A Divert Attitude Control System is a quick reaction propulsion system providing control over positions of missiles, satellites, and spacecraft. Regarding missiles, whether a ballistic measure, counter measure or defensive measure, DACS allows for interception of its target with greater accuracy and reliability.

Needing a Divert Attitude Control System?

We would love to hear about your program and how we may help.



Attitude control using small, solid propellant thrusters is a proven technology in several systems. Our DACS uses a thruster technology specially developed for rapid response and precision control and includes an electronic control architecture uniquely suited to short flights and precision timing. The system consists of a Smart Bus Controller (SBC), a network firing bus, smart initiators, rocket motors, and a retention structure. The SBC is the command interface between the vehicle, with the SBC over a high speed link or may be embedded in the vehicle control electronics. The SBC permits firing of devices or rocket motors in any sequence, including simultaneous or batch firing and sequential firing. If different thruster impulses are present, the system can identify and selectively control them as well.


Our foray into pyrotechnic initiation control dates back to the development of airbag systems in automobiles. Since that time, along with further development, we have supplied high performance thrusters used on a wide array of systems for controlling vital maneuvers on programs such as Compact Kinetic Energy Missile (CKEV), Kinetic Energy Active Protection System (KEAPS), Mars Lander Program, Precision Guided Mortar Munitions (PGMM), Short Range Countermeasure (SRCM) and Long Range Countermeasure (LRCM).
