JSATS AMT
Juvenile Salmon Acoustic Telemetry System
Acoustic Micro Transmitter
= 1 mm2
L-AMT-1.416
L -AMT-1.421
The Lotek JSATS AMT – Juvenile Salmon
Acoustic Telemetry System Acoustic Micro
Transmitter – was developed to satisfy the
research and regulatory requirements for
monitoring juvenile salmon in the Columbia
River Basin. The transmitter’s small size and
relatively long operational life permits tracking
of sub-yearlings throughout their natural
environment while minimizing impact upon
them.
L-AMT-8.2
L -AMT-5.2
The Lotek JSATS AMT transmitter is compatible
with JSATS receiving systems and utilizes
a Binary Phase-Shift Keying (BPSK) coding
system that allows for tens of thousands of
unique IDs on a single acoustic frequency. Each
transmission consists of an ID and check sum
delivered in less than one millisecond thereby
minimizing the probability of mis-identification
or interference from code collision.
Key Features
• Small size and light weight (0.28g) - suitable for small fish and sub-yearling applications
• Over 65,000 unique Ids - embedded check sum reduces error rate
• Sub-millisecond ID message length provides long life and reduced “code collision” rate
• Used for autonomous monitoring presence/absence
• Used for wireless positioning in 2D via Lotek UMAP positioning system
• Now available as JCART combined acoustic/radio transmitter compatible with
SRX (400/600/800/DL) radio receivers and WHS 4000 acoustic receivers
