One of the smallest acoustic transmitters in the world.

The Juvenile Salmonid Acoustic Telemetry System (JSATS) was developed by the Army Corps of Engineers and its partners to study fish behavior in freshwater and marine environments. ATS has been manufacturing large numbers (more than 10,000 tags per year) of acoustic tags for the JSATS program since 2007.

Through our innovative designs, the JSATS transmitter has significantly decreased in size, increased in power output, and become easier to deploy in the field. We've achieved these improvements while still offering another ATS trademark: low cost.

The JSATS system uses a binary phase shift keyed (BPSK) code pulse to achieve a code set of over 65,000 individual ID's. The pulse rate interval (PRI), code ID, and duty cycling (sleep/delayed activation) are user configurable through the use of the highly portable ATS Pinger Dish. The pulse train contains a 7-bit Barker code, 16-bit tag ID code, and 8-bit cyclic redundancy check (CRC). The message is only 744 microseconds in length, so the short on-time saves power and reduces signal collisions as compared to other standard timing code sets on the market.

ATS manufactures acoustic transmitters using strict process control procedures and part traceability to insure a reliable product.
