The growth of this market is largely fuelled by various increasing applications, technological advancements, and the rising aerospace and defence budgets. Furthermore, the growth can be attributed to the increasing demand for accuracy and calibration in guidance, control and targeting, precision-guided armaments and other weaponry. The defence application dominated the market in 2017 and is expected to do the same during the forecast period, with small-diameter missiles, underwater navigators, and unmanned aerial vehicles being the demanding applications and main beneficiaries of high-end MEMS sensors in military applications.
