Deployment Sequencer Electronics (DSE)

Deployment Sequencer Electronics (DSE)

Integrated Solution for  Deployment of Secondary Rideshare Payloads

The Deployment Subsystem Electronics (DSE) component is configurable for up to 6 channels of deployment switching and monitoring. The unit is compatible with PnP standards as well as traditional communication interfaces. The DSE switches deploy spacecraft bus components or payloads via opto-isolated control.

Scalable, extensible architecture – supports variety of deployment mechanisms
Up to 6 deployment channels – each channel provides up to 5A for deployment
6U  form factor
Local embedded controller logic provides ability to

  • program deployment sequence and time interval between successive deployments
  • Initiate an auto deployment sequence after a programmable mission elapsed time
Modular interface card can be selected for Spacewire or RS-422 communications
Two design configurations

  • Short duration
  • Long duration / high reliability
