Beschreibungen/Notizen

• This chapter describes approaches for determining absolute position using magnetic field measurements for three different environments: indoors, for ground vehicles, and for aircraft. It provides some background in terms of the nature of Earth's magnetic field. The primary magnetic sources which can be measured in the vicinity of Earth are as follows: Earth's core field, Earth's crustal field, Space weather effects, and Man‐made effects. Magnetic instruments fall into two major categories: scalar instruments and vector instruments. Magnetometer calibration techniques are quite different depending on the type of instrument used and the platform environment. The chapter focuses on determining absolute position by comparing the magnetometer output with a map of the magnetic field (as opposed to orientation‐based uses of a magnetometer, which generally do not determine absolute position).
