Abacus supports major ground system projects with a variety of capabilities in C4ISR, air defense systems and operations stations.  Our work encompasses problem definition, requirements analysis, simulation, system development, and system integration and test.

Abacus has participated in creating command, control, communication and intelligence systems for the Army's major Future Combat Systems (FCS) project and such large-scale systems as the U.S. Navy DD(X) ships, the U.S. Navy LHA ships, the Joint Surveillance System (JSS) and the Tracking Data Relay Satellite System (TDRSS).  Our involvement also includes development of major systems consisting of hierarchical networks of computers using a network-centric paradigm.

We develop tactical system applications for a variety of operational enviornments and performance requirements such as those we contributed to the U.S. Army Future Combat Systems (FCS) initiative, the TACFIRE system, and the AN/TSQ-73 Missile Minder System.

Abacus is participating in the test and integration phases of several major systems, and our expertise extends to test requirements, procedures, implementation and evaluation.  We have developed and used special tools and techniques on a multitude of major projects including the U.S. Space Shuttle, the International Space Station, the Advanced Launch System (ALS), the Iridium satellite telecommunications system, the Spaceway broadband communications system, the Ground-based Midcourse Defense (GMD) System the FAB-T broadband communications system, the C-17 aircraft, the B1B stealth aircraft, the U.S. Army Future Combat Systems (FCS) initiative, the Joint Tactical Radio System (JTRS), the National Aerospace Plane (NASP), and the Virtual At Sea Training (VAST) system for the Navy.

We model and simulate engineering systems to ensure a thorough analysis and evaluation of critical system factors.  Our work involves performance evaluation, sensitivity analysis, and hardware simulation.  Shown below is a major simulation capability developed for the FCS initiative.
