Seaglider


 
General 
Product Name:Seaglider
Description:Seagliderâ„¢ is an autonomous underwater vehicle (AUV) or underwater glider developed for continuous, long term measurement of oceanographic parameters. Rather than an electrically driven propeller, the vehicle uses small changes in buoyancy and wings to achieve forward motion. The system's pitch and roll are controlled using adjustable ballast (the vehicle battery).

Min. weight of AUV in air [kg]:52
Max. Weight of AUV in air [kg]:
Portable:Y
Crane required:N
Maximum payload [kg]:2
Maximum depth rating [m]:1000
Number of thrusters:0
Thruster specifications:
Hovering capabilities:Intrinsic
Operations 
Min. turning radius [m]:28
Launch and recovery system:Not required
Max. speed [kn]:0.5
Min. crew size :2
Min. required number of surface computers:2
Required size of storage room:2.438m x 0.914m x 0.914m while in crate
Other requirements:Iridium communications
Navigation and Payload 
Navigation sensors - standard:3 -Axis digital compass; Acoustic altimeter; Bathymetry map system; GPS (on surface)
Navigation sensors - optional:
Payload sensors - standard:Conductivity; Temperature; Pressure
Payload sensors - optional:WL Eco Triplets; SBE DO; Aanderaa Optode; PAR; Passive Acoustic; Microstructure Turbulence
Battery 
Total energy content [Wh]:4,700
Nominal battery power [W]:
Endurance at nominal power [hr]:6500

Telemetry and Control 
Acoustic telemetry:
Acoustic baud rate [bit/s]:
Radio telemetry:Y
Radio baud rate [bit/s]:
Max. Baud rate of ethernet connection [Mb/s]:
Data sent to the surface:pilot controlled; can download all or none of the data collected during last dive
Control parameters sent to the AUV:navigation control; science sensor sampling intervals; communications preferences
Emergency recovery procedure:vehicle pumps to full buoyancy; comes to and remains on the surface; position is transmitted via Iridium communications
More information 
Applications:marine environmental measurements; marine mammal detection; tactical oceangraphic surveys; persistent surveillance; data gateway
Distinguishable features :No external moving parts, making it very robust.
Commercial Options:This is a fully commercial product
