A sequence is an ordered list of commands, each tagged with a time. An absolute tag is measured from the start of the pass. A relative tag is measured from the previous command. A wait-for-telemetry step holds the sequence until a sample says it is safe to continue.
Power the payload without keying the transmitter into a dead radio. Enable the converter at absolute T+0, wait until the bus reads at least 28 V, turn the payload on at relative +5 s, then the transmitter at relative +2 s.
