Information
The CANMOS array consists of 13 fluxgate magnetometers operated by the Geological Survey of Canada, part of
Natural Resources Canada. The heart of the CANMOS is a "bus-clock", a specially-designed plug-in card in the PC that carries a
highly accurate temperature-compensated crystal oscillator, resettable from an external source. A novel feature of the CANMOS design
is the GSC-designed tilt-correcting suspension for the fluxgate triaxial sensors. The CANMOS can be accessed via telephone modem at
speeds up to 14400 baud.
The fluxgate magnetometer samples the magnetic field at 8 Hz. The three component data streams are despiked and filtered using a rectangular
filter over 9 data points, and resampled at 1 Hz. The 1 Hz data are further filtered using a 49 point Gaussian filter, and resampled at intervals
of 5 seconds. The proton magnetometer samples the field at 5 second intervals. The 5 second sampled data form the primary data product available
from the CSSDP.
