Microstar
The Microstar Drifter is designed primarily for tracking currents at a depth of 1 meter, particularly suitable for coastal and shallow water environments. The Microstar Drifter is a versatile tool for various coastal and shallow water applications, including circulation and dispersion studies and environmental monitoring.
Telemetry
Iridium SBD (Short Burst Data) or optional Globalstar Smartone C
GNSS
Enhanced location accuracy with GPS, GLONASS, BeiDou, and Galileo for global, multi-constellation positions
Packaging
Box shipping is standard. An optional nylon bag is offered with internal padding for the surface float. For air deployments rigging with a parachute is available where the drogue opens automatically within 5 seconds of landing in the water
Battery
The Microstar is powered by a replaceable 12V, 15.6 Ah alkaline battery pack
Drogue
The Microstar is designed for easy storage, deployment, and recovery using a collapsible corner radar reflector design,
Sensors
Status sensors report GNSS quality, monitor the battery voltage and indicate whether the drifter is deployed or if the drogue is attached.
Optional sea surface temperature sensor available

Data Telemetry/Archiving/Distribution
Includes data conversion to scientific units, a web browser interface with a dashboard map and current array status, convenient downloading, and device and organization administration. Data is archived on Pacific Gyre servers, and an API interface is available to download data directly to customer web pages or applications such as Excel and Matlab
