The Preferred Choice for Underwater Positioning of Small to Medium‑Sized ROVs!
Topside Receiver & Control Unit
The Topside Receiver & Control Unit serves as the "hub" of the underwater GPS system. It houses the Master‑D1 positioning computer board, which runs the Web GUI and API. Users can connect to the Topside unit via Wi‑Fi or Ethernet.
Pelican Case
Advantages
- Compact size and easy to transport
- IP67 waterproof rating
Remarks
- Positioning range available in 100m or 300m options
Locator Underwater Positioner
The Locator Underwater Positioner is a "signal transmitter" fixed to underwater vehicles/divers.
Locator U1
Advantages
- Fully self‑contained — no external power or integration required
- Simply attach it to an ROV or diver to start positioning
Remarks
- Battery runtime: 10 hours
- GPS lock required before diving (for outdoor use)
- Even with the 300m version firmware installed, the downward positioning range is still limited to a maximum of 200m
Locator A1
Advantages
- Can be positioned without GPS lock (suitable for indoor use)
- Provides accurate underwater positioning indefinitely without positional drift over time
- Deep integration possible via API
Remarks
- 1‑meter cable, connectorless
Underwater Baseline
The Underwater Baseline is used to receive acoustic signals from the positioner.
Underwater Receive Array
Advantages
- Enables quick and easy receiver deployment
- Receiver position remains stable.
Remarks
-With 10‑meter cable and Binder connector.
Underwater Receiver Kit
Advantages
- The array can be deployed according to actual needs.
- Cable length is selectable: 10m, 50m, or 100m.
Remarks
- The position of each receiver must be measured and manually entered into the host computer.
- Receiver installation must be ensured to be secure.
