英国宇航公司研制了一种导弹用光纤陀螺,并可能在三、四个月后投入生产.该陀螺没有环形激光陀螺那样精确,但成本低,重量轻,起动快.英国宇航公司估计,这种单轴光纤陀螺的精度为10°/小时,价格可能为1,000英镑.从目前来看,光纤陀螺的市场可能只是对环形激光陀螺市场的补充,但到九十年代,预计光纤陀螺的精度可改善到与激光陀螺直接竞争的程度.英国宇航公司认为,对导弹的中制导来说,现有的精度已经足够了.
British Aerospace has developed a guided-flight optical fiber gyro that may be put into production in three to four months. The gyroscope is less precise than a ring laser gyro, but low cost, light weight, and fast starting. Aerospace estimates that this The accuracy of a single-axis fiber optic gyroscope is 10 ° / hour and the price may be £ 1,000. For the time being, the market for fiber optic gyroscopes may only supplement the market for ring laser gyroscopes, but by the 1990s the accuracy of fiber optic gyroscopes is expected to improve To the level of direct competition with the laser gyro, which BAE believes currently has enough accuracy for the guidance of missiles.
