Geoscientific Earth Observation with HALO in the Aegean region (GEOHALO)

这项提议的目标是实现GEOHALO任务。为此，Halo应安装一套协调和互补的大地测量-地球物理仪器，包括重力仪、磁力计、全球导航卫星系统天线和接收器、惯导系统和激光高度计。GEOHALO飞行任务应证明该仪器安装在Halo上的可行性和性能，以实现潜在场量的航空测量(重力测量和磁力测量)、全球导航卫星系统直接和间接(反射)测量以及激光距离测量。不同技术的性能必须在飞行条件下得到验证，这将与迄今为止用于空中地球物理的(较小)飞机有很大不同。利用HALO的远程能力，GEOHALO任务将在测量飞行的三天内实现，以覆盖感兴趣的扩展区域。总体而言，拟议的项目追求一种全新的大地测量-地球物理仪器的应用，以便在像Halo这样的移动平台上工作。根据GEOHALO观测，我们将确定爱琴海地区的地球科学量，以便更好地了解希腊俯冲带和北安纳托利亚断裂带，并改善重磁场，这为岩石圈结构和板块运动学的研究提供了重要的约束。

The goal of this proposal is the realization of the GEOHALO mission. For this, HALO shall be installed with a coordinated and complementary suite of geodetic-geophysical instrumentation, including gravity meters, magnetometers, GNSS antennas and receivers, INS, and a laser altimeter. The GEOHALO mission shall demonstrate the feasibility and performance of this instrumentation on board HALO to realize airborne measurements of the potential field quantities (gravimetry and magnetometry), GNSS direct and indirect (reflected) measurements, and laser distance measurements. The performance of the different techniques has to be proven under flight conditions, which will be considerably different to those of (smaller) aircrafts usually utilized for airborne geophysics so far. Utilizing the long-range capability of HALO the GEOHALO mission shall be realized to cover the extended area of interest within three days of measurement flights. Overall, the proposed project pursues a completely novel application of geodetic-geophysical instrumentation to be working on a moving platform such as HALO. From the GEOHALO observations we will determine geoscientific quantities in the Aegean region in order to gain a better understanding of the Hellenic subduction zone and the North-Anatolian fault zone, and to improve the gravity and magnetic fields, which provide important constraints on the investigation of the lithospheric structure and plate kinematics.
