Spacemag & Spacemag-Lite Three Axis Magnetometer Bartington Spacemag & Spacemag-Lite Three-Axis Magnetometers Bartington Defence & Space offers two fluxgate magnetometers for spaceflight applications.

For ground testing, we provide units built with standard components to reduce the cost to our users with cleanroom assembly available as an option.

This makes Spacemag-Lite suitable for both commercial and scientific missions, where cost is a consideration.

2 Spacemag & Spacemag-Lite Three Axis Magnetometer Bartington Spacemag & Spacemag-Lite Three-Axis Magnetometers Bartington Defence & Space offers two fluxgate magnetometers for spaceflight applications. Spacemag is designed for long term and interplanetary space missions and can be supplied with 150kRad radiation hardened components and ISO 7 assembly. For ground testing, we provide units built with standard components to reduce the cost to our users with cleanroom assembly available as an option. Spacemag-Lite, ideal for a variety of low Earth orbit (LEO) missions, has been designed to tolerate up to 50kRad of radiation exposure whilst using commercial off the shelf (COTS) components. This makes Spacemag-Lite suitable for both commercial and scientific missions, where cost is a consideration. The standard sensor is designed for CubeSat integration, though other configurations are also available depending on the mission requirement.
