The purpose of this mission was to set up a pair of parallel lines known as a flux gate that scientists can use to study how ice moves out through the Ross Sea.
Works well, but per the STC, can't be installed closer than 24 inches from the flux gate. We have 17 inches in the left wing position.
ASR was carried out in a R-951 furnace using stationary solidification moulds with the square cross-section of 200 x 200 mm with a flux gate. The flux was poured in through a siphon.
The mast-mounted stations contain an internal flux gate compass that aligns wind direction to North.
TorqStar uses a flux gate magnetometer (FGM) strategically placed around the magnetoelastic ring to measure and convert the magnetic force to an electrical signal.
The sensor technology evaluated consisted of a K band Doppler radar to measure distance traveled in combination with a flux gate compass for directional information.
The instrument of choice for measuring magnetic fields between the optimal areas for SQUIDs and Hall probes, or [10.sup.-9] T and [10.sup.-4] T, is the flux gate gaussmeter.
