| Research Abstract |
An experiment of geomagnetic vector absolute measurements using star constellation pattern has been conducted. To measure the geomagnetic field, an one-axis fluxgate magnetometer was developed and used.
The first experiment is to use star constellation pattern with sensitive video camera. This type of absolute measurement is available only on the clear day on the ground, and not applicable for the place where sky is not clear such as deep sea application.
We investigated the method to calculate the direction from star constellation pattern. However, the mechanism to rotate the sensor and star camera was difficult to complete and left as a future work.
