Totem ECDIS, not the complete FELCOM 15 system. The complete FELCOM 15 usually consists of the IC-115 antenna unit, IC-215 terminal unit, junction box, distress/alarm units, and other accessories depending on the configuration.Electronic Chart Display and Information System – ECDIS for vessels, designed to assist maritime officers in route planning, voyage monitoring, electronic chart management, and enhancing navigation safety on the bridge.

The most outstanding feature of Totem ECDIS is Decision Support Tool – DST, a collision avoidance decision support tool based on AIS/ARPA data and the international collision avoidance rules COLREGS 1972.

. Totem ECDIS integrates Decision Support Tool DST.

Unlike conventional ECDIS systems that only warn of collision risks, Totem ECDIS DST can provide suggestions for changes in heading or speed to assist the OOW/Master in handling the situation.

Information is calculated automatically for multiple targets within the user-defined range. Parameters such as Range, CPA and TCPA are used to assess risks and support the provision of appropriate maneuvering recommendations.

Supports collision avoidance according to COLREGS

Totem ECDIS is designed to assist in collision avoidance according to International Regulations for Preventing Collisions at Sea 1972 – COLREGS. This is a key differentiator, enabling the system not only to display alerts but also to assist the watch officer in evaluating maneuvering options.

However, DST is a decision support tool, not a replacement for the master's or officer's responsibility for observation, real-time situation assessment, radar/AIS usage, and COLREGS compliance.

GPS Validation detects positional deviation

A critical safety feature of Totem ECDIS is GPS Validation. The system monitors the discrepancy between Dead Reckoning – DR position and GPS position.

If the deviation exceeds allowable limits within a set timeframe, the system issues an alert. This feature helps detect potential positional deviation or GPS spoofing during operation.

Watch Take Over supports watch handover

Watch Take Over is the procedure to support the marine officer when starting the watch. This procedure helps the OOW check the operational status of the system, sensor data, charts, chart licenses, and important settings.

The check steps are logged for later auditing. Thus, Totem ECDIS helps standardize the handover process and increase transparency in bridge operations.

EDA analyzes near-misses and bridge team performance

Totem ECDIS support EDA – E-navigation Data Audit, allowing for analysis of historical data to detect near-miss situations and assess how the bridge team operates the vessel.

This feature is useful for shipowners, safety management teams, and training departments. EDA data can support bridge team performance evaluation, improve watchkeeping procedures, and enhance operational safety.

AIS update and AIS messages directly from ECDIS

Regarding AIS target management, Totem ECDIS allows direct AIS updates from the ECDIS system. Additionally, the device supports sending and receiving AIS messages using a full keyboard.

This feature makes AIS data entry, secure message sending, and information exchange on the bridge more convenient, especially in situations requiring quick coordination.

Radar Overlay enhances situational awareness

Totem ECDIS support Radar Overlay, allowing connection of two radars on a single radar overlay card. Radar images can be cross-referenced with electronic charts, helping marine officers increase situational awareness.

Radar Overlay is particularly useful when comparing radar targets with ENC data, checking position discrepancies, or assessing the vessel's surroundings in high-traffic areas.

Supports Electronic Charts and AIO

Totem ECDIS supports multiple chart formats such as C-MAP ENC, official ENC database, Jeppesen CM93/3, IHO S-57and in appropriate configurations. These technologies help improve the quality of positioning data when the operating area has corresponding augmented signal support.IHO S-63.

AIO is a layer of information provided by UKHO to AVCS users, enabling the display of critical maritime update information directly on ENC. This assists operators in managing chart information more effectively during route planning and voyage monitoring.

Suitable for Cruise, Energy, Merchant, and Ferry.

Benefits of using the

Totem ECDIS helps improve maritime safety through its ability to warn and support decision-making for collision avoidance. The DST tool provides additional maneuvering recommendations for the OOW to have a better basis for assessment in multi-target situations.

FeaturesGPS Validation helps increase the reliability of position data, especially when there is a risk of GPS deviation or GPS spoofing. This is an important factor for ships operating in complex areas or areas with a risk of navigation signal interference.

Watch Take Over helps standardize the watch handover process. Officers can check sensors, charts, licenses, and system status before starting their watch, reducing the risk of missed checks during handover.

EDA helps shipowners and safety management teams analyze historical data, detect near-misses, and evaluate bridge operations performance. This allows businesses to improve training, watchkeeping procedures, and safety culture.

CapabilitiesAIS update, AIS messaging, Radar Overlay, and Planning Station make Totem ECDIS suitable for modern bridges where multiple systems need to be integrated and share data over LAN.

Suitable for

• Commercial vessels requiring an ECDIS with collision avoidance support tools.
• Cargo ships, container ships, oil tankers, chemical tankers.
• Passenger ships and ships operating on international routes.
• Ships with high navigation density, frequently encountering multiple AIS/ARPA targets.
• Shipowners needing tools to analyze near-misses and audit bridge team performance.
• Ships requiring improved watch handover procedures.
• Bridge systems needing Radar Overlay, AIS messaging, and VDR connection via LAN.
• Operators wishing to use Planning Station or optional Captain’s ECDIS.
