The set of Minor Frames 1-60 are repeated five times with these changes (also MF and PHA increment consecutively):

 

In the second set of 60 MFs (61-120 MF), for MF72 replace the R/S G13 in MF24 with R/S G14. For MF114 replace the R/S G11 in MF54 with R/S G12.

 

In the third set of 60 MFs (121-180), for MF144 replace the R/S G13 in MF24 with R/S G15. For MF174 replace the R/S G11 in MF54 with R/S G13.

 

In the fourth set of 60 MFs (181-240) for MF 204 replace the R/S G13 in MF 24 with R/S G11. For MF 234 replace the R/S G11 in MF 54 with F/S G16.

  

In the fifth set of 60 MFs (241-300), for MF 264 replace the R/S G13 in MF 24 with R/S G12. For MF 294 replace the R/S G11 in MF 54 with R/S G17.

 

This structure repeats itself every 300 MFs. See Figure 5.3-6 for further clarification.

QUICK FACTS

Manufacturer: Voyagers 1 and 2 were built in the Jet Propulsion Laboratory in Southern California.

Mission Duration: 40+ years have elapsed for both Voyager 1 and Voyager 2 (both are ongoing).

Destination: Their original destinations were Saturn and Jupiter. Their current destination is interstellar space.
