Depth of Measurement | |
Telemetry | - Iridium SBD with Iridium 9602 Modem
|
Positioning | - Multi-constellation GNSS receiver supports GPS and other GNSS constellations depending on receiver configuration.
- GNSS acquisition windows are optimized for low-power operation and may be extended upon request to improve fix reliability or enable augmentation features where available, with a corresponding reduction in battery life.
|
Standard Battery Pack | - 12 V; 8S8P alkaline AA cells; estimated 24 Ah capacity
|
Battery Lifespan | - Operating life: 1–24 months with standard 24 Ah battery pack, depending on sampling/transmission rate and field conditions. Harsh weather or rough seas can increase GPS acquisition time and transmission retries, reducing battery life.
|
Standard Status Sensors | - Battery Voltage
- GNSS Positions (GPS, GLONASS, Beidou, Galileo)
- Deployment Status (Float in/out of water)
|
Optional Status Sensor | |
Optional Sensors
| - Sea Surface Temperature (SST)
- High Accuracy Sea Surface Temperature (SST)
- Water Quality
|
Sampling Period | - Variable: 5 minutes to 12 hours
- Commandable: Change the period after deploying
|
Power Mode Switch | - A magnet, held in place with a hook-and-loop strap, switches the drifter from low-power mode to deployment mode when removed.
