Geospace Seismic Recorder (GSR)

Autonomous Nodal Data Acquisition

The GSR is designed for autonomous nodal seismic data recording. The self-contained unit includes 1 to 4 channels of 24-bit digitization, an integrated/high sensitivity GPS receiver, built-in test signal generator, up to 4 GB per channel of non-volatile solid-state data storage, and a high-speed data port. The unit is housed in a sealed case, with input connector, extended life battery connector/data port connector.

The GSR:

• Delivers high resolution with a 24-bit delta-sigma ADC
• Has a built-in GPS receiver and disciplined clock
• Is capable of up to 30 days of continuous recording
• Is compatible with explosive, vibratory and impulsive energy sources
• Accepts standard analog sensor inputs
• Has a built-in test generator
• Can be configured for 1, 2, 3 or 4 channels
• Has an LED Status/Deployment State Indicator

All this in a compact ~2 lb (0.9 kg) rugged and water-resistant package.
