SMART TELEMETRY AND RELEASE SYSTEM (STARS™)


The low power, SEA sequencing system is capable of firing hundreds of pyrotechnic devices with microsecond repeatability and sub-millisecond sequencing. It can be used to deploy solar arrays, scientific instruments and many other devices used on satellites and spacecraft.

Smart Energetics Architecture (SEA™) bus-driver chip architecture enables interchangeable, independent multiple bus configurations minimizing Smart Initiator spares required and improving workflow. Additionally, the SEA controller can actuate non-pyro devices such as non-explosive actuators (NEA), motors and various other devices. Our sequencing system includes:

  • Smart Energetics Architecture (SEA™) bus-driver chip enables interchangeable, independent buses minimizing Smart Initiator spares required and improving dispenser and assembly workflow
  • Smart Controller card, a flexible/adaptable command interface between the vehicle and the network bus smart devices. Two may be included should redundancy be desired
  • Permits firing of ordnance devices in any sequence – single, multiple simultaneous or sequential
  • For safety, requires both an analog and digital condition to be met
  • Cyclic Redundancy Code (CRC) also utilized to ensure command integrity and device firing by the intended method only

3 independent inhibits including independent arming line
RS 422 or other standard interface protocols
Tailorable message

STARS allows for the releasing SmallSats and CubeSats in precise orbital slots for perfect mission control. Our sequencer, with SEA bus, prevents inadvertent firing with very high-reliability operation. Each system is fully customizable to fit the specific architecture of the satellite. SEA Buses are distributed symmetrically around the main structure to provide simultaneous commands for balance.

Each system includes:

  • Smart Initiators, NSI -500
  • SEA Controler/Bus
  • HRM and/or separation nuts

Our electronic-pyrotechnic event sequencer is an excellent choice for satellite deployment, satellite subsystems and payload actuation

Arm:

  • Capacitor SEA charge command received – CRC must be correct to recognize the command
  • Enable SEA command received – CRC must be correct
  • SEA Bus – electrical state (“analog condition”) correct
  • Independent Hardware Enable line – Active

Fire:

  • SEA fire command received – CRC must be correct
  • SEA Bus – electrial state (“analog condition”) correct
