PN Ranging Generator (414.1-B-3)

Group: CCSDS > Ranging

CCSDS 414.1-B-3 Pseudo-noise Ranging encoder

Parameters

Encoder type

• Description: Whether to use free-running or regenerative mode
• Automation reference: EncodingType

Identifier	Value	Description
FreeRunning	Free-running	The encoder generates a continuous stream of chips with a freerunning counter. When receiving chips it compares with an internal free-running counter
Regenerating	Regenerating	The encoder produces chips based on the indices receive on the input

Code

• Description: Which chip code to use
• Automation reference: Code
• Type: enumeration

Identifier	Value	Description
T2B	T2B	Tausworthe, v=2
T4B	T4B	Tausworthe, v=4

Bits per packet

• Description: Number of PN sequence bits to transmit per packet
• Automation reference: BitsPerPacket
• Enablement: EncodingType == FreeRunning
• Type: integer
