项目摘要

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.

本提案的目标是实现GEOHALO的使命。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、惯性导航系统和激光高度计。GEOHALO使命应证明HALO上的这一仪器的可行性和性能，以实现位场量的空中测量（重力测量和磁力测量）、GNSS直接和间接（反射）测量以及激光测距。不同技术的性能必须在飞行条件下得到证明，这将与迄今为止通常用于航空电子物理学的（较小）飞机的性能有很大不同。利用HALO的远程能力，GEOHALO的使命将在测量飞行的三天内覆盖感兴趣的扩展区域。总的来说，拟议的项目追求一个全新的应用程序的大地测量地球物理仪器工作在一个移动的平台，如光环。通过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层带，并改善重力场和磁场，这对岩石圈结构和板块运动学的研究提供了重要的制约。
