for the transponder signal at a first one of the at least two frequencies to a phase difference between the same two transmit chains for the transponder signal at a second one of the at least two frequencies to determine a group delay. 13. The system of claim 12 wherein one of the plurality of transmit chains is selected as a reference chain and the group delay of each transmit chain is defined with respect to the reference chain. 14. The system of claim 1, wherein the radio communication signals are adapted to conform to a code division multiple access standard. 15. A machine-readable medium having stored thereon data representing instructions which, when executed by a machine, cause the machine to perform operations comprising: transmitting radio communications signal to a plurality of other terminals using a transmit chain; receiving radio communications signals from a plurality of other terminals using a receive chain; transmitting a calibration signal through transmit chain to a transponder on at least two different frequency bands; receiving a transponder signal from the transponder, the transponder signal being received on at least two differen
