The PBS Satellite Service has undergone significant changes over the years. In the 1960s, the service was initially broadcast via satellite to a few select stations, but it wasn't until the 1980s that it expanded to reach a wider audience.
Satellite technology played a crucial role in the service's growth. With the launch of the first domestic communications satellite, Intelsat 1, in 1965, PBS was able to broadcast its programming to a national audience.
Despite its growth, the service faced significant challenges. In the 1990s, PBS struggled with the high costs of satellite transmission, which limited the number of stations that could access the service.
The service has continued to evolve, with the introduction of digital technology in the 2000s. This allowed for more efficient and cost-effective transmission of programming.

History of PBS Satellite Service
PBS launched its second-generation satellite interconnection system on March 1, 1978, which replaced their terrestrial-based system.
The system was a significant improvement, allowing all public television stations to receive programs via satellite by the end of 1978. This was made possible by the installation of satellite dishes at each station.
The system cost $39.5 million to implement and develop, and PBS initially used three full-time C-band transponders on the Westar 1 satellite to deliver programming.

Second Generation Launched
In 1978, PBS launched their second-generation satellite interconnection system, marking a significant milestone in their history.
The system was a major upgrade from their previous terrestrial-based interconnection system, which was no longer necessary once all public television stations were receiving programs via satellite by the end of 1978.
The new system cost $39.5 million to implement and develop, a significant investment that paid off in the long run.
The system utilized three full-time C-band transponders on the Westar 1 satellite at orbital position 99°W, with a fourth "occasional" transponder leased beginning in 1980.
This upgrade allowed PBS to deliver programming to a wider audience, with all public television stations now receiving programs via satellite.
In case of a failure of Westar 1, Westar 2 was designated as a backup at orbital position 123.5°W.
Westar 4, launched in 1982, replaced Westar 1 and offered 24 transponders, compared to Westar 1's 12 transponders.
This increased capacity enabled PBS to provide more channels and better service to its stations.
By the end of 1978, all public television stations were now receiving programs via satellite, marking a major shift in the way PBS operated.

1987: VideoCipher II Controversy
In 1987, a controversy surrounding the VideoCipher II encryption system made headlines.
The VideoCipher II was designed to scramble satellite signals, but it was later discovered that it had a major flaw that made it vulnerable to hacking.
PBS was one of the first organizations to use the VideoCipher II system, but it was a costly and inefficient solution.
The system required a separate encryption device for each satellite transponder, which added to the overall expense.
The VideoCipher II controversy highlighted the need for more secure encryption methods, and it led to the development of new technologies.
This marked a turning point in the history of PBS's satellite service, as they began to explore alternative solutions.

Scheduling and Programming
PBS Satellite Service offers a variety of programming selected from PBS's regular network services. This service is freely and nationally available from designated K and C-band broadcast satellites using free-to-air satellite dishes as small as three feet.
PBS Satellite Service provides a mixed variety of programming, including PBS Kids weekday programming, which can be received by local stations and aired live or tape-delayed. Local stations can choose to air these programs at different times, but the times listed are for the Eastern Time Zone (EST).

As of 2018, PBS satellite feeds can be received unscrambled using a free-to-air satellite receiver. Here are the coordinates for receiving the feeds:
- PBS at 125*W (on the AMC-21 satellite), K-band, unencrypted.
- LPB at 87*W (on the SES-2 satellite), K-band, unencrypted.
- PBS at 103*W (on the SES-3 satellite), C-band, unencrypted.
PBS-X provides two free national feeds in each format, one scheduled for the Eastern U.S., and the other, PBS-XP, on a three-hour delay to fit timezone differences for the West Coast.
