Anti-satellite device design Single Event Effects of
Words in a word error. c. Immediate jump design program, the program should be used to jump immediately to jump because of the number of immediate cure in the PROM,[link widoczny dla zalogowanych], the SEU is not affected, the data in the registers and RAM SEU easily changed. Such measures enable the program to jump and reliable. d. Signs do not have O, l as. Byte 0 and r in a difference of only one, which is equal to 0, only the sub-SEU effects can be considered susceptible to compare with the number, such as 0 to 00H [H said l6 hexadecimal number 1, and l, COH, judgments with 3FH,[link widoczny dla zalogowanych], 3FH is greater than l, less than 3FH 0, so that greatly reduces the probability of a miscarriage of justice caused by SEU. e. CPu prevention program run fly in the program counter and the segment register by SEu effects may make the program run fly. WDT can be found using the program can not continue to run the implementation of flight, by force reset, the program resume operation. For the case of the branch into the illegal procedure,[link widoczny dla zalogowanych], can be found by comparing the results, can be resolved through the reset. In addition, each program module if the immediate establishment of the appropriate number of signs in the legal entry into the module, the pre-set the flag, after entering the match with the immediate and consistent before it is implemented, or can be sentenced for illegal entry, back system management procedures, which are a means to prevent the program from running out. To prevent the program from running out into the RAM data area, destroyed a large area data, the data can be divided into several blocks, the blocks of Q with HLT (HOLD) command isolation. Thus, if program running out into the data area, the meet HLT instruction will stop and wait wDT reset it back by force. Continued on page 9 3 b. 1995, aerospace control Using inertial instrument error compensation to improve accuracy of strategic missiles and other error compensation package must be conducted in order to receive the desired results. 5 Conclusion At present in China has become the inertial instrument to improve the accuracy of strategic missiles, an important factor in improving the precision inertial instrument is still the direction of future efforts. But, after all, inertial instruments to improve the accuracy by the level of technology and other restrictions. So attention to the stability of inertial instruments, the establishment of error models,[link widoczny dla zalogowanych], separation error coefficient, in the instrument or system-level compensation for their error but increase the implementation of the strategic missile hit an important means precision. Foreign experience is worth learning.
