摘要： A stabilized field sensor apparatus collects field data, in particular magnetic field data, with reduced motion noise. The apparatus includes a tear drop shaped housing, a tow frame in the housing, a plurality of vibration isolating dampers spaced around the frame, a base assembly mounted to the dampers, a support pedestal having a bottom end fixed to the base assembly and an upper free end, a single spherical air bearing connected to the upper free end of the pedestal, an instrument platform with a lower hollow funnel having an upper inside apex supported on the air bearing for a one point support, principal and secondary gyro stabilizers for maintaining pivotal and rotational stability, and at least one field sensor mounted to the instrument platform for collecting the field data while being stabilized against motion noise including vibration, pivoting and rotation from the base assembly, from the tow frame and from the housing. Stabilization of the instrument platform is enhanced by preserving accurate balance through a dynamic balancing system whereby small masses are moved under computer control to maintain the center of mass of the instrument platform at the center of rotation of the spherical air bearing. The dynamic stabilization process is made more precise by actively vibrating the instrument platform by a set of linear vibrators.

摘要： A pneumatic vibration isolating suspension is disclosed for supporting a payload on a moving carrier while suppressing the transmission of vibrations in the 1 to 50 Hz band between the carrier and the payload. The disclosed invention can be deployed in the air in a towed carrier or sonde, and operated from aircraft power, making it a suitable platform for airborne geophysical instrumentation. It also has particular application to airborne electromagnetic surveying operating in the same frequency band because the sensor vibrations that result in noise created by the modulation of the sensor coupling with the earth's magnetic field are suppressed. Furthermore, the invention can be constructed from resistive composite materials and non-magnetic metals, so it can be operated without producing significant modification to the ambient electromagnetic field being measured.
摘要翻译：公开了一种气动隔振悬架，用于在载体和载荷之间的1至50Hz频带中抑制振动的传播，以支持移动载体上的载荷。所公开的发明可以在拖曳的载体或探空器中的空气中部署，并且从飞机动力操作，使其成为用于空中地球物理仪器的合适的平台。它也具有特定的应用，在相同的频带中进行机载电磁测量，因为传感器振动导致由与地球磁场的传感器耦合的调制而产生的噪声被抑制。此外，本发明可以由电阻复合材料和非磁性金属构成，因此可以在不对所测量的环境电磁场产生显着改变的情况下进行操作。
