About
The Deployment Sequencer BU-12 is a crucial component for space missions, designed to manage the deployment of satellites. Upon receiving an activation signal from the launch vehicle, it initiates a pre-programmed mission cyclogram. This sequencer then provides targeted output signals to trigger the deployment mechanisms for each satellite. In addition to controlling deployment, the BU-12 also transmits telemetry information back to the launch vehicle, confirming the successful actuation of the mechanisms and the deployment of the satellites. This ensures reliable and verifiable satellite release during orbital insertion.
