5.3.2. Payload Interface Circuitry
Standard interface circuitry passing through the payload-to-launch vehicle electrical connections is shown
in Figure 5.3.2-1. This figure details the interface characteristics for launch vehicle commands, discrete
and analog telemetry, separation loopbacks, pyro initiation, and serial communications interfaces with the
launch vehicle avionics systems.
5.3.3. Payload Battery Charging
Orbital provides the capability for remote controlled charging of payload batteries, using a customer
provided battery charger. This power is routed through the payload umbilical cable. Up to 5.0 amperes
per wire pair can be accommodated. The payload battery charger should be sized to withstand the line
loss from the LEV to the spacecraft.
