Modelling solutions to help protect aerospace personnel and assets

aerospace api suite

On-demand access to legacy aerospace modelling software through our open web Application Programming Interfaces (APIs)

earth's atmosphere

Calculate density, temperature and composition of the atmosphere from ground through exosphere, by accessing the NRLMSISE-00 model through a web API.

The information can be used to estimate satellite orbital decay, correct Earth observation data, or as a source term in atmospheric radiation propagation modelling.

Access now

space radiation

Space radiation can damage the critical electronic components of spacecraft leading to mission failure, or damage human DNA leading to long-term health effects such as an increased risk of cancer among astronauts and aircrew.

Estimate cosmic ray intensities and radiation protection quantities in the atmosphere using our API based on the PARMA model.

Access now

global magnetic field

Navigation, GPS, antennae design, mineral exploration, and consumer electronics all require the transformation between the direction of true north and that of magnetic north at the current position.

Calculate magnetic declination and inclination anywhere on or near Earth's surface using our Global Magnet API.

Access now

Our APIs are free for low volume use. See support plans below for high volume use and enterprise integration support.

about us

why the name 'amentum'?

The amentum was a leather strap used by ancient greeks to extend the range and stability of the javelin in flight.

Similarly, Amentum exists to extend the capabilities of its clients and ensure the safety and security of personnel and assets.

radiation modelling services

Amentum Aerospace has a niche capability in modelling ionising radiation environments relevant to defense and aerospace. Contact us to discuss how we can help to explore concepts and derisk techology development projects.
