The VDAC-Antelope Environment Monitoring Software package that addresses the special needs of the nuclear test treaty monitoring community. 

VDAC-Antelope Environment Monitoring Software is a distributed open-architecture UNIX-based acquisition, analysis and management software system designed to provide a comprehensive set of environmental monitoring data and processed information in real-time. Finely engineered as an all-in-one system, VDAC-Antelope Environment Monitoring Software integrates state-of-the-art technology and scientific advances, making it ideal for monitoring seismic events from local/regional, national and global networks and arrays. VDAC-Antelope Environment Monitoring Software takes full advantage of the extensive support services provided by the UNIX environment and standard TCP/IP network utilities over multiple physical interfaces.

Antelope consists of two major sub-systems:

• VARTS, the VDAC Antelope Real Time System
• VASIS, the VDAC Antelope Seismic Information System

The current generation of VDAC-Antelope Environment Monitoring Software provides full functionality for seismic network and array operations and control, including real time data acquisition from field digitizers, interactive control of field equipment, system state of health monitoring, automatic-calibration, real time automated data processing (detection, picking, seismic event association, seismic event location, archiving). It also offers interactive and batch processing, information system functions, automated distribution of raw data and processed results, batch mode seismic array processing and a powerful development toolkit for extending and customizing the system.

VDAC-Antelope Environment Monitoring Software makes easy the integration with environmental data such as temperature, wind speed, wind direction, barometric pressure and humidity.

The VDAC-Antelope Environment Monitoring Software Seismic Information System uses the relational database (RDBMS) formalism and the CSS v. 3.0 schema for information organization. VDAC-Antelope Environment Monitoring Software runs on the Sun Microsystems' Solaris operating system on both SPARC and Intel architectures. In addition to providing specific functionality for seismic monitoring systems, VDAC-Antelope Environment Monitoring Software provides a robust and versatile substratum of generic functions that can be used to support other non-seismic monitoring applications.
