Professional Use System Integration Ready USBL positioning kit (receiver + transmitter)

Cerulean USBL ROV Locator Mark II Receiver and Transmitter Bundle

Bundle consisting of a surface receiver module and an ROV-mounted transmitter for USBL-based underwater positioning. Designed to display ROV location on QGroundControl map views when integrated via supported interfaces. Includes Autosync behavior based on GPS/GNSS exposure at mission start.

Quick integration notes
  • Receiver and transmitter communicate acoustically; system output is available via serial communication and API (as supported by the device).
  • Autosync is performed by exposing both units to GPS/GNSS signals at the start of the mission (and optionally during operation).
  • Receiver input power is specified for DC operation; transmitter input power is specified for DC operation with burst-current considerations.

System Overview

System Type
USBL underwater positioning kit (surface receiver + ROV transmitter)
Primary Role
Track underwater vehicle position and present location data to supported mapping/control software.
Operating Environment
Underwater operation with receiver positioned on the surface and transmitter mounted on the ROV.
Configuration
Receiver + transmitter pair with Autosync behavior and serial/API connectivity for integration workflows.

Key Features

  • Provides a receiver + transmitter bundle for USBL acoustic positioning workflows.
  • Designed to support location display on QGroundControl map views when integrated.
  • Supports Autosync by exposing receiver and transmitter to GPS/GNSS signals at mission start (and optionally during operation).
  • Allows integration via serial communication and API (as supported by the device).
  • Designed with specified DC input power ranges for receiver and transmitter operation.
  • Supports TTL serial communication voltage levels with auto-sense behavior.
  • Provides specified update rate and ping frequency for system operation.
  • Designed for underwater deployments with a specified maximum depth exposure rating.
  • Supports setup where the receiver is near the operator and the transmitter is mounted on the ROV.
  • Includes mounting hardware components described for kit deployment.

Performance & Specifications

The system operates as a paired receiver/transmitter solution. At mission start, Autosync is performed by exposing both units to GPS/GNSS signals. During operation, positioning data can be forwarded through supported serial/API interfaces for display in compatible software environments.

Operational notes (manufacturer-stated)
  • Satellite acquisition is stated as typically occurring within 30 seconds of power-up for Autosync exposure conditions.
  • Receiver is stated as designed to allow operation from a laptop USB port when used with a serial-to-USB adapter.
  • Transmitter power supplies are stated to require sufficient burst current capability to avoid drop-out or erratic operation.

Mapping/Display Context
Designed to support QGroundControl map display integration.
Electrical Context
Receiver and transmitter specify DC input ranges; serial levels specify TTL voltage options with auto-sense.

Deployment Considerations

  • Receiver is typically positioned on the surface near the operator; transmitter is mounted on the ROV.
  • Autosync setup requires exposure of both units to GPS/GNSS signals at the start of the mission (and optionally during operation).
  • For transmitter power, use a supply capable of supporting burst current demands as stated by the manufacturer.
  • Lead time may vary; manufacturer listing indicates delivery in the 3–4 week range.

Compatibility

  • Designed for QGroundControl map display integration (as described by the manufacturer).
  • Serial comms voltage levels: 3.3V TTL or 5V TTL (auto sense).
  • Receiver DC input range: 4.5V to 16V DC (stated as < 1 Watt).
  • Transmitter DC input range: 5V to 28V DC (power values stated per voltage).

FAQ

Does this bundle include both the receiver and transmitter?
Yes. The bundle is described as including a transmitter mounted on the ROV and a receiver module located on the surface, along with a mounting ring and adapter.
How does Autosync work for this system?
Autosync is described as working by exposing the receiver and transmitter to GPS/GNSS signals at the start of the mission (and optionally at intervals during the mission).
What interface options are available for integration?
The product listing describes serial communication and API availability, and specifies TTL serial comms voltage levels (3.3V or 5V, auto sense).

Safety & Regulatory Notice (US)
