Projects
SeaLandAire has an extensive resume of projects that showcase our capabilities
PHASE
Precision High Altitude Sonobuoy Emplacement
Precision High Altitude Sonobuoy Emplacement (or PHASE), is a Phase II SBIR effort investigating sonobuoy hardware and software adaptations to facilitate highly accurate placement from high altitude launches. The project is important because of the expected concept of operations changes associated with the new P-8 Poseidon anti-submarine warfare aircraft.
Compact Riverine AUV
Compact Riverine Autonomous Underwater Vehicle
SeaLandAire has led in the development of a compact, light-weight {less than 20 lbs) Autonomous Underwater Vehicle (AUV) designed to map and report bathymetry and intrusive objects in a loosely designated channel.
CMAS
Commandable Mobile ASW Sensor Propulsion
SeaLandAire designed and build a full 6 Degree-of Freedom (DOF) propulsion and steering tail-cone assembly, navigation module with required software for a new A-size mobile training target. The propulsion cone (4.87” in diameter and 9” long) houses a brushless DC motor, 4 RC servos, 3 PCBs, and the appropriate static and dynamic seals to allow the unit to function to depths of several hundred feet of water.
POS-SKB
Persistent Ocean Surveillance Station Keeping Buoy
SeaLandAire completed Phase I and Phase II contracts for Persistent Ocean Surveillance Station Keeping Buoy (POS-SKB) in response to DARPA BAA 04-33 Station-Keeping Energy Harvesting Sensors. The system was intended to provide continuous un-moored acoustic surveillance within a given watch circle for extended periods of time. As such, the primary focus of the program revolved around balancing the competing requirements for station keeping and energy harvesting while still providing a viable acoustic sensor.
VIVACE
Large Scale Vortex Induced Vibration for Renewable Energy
SeaLandAire provided engineering support services to Vortex Hydro Energy to design, develop, and test a large scale renewable energy device based on the principle of vortex induced vibrations – particularly at resonance of a high mass oscillating system.
GATEKEEPER
Autonomous Surface Vehicle for Persistent Observation & Communication
The Gatekeeper was designed to provide a solution for an unamnned, long-life perimeter sensor fence at a known location. Because of the required long life capability, it was required that it harvest energy from the ocean surface.
MDAR / MCIAS
Miniature Directional Acoustic Reciever & Miniature Commandable Impulsive Acoustic Source
The Miniature Directional Acoustic Receiver (MDAR) and Miniature Commandable Impulsive Acoustic Source (MCIAS)—affectionately termed ‘mini buoys’—are SeaLandAire’s response to saving volume and weight without sacrificing performance in anti-submarine warfare sensors. These buoys are 1/16th the size of typical A-size sonobuoy and are completely packaged in an MJU-10/B flare housing. Both mini buoys were developed with SBIR funds.
CSP
Covert Sensor Package / Threat Spectrum Direction Finding Unit
SeaLandAire developed a network of sensor nodes capable of detecting and localizing (direction) gunfire in contested environments. Two unique Unattended Ground Sensor (UGS) designs were developed to improve performance through data fusion. The Gateway unit contains an unstructured self localized array of microphones providing acoustic beamforming, and served as the hub for the RF network.
MARS
Moored Acoustic Reference System
The purpose of the SeaLandAire Moored Acoustic Reference System (MARS) is to monitor ambient noise and subsurface acoustic communication signals (underwater sounds). It consists of a modified sonobuoy transmitter and hydrophone mounted to a ridged foam float. Replaceable modules contain rechargeable batteries, surface electronics, RF antenna for signal transmission to a shore station, and navigation light.
