The Mission Operations Group at UC Berkeley's Space Sciences Laboratory operates a highly automated ground station
and presently a fleet of seven satellites, each with its own associated command and control console. However, the
requirement for prompt anomaly detection and resolution is shared commonly between the ground segment and all
spacecraft. The efficient, low-cost operation and "lights-out" staffing of the Mission Operations Group requires that
controllers and engineers be notified of spacecraft and ground system problems around the clock. The Berkeley
Emergency Anomaly and Response System (BEARS) is an in-house developed web- and paging-based software system
that meets this need.
BEARS was developed as a replacement for an existing emergency reporting software system that was too closedsource,
platform-specific, expensive, and antiquated to expand or maintain. To avoid these limitations, the new system
design leverages cross-platform, open-source software products such as MySQL, PHP, and Qt. Anomaly notifications
and responses make use of the two-way paging capabilities of modern smart phones.
