Oceanography Datalogger
Spectre series Oceanography Datalogger is a specialized data logging system used for oceanographic and environmental monitoring.
Rugged SOSA™ Aligned SBC for Defense Avionics
Key Features
Low-power ARM Cortex-A5 processor for continuous data acquisition and control
Integrated multi-sensor interface (analog inputs, serial, CAN) to connect oceanographic sensors
1 GB DDR3 SDRAM and 8 GB eMMC Flash for buffering and local storage
Built-in GPS receiver and real-time clock for timestamping data
Wireless communication support (Iridium satellite, Cellular, or RF link) for data offload
Operates on battery/solar power with intelligent power management (sleep modes)
Sealed IP67+ enclosure resisting saltwater corrosion and ingress
Supports remote configuration and firmware updates
Overview
- Housed in a rugged enclosure, it features an ultra-low-power ARM Cortex processor and solid-state storage to collect multi-channel sensor data (temperature, pressure, wave motion, etc.) on ocean buoys or unmanned platforms.
- With long-term reliability in harsh marine conditions, it supports remote data logging and periodic transmission of collected data for naval and climate research.
