Constant vessel traffic, noise from active depth sounders and a complex thermal structure characterise the scene. The reliable detection of underwater targets in the acoustically hostile environment of a seaport, harbour or marine terminal using sonar is a notoriously difficult challenge to overcome. The user also has the option of using Scylla to broadcast live messages if specific instructions need to be communicated to the diver. The message can be used to instruct the diver to alter course or surface. If a diver enters a restricted zone, Scylla broadcasts a pre-record audio message that can be heard by the diver at up to 600 metres away. Scylla is an optional accessory for the Sentinel sonar head which adds an audible, non-lethal warning and deterrent capability. We also offer a military-only variant, Sentinel XF, not available to private or commercial users. Its small topside footprint means it’s perfect for short-term operations using offshore patrol vessels (OPVs) and temporary sites on shore.
SENTINEL TECHNOLOGIES PORTABLE
Our Sentinel expeditionary system is a portable diver detection sonar (PDDS). Support for networked sonar is also offered, meaning that entire waterfronts can be protected using a single operator station. It can be used as a standalone security sensor or integrated with third-party command and control (C2) security systems. The base system, Sentinel, is configured to meet the needs of commercial and infrastructure facility protection projects. In fact, once it’s set up, Sentinel can be left to run autonomously.
SENTINEL TECHNOLOGIES SOFTWARE
We’ve engineered all the complexity associated with configuring and operating advanced sonar technology into easy-to-use software meaning that your security personnel don’t need to be sonar experts to use it.
SENTINEL TECHNOLOGIES INSTALL
Sentinel is small and lightweight so is quick to deploy from a boat, install in a port or fix along a coastline – providing you with an instant underwater security shield. With the ability to identify divers at ranges of up to 900 m and UUVs at 1,200 m, Sentinel takes reliable, long range underwater intruder detection to a new level and since its introduction, has been used in CNI, vessel and VIP protection duties around the world. Sentinel, developed by our sister company Wavefront Systems and manufactured and commericalised by Sonardyne, detects, tracks and classifies divers and uncrewed underwater vehicles (UUVs) approaching a protected asset from any direction and alerts security personnel to the threat. Outlines the Level-1B, Level-1C and Level-2A data products that are available to users, including the Level-1C tiling grid.Whether it’s protecting a commercial harbour, naval vessel, private yacht, critical national infrastructure facility or waterside residence from the threat of attack, Sentinel is cost-effective commercial-off-the-shelf (COTS) underwater security technology that is in service globally, easy to operate and proven in all theatres of operation. This section provides a brief description of the mission and the main thematic areas and services such as land monitoring and climate change.ĭescribes primary and secondary objectives of the Copernicus Sentinel-2 mission.ĭescribes the satellite platform and the communication links, the main instrument of the Sentinel-2 mission, the MultiSpectral Instrument (MSI), as well as the orbit characteristics of the mission.ĭescribes the Flight Operations Segment ( FOS) and the Payload Data Ground Segment ( PDGS) of the mission. It also addresses the related heritage missions, thematic areas and Copernicus services, orbit characteristics and coverage, instrument payload, and data products. This Sentinel-2 Mission Guide provides a high-level description of the mission objectives, satellite description and ground segment. It aims at monitoring variability in land surface conditions, and its wide swath width (290 km) and high revisit time (10 days at the equator with one satellite, and 5 days with 2 satellites under cloud-free conditions which results in 2-3 days at mid-latitudes) will support monitoring of Earth's surface changes.įor mission planning and updated coverage status information, see the Revisit and Coverage page. The Copernicus Sentinel-2 mission comprises a constellation of two polar-orbiting satellites placed in the same sun-synchronous orbit, phased at 180° to each other.
