SR3001 Trident Acoustic Receiver-Datalogger

Used with coded acoustic tags in larger studies for fish tracking applications


  • Completely submersible electronics package, to 100 meters
  • Retrieve data via removable memory card
  • Part of a complete sonic fish monitoring system that includes tags, tag programmer, and receivers

The most sensitive acoustic receiver on the market ... from the telemetry receiver leaders.

The SR3001 Trident Acoustic Receiver is  a self sufficient receiver and data-logging system for the detection of acoustic transmitters (including JSATS). Using advanced digital signal processing (DSP) algorithms, the Trident is the most sensitive JSATS receiver available, which is why ATS was selected to supply the model SR5000 Trident, predecessor to the SR3001 Trident, for the Army Corps of Engineers.

The SR5000 Trident beat out the competition in rigorous, head-to-head field trials conducted by the Corps.  The message length is only 744 milliseconds in length, saving power and reducing signal collisions. Other code schemes on the market are considerably longer.

The Trident features a removable flash card for data storage. A USB port may be used to check the function and battery status of the receiver.

Featuring New Rechargeable Battery System

ATS sells a battery charger that can charge up to 4 rechargeable battery packs at a time. View flyer to find out more.

Modes of Operation
Receiver detects, decodes, and stores to memory all valid tag codes. Optionally, the receiver can record environmental information including ambient external temperature (°C), and deviation from vertical (degrees).
Diagnostic Information
Receiver records at user defined intervals: battery voltage, and number of beacon tags detected since last diagnostic check.
Optional Sensors:
Ambient external temperature (°C), and position in digress relative to the vertical hydrophone position (tilt)
Direct/cabled communications: Direct connection to receiver via USB allows user to set up deployment site identification, clock synchronization, access to stored date, and links to diagnostic sensors.
PC User interface
Included software provides a graphical user interface to retrieve data and perform setup functions
