AstraNav

Astra Navigation is the creator of M-GPS™, the magnetic-based global positioning system that works everywhere on Earth. Inspired by navigation systems used in nature, M-GPS harnesses the Earth's magnetic field to provide hyper-precise, secure location information in the air, on the ground, underground and underwater, regardless of environmental conditions. Astra Navigation was founded by a team of experts from NASA, Intel, Caltech and the US Department of Defense who are committed to mapping the world with magnetism and providing continuous, reliable navigation anywhere in the world and wherever satellites, beacons and other traditional GPS systems can't go.
