Magnetometer Laboratory

We are working with PNI RM3100 magneto-inductive magnetometers to develop ground and space-based magnetometer sensors. We are packaging and testing these chip-based sensors to perform in extreme environments on Earth and in Space. We are developing new magnetometer system architectures to enable noise identification in order to simplify ground-based and space-based magnetometry.


New System Architecture

Multi-magnetometers enable characterizing the spacecraft noise

By utilizing extremely low power (5 mW), low mass (5 g) and small size (2.5 x 2.5 x 2 cm) sensors, we can place multiple sensors on the ground or on the spacecraft to be able to sense the natural geomagnetic field and identify any noise sources from the surroundings or satellite. Using a variety of noise identification algorithms, we can remove the noise decreasing the susceptibility to environmental noise (such as cars) around ground sensors and from spacecraft sub-systems. This enables lower fidelity magnetic cleanliness and sub-system magnetic characterization efforts.

The NEMISIS concept uses three magnetometers – a high-quality fluxgate magnetometer on the end of a short boom and two body mounted PNI RM3100 magnetometers. The data from the three sensors can then be used to “clean” the data from spacecraft noise.
