Digitizer 6 ChannelCategories: Digitizer
From volcanic explosions to fire ants, we know that trying to collect quality seismic data can be both a costly and a logistical nightmare. From experiment design to publishing, Pegasus reduces time in the field, the need for on-site station health checks, inventory management, and power related costs. Pegasus sets new standards for flexibility, efficiency, and data quality delivered by a standalone, portable, digital recorder. The Pegasus digitizer is well suited for broadband and passive node deployments, which focus on full waveform, full wavefield imaging, and rapid aftershock research.
MINIMIZE STATION INFRASTRUCTUREWith a power consumption of <200mW, Pegasus significantly reduces battery requirements, station size, and weight allowing for efficient and cost-effective portable deployment of larger campaigns over a longer period of time.
MINIMIZE FIELD EFFORTMinimize the time required to retrieve and process complete data sets. Retrieve one month’s worth of data in MiniSEED format along with StationXML metadata, State of Health and comprehensive project audit data in under 10 seconds.
