The Abbey Ridge Auto-Pilot (ARAP) software is an Observatory Automation Language developed by Dave Lane to automate the operations and image processing at the Abbey Ridge Observatory. It has been under constant development since 2003. Beginning in 2014, it was significantly enhanced and is now used to automate three robotic observatories: the Burke-Gaffney Observatory and Mini-Robotic Observatory at Saint Mary's University and the author's Abbey Ridge Observatory.
ARAP runs powerful text-based scripts containing English-like commands, in effect creating a rich observatory control language, that makes it very easy to automate observatory functions. This language is called DTL (Dave's Telescope Language!).
