Revalidated or Reaffirmed Date:
This standard describes the use of spread spectrum modulation in RF satellite communications systems and presents a detailed specification of the particular PN spread formats implemented in the low rate data transmission and PN range tracking services currently used by NASA systems. The functions and required capabilities of each element of PN spread links are also provided, including the typical signal flow and equipment characteristics and constraints involved.
The document has been cancelled due to the fact that it no longer contains current and valuable information.
