Abstract

Remote monitoring of the munition assets is directed to providing a munitions monitoring system and method for monitoring the environment approximate to a munition and transferring data of the environment to a location remote from the munition for storage or processing. A local monitoring device communicates directly with a remote device at a location remote from the munition, the monitoring device being proximate to a munition with a plurality of sensors that monitor the environment of the munition. The local monitoring device can communicate directly with a centralized relay system that is located in the general proximity to a munitions stock pile and/or with a mobile remote device, such as mounted on a vehicle or a hand-held device. The data can be correlated with the operability of the munition.
