The Naval Air Systems Command (NAVAIR) intends to award a sole source contract to Maritime Surveillance Associates (MSA), under the terms of a Basic Ordering Agreement to perform baseline systems engineering management studies, provide technical support for the design & development of hardware and software updates, and provide improvements to the Global Reconstruction and Measurement Suite (GRAMS). The GRAMS Software provides Maritime Patrol and Reconnaissance Aircraft (MPRA) the ability to extract measured Sound Pressure Level data to the frontline warfighter, as well as the Office of Naval Intelligence. The Post-flight analysis aspects of the software will be utilized to evaluate aircrew performance of the Acoustic Intelligence (ACINT) data collection mission, as well as provide the post flight analysis team a method to extract more data than what was collected on first pass analysis. The software will be capable of providing recommendations for enhanced mission planning for follow on flights deployment of tactical sensors. The software will also be capable of deep dive acoustic analysis for the extraction of ACINT. The GRAMS software upgrades not only provides continued advances in post flight analysis but also provides for in-flight use of measured sound pressure level data for pattern re-evaluation, pattern re-calculation, improved operator performance in detection and classification, post-flight mission reconstruction, and data archiving and dissemination. This software upgrade will be capable of interacting with existing models, equipment, and databased without interference.
