The AGM-158 JASSM (Joint Air-to-Surface Standoff Missile) is a low observable standoff cruise missile developed in the United States. It is a large, stealthy long-range weapon of the 2,000 pounds (910 kg) class. The missile began development in 1995. The JASSM is now entering service in the Common Wealth of Australia as well. An extended range version of the missile, the AGM-158B JASSM-ER (Joint Air-to-Surface Standoff Missile-Extended Range), is under development.
The JASSM was tested with a wide range of aircraft which can carry the weapon, including: the F-16, B-1B, B-2 and B-52. The testing occurred at numerous test range locations to encompass all possible operational scenarios. An instrumentation data link allowed the missile to transmit its health, status and other information in real-time for verification and validation purposes
The EMC FRTSEG group in Irvine, CA was tasked to develop and support a mobile command facility which could receive and process data from the realtime telemetry link. This facility would need to process, record, and display data while also keeping it secure. The facility also needed to provide engineers with the capability to:
- change locations and accommodate a demanding test schedule.
- be able to verify the test item is working properly prior to flight.
- manage parameter information and configuration changes.
- define algorithms for converting the raw PCM data to data which engineer could easily interpret.
- time correlate parameter data with millisecond accuracy.
- provide methods to print and store classified data.
- define custom displays to present the mission critical and test safety data.
- post process data for future analysis and reports.
- have access to onsite support during critical tests.
EMC FTRSEG partnered with a third party to construct a vehicle and install equipment to meet these
challenges. FTRSEG also customized the Instrumentation, Loading, Integration, Analysis and Display (ILIAD) software for unique realtime requirements.
A private network was needed for secure data processing. Six (6) separate Acroamatics / Lumistar
telemetry systems allowed the vehicle to receive and process pulse code modulated (PCM) from multiple sources. A directional antenna was used to receive data from the missile prior to flight. A six foot tracking antenna received data from up to 80 miles away. There were ten (10) different workstations available to visualize data and an additional four (4) Astro-Med strip charts for hard copy plotting. The raw PCM telemetry data could also be recorded in various customer required formats. Engineers could communicate with others involved in the test via the onboard UHF radio system.
