Abstract: The control and telemeter device of towed target is designed based on COTS to meet the requirements of multi-function, high quality, small mess, small scale, low-power and low cost. Its hardware platform is constructed on the base of PC/104 and the unit of CPU, I/O, GPS, data transceiver, and power supply are typeselected. The function of instruction collection and display, instruction fault tolerance, real-time large quantity data receiving and saving and data download and program install are realized on the base of commercial DOS operating system. The ISR and multi-grade-buffer are used to make the system work properly. The experiments show that the system functions perfectly and it meets the design and appliance requirements of the control and telemeter device of towed target.
