We present the hardware and software systems implementing autonomous operation, distributed real-time monitoring, and control for the EBEX instrument. EBEX is a NASA-funded balloon-borne microwave polarimeter designed for a 14 day Antarctic flight that circumnavigates the pole. To meet its science goals the EBEX instrument autonomously executes several tasks in parallel: it collects attitude data and maintains pointing control in order to adhere to an observing schedule; tunes and operates up to 1920 TES bolometers and 120 SQUID amplifiers controlled by as many as 30 embedded computers; coordinates and dispatches jobs across an onboard computer network to manage this detector readout system; logs over 3~GiB/hour of science and housekeeping data to an onboard disk storage array; responds to a variety of commands and exogenous events; and downlinks multiple heterogeneous data streams representing a selected subset of the total logged data. Most of the systems implementing these functions have been tested during a recent engineering flight of the payload, and have proven to meet the target requirements. The EBEX ground segment couples uplink and downlink hardware to a client-server software stack, enabling real-time monitoring and command responsibility to be distributed across the public internet or other standard computer networks. Using the emerging dirfile standard as a uniform intermediate data format, a variety of front end programs provide access to different components and views of the downlinked data products. This distributed architecture was demonstrated operating across multiple widely dispersed sites prior to and during the EBEX engineering flight., Comment: 11 pages, to appear in Proceedings of SPIE Astronomical Telescopes and Instrumentation 2010; adjusted metadata for arXiv submission

The Combined Array for Research in Millimeter-wave Astronomy (CARMA) is a 15 element heterogeneous millimeterwave array developed and operated by a university consortium that will be expanded to 23 elements in 2008. Commissioning began in August 2005 after completion of the relocation of antennas from the Owens Valley Radio Observatory (OVRO) and the Berkeley-Illinois-Maryland Association (BIMA) arrays to a new high site and initial scientific operations began in April 2006. The array operates in the 3-mm and 1-mm bands and has a maximum resolution of 0.15 arc seconds. Most of the software and computing infrastructure for the array is new, allowing modern technology to be introduced and to provide a common interface for the disparate antenna types. The new system is proving to be both easy to use for routine observations and yet capable enough for the development of new observing techniques by the experienced astronomer. Some of the details of the computing and software are described here, with emphasis on the control system.

The software for the Thirty Meter Telescope (TMT) is currently in the specification and design phase. A decision was made early on to provide a common software package that will provide basic infrastructure and services to be used by all project software packages. A roadmap for defining Common Software was written. The first roadmap step of defining what should be included in common software was accomplished by analyzing similar projects. The result was the definition of a reference architecture for end-to-end observatory software systems called the Observatory Software Domain Architecture. This architecture was then used to define the specifications for the TMT common software. This paper describes the roadmap, the reference architecture, and the current definition of TMT common software.
