iRobot® 1KA Seaglider™

iRobot Seaglider

Collect data from the ocean for months at a time...
Perform persistent surveillance and reconnaissance...
Acquire data at a fraction of the cost of traditional vessels and instruments...


The iRobot 1KA Seaglider is a deep-diving UUV designed for missions lasting many months and covering thousands of miles. Seaglider measures temperature, salinity and other quantities in the ocean, sending back data using global satellite telemetry. More than 135 Seaglider UUVs have been delivered to customers worldwide, including the U.S. Navy, government agencies and research organizations.

Key Features

1KA Seaglider uses state-of-the-art oceanographic instrumentation to precisely measure temperature and conductivity as a function of depth. In addition to research applications, these measurements provide sound velocity profiles that are critical for characterizing acoustic propagation models.
1KA Seaglider operates at depths ranging from 50 to 1,000 meters, gliding up and down for up to seven months at a time using a buoyancy engine to change its density. Shifting internal masses provide both pitch and roll control for maneuvering.
1KA Seaglider communicates via Iridium satellite phone, sending back data and receiving commands. Data can be uploaded every time Seaglider surfaces.
1KA Seaglider comes prepared for deployment; the user sets the mission parameters with the base station from anywhere in the world and begins the mission. If necessary, Seaglider can be reprogrammed and redirected each time it surfaces.
