Key Features & Benefits

• ​High-Resolution Passive Acoustic Monitoring
  Broadband SPL data (20 Hz–20 kHz, 31 bands) enables background noise characterization, improved signal detection, and near real-time acoustic awareness 
• ASW Hydrophone Systems
  Teledyne PAM sensors with industry-standard HTI-90U hydrophones deliver accurate, reliable acoustic measurements 
• Multi-Sensor Ocean Profiling
  Combined acoustics, CTD, and additional sensors deliver environmental context for acoustic analysis and environmental modeling 
• Mission-Configurable Sampling
  Adjust depth, duration, gain, and triggers to optimize data collection for specific missions and environments 
• Advanced APEX Mission Capability
  Mission planning supports time or depth-based mission sequencing, customizable sampling schemes, and under-ice avoidance behaviors from 0-1000m 
• Secure, Flexible Communications
  Iridium (RUDICS & SBD) with encryption enables secure, near real-time data transmission 
• Long-Duration Autonomous Operation
  Long endurance profiling, months instead of days, with abundant data; satellite telemetry exfiltration; and no requirement for servicing and recovery 
• Rugged, Air-Deployable Design
  Deploy rapidly and operate reliably in extreme conditions, including polar environments 
• Real-World Proven, Operational Platform
  Over 12,000 APEX floats deployed with established military METOC integration​
