The TCAC system is to be the focal point of Radio Battalion SIGINT operations within the Operations Control and Analysis Center (OCAC) and to be a key segment of the Marine Air-Ground Intelligence System (MAGIS). As such, it must support the OCAC needs for automated information processing and will be the central Radio Battalion SIGINT/EW processing and communications node. TCAC is a land-based system.
The TCAC system currently fielded in the Radio Battalions has many shortfalls. It includes outdated data processing hardware with inadequate processing capability and increasing repair problems. There is no capability to receive direct data input from Radio Battalion collection systems. The TCAC size and weight does not promote either rapid or effective employment. The software originally fielded with the TCAC has no SIGINT analytical tools. Finally, there is no map graphic display. The TCAC PIP will address all of the above shortfalls by providing an integrated mobile sheltered system of state-of-the-art hardware and software.
Current TCAC capabilities do not meet the demanding requirements of the Operations Control and Analysis Center (OCAC) for automated information processing. As more automated and semi-automated SIGINT systems are fielded, such as Mobile Electronic Warfare Support System (MEWSS), Joint Tactical Terminal (JTT), Team Portable Communications Intelligence System (TPCS), it will be increasingly more difficult for the current TCAC to perform its mission. The TCAC PIP will dramatically increase the joint and service interoperability capabilities of the OCAC and other Radio Battalion detachments.The capabilities of TCAC include:
A COEA for the TCAC PIP was completed in February 1993. The study recommended that the existing TCAC system be upgraded by developing and fielding a system similar to the TCAC PIP alternative. Additionally, it suggested that strong consideration be given to consolidating the TCAC PIP and MEF IAS programs. The TCAC PIP COEA considered a variety of options. No models were used for the evaluation of effectiveness for each alternative. Based on the COEA analysis, it was recommended that the current TCAC system should be upgraded by developing and fielding a system similar to the TCAC PIP alternative. The project office determined that the requirement could be best satisfied by designing a nondevelopmental system of COTS, GOTS, and in-service equipment integrated into a shelterized vehicle and utilizing Government developed software. This approach reduced research and development costs normally associated with long term, full scale development. Moreover, by joining with the MEF IAS effort, it was thought that integration, testing, and fielding time would be reduced.
