对抗环境下,由于电子干扰、电磁脉冲武器或地形等因素,GPS性能可能降低或失效。目前,洛马公司的弹药专家正在研制一种小型轻便的武器导引头样机,使得在对抗环境下全球定位系统的卫星导航失效时,灵巧弹药也能够昼夜打击移动目标和可重新定位目标。2015年12月17日,洛马公司导弹与火控分部获得美国国防部预先研究计划局(DARPA)价值820万美元的合同,作为DARPA导引头成本转化
Against the environment, GPS performance may degrade or fail due to factors such as electrical interference, electromagnetic pulse weapons or terrain. Currently, Loma’s ammunition specialists are developing a small and lightweight weapon seeker prototype that enables smart ammunition to strike and reposition targets day and night in the event of GPS global satellite navigation failures. On December 17, 2015, Loma’s missile and fire control division received a contract valued at $ 8.2 million from the Defense Advanced Research Projects Agency (DARPA) for cost conversion as a DARPA seeker
