Key outputs of the project will be to fly packaged Wee-g (MEMS gravimeter) and Wee-grad (MEMS gradiometer) on a fixed wing drone platform, together with integrated vibration isolation for enhanced reduction from inertial accelerations. Using the data from field trials in the 1st year of the studentship, we will further enhance the isolation performance and target 1milliGal (10-5 m/s2) sensitivity (required level of acceleration sensitivity for both oil & gas and mineral surveying) during year 2. A second set of field trials, together with inversion of the datasets with BP, will form the 2nd and 3rd years of the studentship respectively. Demonstrating milliGal acceleration sensitivity will make a significant and transformative step in autonomous surveying, which currently requires large heavy instrumentation to be flown on piloted aircraft. There are significant follow-on opportunities to pursue in the oil & gas and mineral prospecting sectors.

该项目的主要成果将是在固定翼无人机平台上飞行封装的Wee-g（MEMS重力仪）和Wee-grad（MEMS梯度仪），以及集成的振动隔离，以增强惯性加速度的降低。利用第一年的现场试验数据，我们将进一步提高隔离性能，并在第二年实现1 milliGal（10-5 m/s2）灵敏度（石油和天然气以及矿产勘探所需的加速度灵敏度水平）。第二组现场试验，以及BP数据集的反演，将分别形成学生的第二年和第三年。演示毫伽加速度灵敏度将使自主测量迈出重要的变革性一步，目前需要在有人驾驶的飞机上飞行大型重型仪器。在石油和天然气以及矿产勘探领域有重要的后续机会。
