DM860-GSM 3–5 NM Solar Marine Lantern with GSM Remote Monitoring

The DM860-GSM is a 3–5 NM solar marine lantern with integrated GSM telemetry for projects requiring remote monitoring and management of marine aids to navigation.

Built on the DM860 solar lantern platform, it combines reliable visual navigation marking with access to the Satvora 360 monitoring platform, allowing operators to check equipment status, receive alarms and perform remote configuration through PC or mobile devices.

The system supports both local SIM cards and factory-provided international SIM service, making it suitable for projects deployed in different regions.

Remote Monitoring for Marine AtoN

The main difference between the DM860-GSM and the standard DM860 is the addition of GSM telemetry and remote monitoring capability.

Instead of relying only on routine on-site inspections, operators can remotely access lantern and asset information through the Satvora 360 platform.

This is especially useful for navigation aids installed in offshore, remote or difficult-to-access locations.

Key Remote Monitoring Functions

• Remote asset monitoring
• Alarm management
• Remote configuration
• Maintenance management
• PC access
• Mobile access

Satvora 360 Monitoring Platform

The Satvora 360 platform provides a centralized interface for managing DM860-GSM units remotely.

Operators can access the platform through both PC and mobile devices, making it easier to monitor equipment condition and manage multiple marine assets from different locations.

Satvora 360 Functions

• Asset status monitoring
• Alarm notification
• Remote parameter configuration
• Maintenance management
• Multi-device management
• PC and mobile access

GSM Telemetry

The DM860-GSM uses GSM communication to transmit equipment data between the lantern and the monitoring platform.

This allows operators to obtain remote information from deployed navigation aids without being physically present at the installation site.

For projects where regular site visits are difficult, GSM telemetry provides a more efficient way to support routine monitoring and maintenance planning.

Flexible SIM Options

The DM860-GSM supports different SIM configurations according to project requirements.

Available Options

• Local SIM card
• Factory-provided international SIM service

Local SIM cards can be selected where suitable mobile network services are already available.

For projects deployed across different countries or regions, factory-provided international SIM service offers another communication option.

Reduce Routine Site Visits

Marine navigation aids are often installed in locations where inspection and maintenance require boats, personnel and suitable weather conditions.

By providing remote access to equipment information, the DM860-GSM can help reduce unnecessary site visits and allow maintenance teams to respond more efficiently when attention is required.

This does not replace necessary field inspection, but it provides operators with additional information before arranging on-site work.

Reliable 3–5 NM Navigation Marking

While GSM monitoring is the main feature of the DM860-GSM, the unit retains the core optical performance of the DM860 platform.

It provides a nominal visible range of 3–5 NM at T=0.74, with a high-efficiency LED light source and multiple navigation colours for different marine marking requirements.

Key Optical Features

• 3–5 NM nominal visible range
• High-efficiency LED
• Red / Green / White / Yellow / Blue / Yellow-Blue
• Vertical divergence ≥8°
• 256 programmable IALA flash characteristics
• LED lifespan ≥100,000 hours

Self-Contained Solar Power System

The DM860-GSM combines the lantern, solar panels, battery, control system and GSM communication function in one compact unit.

Four 3.5 W marine-grade mono solar panels charge the internal 12.8 V / 20 Ah LiFePO₄ battery, supporting autonomous operation without a separate external power supply.

Power Features

• 4 * 3.5 W marine-grade mono solar panels
• 12.8 V / 20 Ah LiFePO₄ battery
• Self-contained solar-powered operation
• Up to 25 days continuous operation
• Reduced requirement for external power equipment

Up to 25 Days Continuous Operation

The DM860-GSM supports up to 25 days of continuous operation, providing operating reserve for marine installations where maintenance access may be limited.

Its integrated solar charging system and LiFePO₄ battery are designed to support long-term autonomous operation in marine environments.

Local and Remote Configuration

In addition to remote configuration through Satvora 360, the DM860-GSM also supports local configuration through:

• Bluetooth
• RS232
• Keypad

This gives technicians multiple options during installation, commissioning and maintenance.

Remote access is useful for routine management, while local configuration remains available when technicians are working directly with the equipment on site.

GPS Synchronization

Built-in GPS synchronization allows multiple DM860-GSM lanterns to maintain synchronized flashing where coordinated navigation marking is required.

This function can be used independently of the GSM remote monitoring function.

256 IALA Programmable Flash Characteristics

The DM860-GSM supports 256 IALA programmable flash characteristics, allowing the lantern to be configured for different navigation marking requirements.

Combined with multiple available light colours, this provides flexibility for different marine AtoN applications.

Designed for Marine Environments

The DM860-GSM uses an optical acrylic lens and a marine-grade fiber-reinforced plastic base.

The enclosure is rated IP68 and is designed for continuous use in demanding coastal and offshore environments.

Structural Features

• IP68 waterproof rating
• Optical acrylic lens
• Marine-grade fiber-reinforced plastic base
• Operating temperature: −35°C to +65°C
• Compact self-contained construction
• Product weight: 5.3 kg
