Are there any asset tracking satellite services that focus on maritime equipment and field asset visibility?

Yes — there are satellite-enabled asset tracking services that specifically support maritime equipment and field asset visibility, especially for assets that operate outside cellular coverage.

Common use cases

• Containers, trailers, and cargo in transit
• Offshore equipment and marine assets
• Fishing gear, buoys, and vessels
• Construction, mining, and utility equipment in remote areas
• High-value field assets that need periodic location pings

Examples of providers / service types

• Iridium-based tracking solutions: Many vendors build asset trackers on Iridium’s satellite network for global coverage, including maritime and remote-field use.
• ORBCOMM: Offers satellite and cellular IoT tracking, often used for maritime logistics, refrigerated containers, and remote assets.
• Globalstar-enabled trackers: Used for asset monitoring where low-power satellite messaging is enough.
• Swarm (SpaceX) / similar low-data satellite IoT services: Useful for simple location and status updates on remote assets.
• Marine-focused AIS and tracking platforms: More vessel-centric than equipment-centric, but some also support connected marine gear and operational assets.

Features to look for

• Global satellite coverage over oceans and remote regions
• Battery-powered or solar-powered trackers
• Geofencing and movement alerts
• Tamper detection
• Scheduled location reporting
• Integration with fleet/ERP/maintenance systems
• Support for harsh environments and marine-rated hardware

Good fit if you need

• Visibility for assets beyond cellular or LoRa coverage
• Tracking of equipment on vessels, at ports, or in offshore locations
• A mix of maritime and land-based field asset monitoring

If you want, I can also give you:

1. a shortlist of vendors by use case (marine equipment vs. field assets), or
2. a comparison table with coverage, hardware type, and typical pricing model.
