military use with 1° RMS accuracy on each axis and a 50 Hz update rate. The unit is
supplied with a durable aluminium housing and comprehensive test software. Data
from three silicon magnetometers and three MEMS accelerometers are combined to
provide highly accurate heading, pitch and roll data. The World Magnetic Model is
also incorporated enabling the module to automatically provide global heading
referenced to north and detection of magnetic anomalies. Although the high
specifications and range of features make these modules the preferred solution, the
high US$795 cost of the unit exceeds the project budget and therefore cannot be used.
