About this file
The document is a Salient Characteristics specification for Acoustic Doppler Systems (S25071), detailing technical requirements for three specific systems: two Acoustic Doppler Current Profiling (ADCP) Systems, two Pulse-Coherent Mode systems, and one 3D Acoustic Doppler Velocimeter (ADV). The ADCP systems must have a 2 MHz operational frequency, 3-beam configuration, 12 VDC battery power, built-in sensors for temperature, compass, tilt, and pressure, and a depth rating of at least 500 m. The 3D ADV must have a sampling frequency up to 64 Hz, velocity measurement accuracy of +/-5%, onboard Altitude and Heading Reference Sensor (AHRS), and communication capabilities including RS-422 and Ethernet.
The related federal contract opportunity is a U.S. Geological Survey small business set-aside solicitation (RFQ 140G0125Q0157) for delivering these Acoustic Doppler Systems to West Sacramento, CA within 30 days of purchase order receipt. The solicitation will be issued on 8/6/2025, with written quotes due on 8/11/2025 at 11:00 AM ED. The anticipated contract award date is 9/1/2025, with NAICS code 334511 and a size standard of 1,350 employees. Vendors must be registered in SAM.gov, and questions can be emailed to Cynthia Nicanor at cnicanor@usgs.gov before 8/7/2025 at 11:00 AM ED.
