Avril Station was a Starfleet facility in operation in the mid 24th century, located between Station Kel-Artis and Cor Caroli IX. As of 2376, it was under the command of Commander Ling. In the 2350s, there was an attempt to apply the Sitok upgrade to Avril Station's computer system, which resulted in crashing their systems. It was determined that the benefits of applying the upgrade did not outweigh the costs of overhauling the station's hardware, and so it remained one of only a few Federation facilities not to incorporate Sitok's program.
