Abstract

The invention discloses a measuring and controlling device for aviation superconducting full tensor magnetic gradient based on GPS (Global Positioning System) synchronization. The measuring and controlling device is characterized by being positioned in a pod of a suspension and pod subsystem; the measuring and controlling device for the aviation superconducting full tensor magnetic gradient consists of an SQUID (Superconducting Quantum Interference Device) reading circuit, a data acquisition and communication module, a flying position and pose information recording module, a working environment monitoring module and a human-machine interface module; other four modules are connected by taking a star topology structure with the data acquisition and communication module as the core. According to the device, after a specific signal at the designated time is resampled by a PPS (Pulses Per Second) frequency doubling sampling clock generated through a digital phase-locked loop based on a GPS time service function, the synchronization of the device and the position and pose information which are given out by a GPS integration navigation is realized by using a time stamp, so that the foundation is laid for inversion by altitude projection; besides, the measuring and controlling device has the characteristics of simplicity for realization, and high extendibility and reliability, and is particularly suitable for being applied under an aviation platform.
