59 -- WIRELESS POP-UP TARGET TELEMETRY SYSTEM SOL n/a DUE 071798 POC Neal Ware, US ARL, AMSRL-HR-SF, Bldg 459, APG, MD 21005-5425, 410-278-5428/5845 The Army Research Laboratory (ARL) has a requirement for a state-of-the-art telemetry system for its portable pop-up target system. This system shall be a digital, wireless, portable, short range communications system that provides a command and data evaluation link between ARL's existing pop-up targets and the range control personal computer. It is envisioned the system would consist of an RF transmitter/receiver connected to a personal computer capable of sending and receiving commands/status to a pop-up target. At the target, circuitry would need to be developed to receive RF data from the control receiver/transmitter, respond to commands, obtain target status from on-board analog/digital I/O channels, time-tag target events (10 ms resolution), and transmit back appropriate time-tagged information to the control point. The range control personal computer can present programmed arrays of targets at any distance, time interval, and sequence. The computer system has a software package that records and reduces range events, such as targets presented, target time, target hits, shots fired, and time of shot. Specific requirements of this system are as follows: The effective range of communications between the control-point computer and the pop-up targets shall be no more than 2000 meters. The telemetry system must contain a minimum of four digital I/O channels and three analog I/O channels. Digital output channels must be able to operate in the range of 3-32 volts DC which is required to operate a DC solid state relay used to raise and lower a target. Digital input is TTL logic. Analog input capability must be in the range of 0 to +10 volts DC with 8-bit resolution. The analog circuitry must detect a 20 microsecond pulse as generated by a bullet passing through the target silhouette, and must periodically monitor the steady-state DC voltage applied to the metallic silhouette to verify proper hit detection performance of the silhouette. The system must be low-powered, DC operated, for extended unattended battery-powered operation. The system must contain on-board software capable of responding to commands from the control-point computer such as target up, target down, get target position, or get silhouette voltage. The target unit must also be capable of autonomously responding to the 20 microsecond analog pulse without control computer intervention. Initially, the system must accommodate one shooter, and up to 24 pop-up targets configured as one firing lane. Estimated value range is $50,000. to $75,000.00. All information shall be sent to POC above, Neal Ware. Posted 06/25/98 (0176)
