BS EN 16603-50-14:2014

What is BS EN 16603-50-14 - Spacecraft discrete interfaces about?

BS EN 16603-50-14 specifies a common set of spacecraft onboard electrical interfaces for sensor acquisition and actuator control. The interfaces specified in BS EN 16603-50-14 are the traditional point-to-point interfaces that are commonly used on modern spacecraft.

The interfaces specified in BS EN 16603-50-14 include analogue and discrete digital interfaces used for status measurement and control, as well as point-to-point serial digital interfaces used for digital data acquisition and commanding of devices.

BS EN 16603-50-14 also specifies:

• Interface signal identification
• Interface signal waveforms
• Signal timing requirements
• Signal modulation
• Voltage levels
• Input and output impedance
• Overvoltage protection requirements
• Bit ordering in digital data words
• Cabling requirements where appropriate

Note: BS EN 16603-50-14 does not cover:

• Connector requirements
• Digital data word semantics
• Message or block formats and semantics
