Demonstration architecture
Functional chain, transport boundary, interfaces and reference configuration.
USE CASE / ACOUSTIC BUOYS & RF LINK
Test the signal
through to the receiving system.
An acoustic buoy transmits information to a receiver and a processing chain. The requirement is to verify that radio transport preserves useful information, then select the resources needed for the trial area.
Application scenario · proposed engineering contribution
Define your trialTHE FUNCTION TO PRESERVE
Qualify the transport
and the received result.
OndOcéan proposes a preliminary radio study, relay selection and placement, interface integration and the trial plan. The source, receiver and reference processing are identified with the client.
- 01Reference source
Buoy or simulator defined for the trial.
- 02Radio transmission
Signal and interface to transport.
- 03Link & relay
Direct path or elevated relay site to compare.
- 04Reception & processing
Result compared with the reference.
- Before the study
- Specify the radio band, whether the stream is analogue or digital, the interfaces, positions and expected reception result.
- OndOcéan scope
- Coverage, transport boundary, relay, interfaces and trials. Development of the complete simulator or acoustic processing requires a separate scope agreed with the client.
EVIDENCE TO PRODUCE
Measure what supports
a decision.
The scenario is at the proposal stage. Criteria are agreed before the trial; results are then tied to the configuration, location and conditions actually tested.
| Question | Expected evidence | Decision |
|---|---|---|
| Does the stream remain usable? | Compare the result after transport with the reference chain. When DIFAR processing is used, its result is included in this comparison. | Validate the transport boundary and interfaces. |
| Does the link hold across the area? | Coverage, received signal and availability measurements. Useful throughput, latency and losses are recorded when transport is digital. | Identify gaps and operating conditions. |
| Which relay provides a useful improvement? | Compare the direct path with the positions, heights and supporting platforms selected in the trial plan. | Select a configuration sufficient for the scenario. |
A PACKAGE FOR THE NEXT STEP
Deliverables defined
before work begins.
A preliminary study can form the first project. Integration and the trial campaign are quoted according to the interfaces and resources available.
Coverage study
Calculation assumptions, candidate configurations, relay height and position.
Instrumented trial plan
Scenarios, measurement points, data acquisition and acceptance criteria.
Report & recommendation
When a trial is commissioned: observed results, limits and recommended architecture.
FROM BENCH TO FIELD
Prepare deployment
with the operator.
The reference bench and the quayside or offshore area are defined with the client. Relay height is selected based on the study and site constraints.
- Reference bench
- Accessible source and receiver, identified interfaces, planned power supply and data acquisition.
- Trial area
- Documented positions or route, antenna locations, access to measurement points and operating conditions.
- Relay platform
- An existing mast or elevated site is assessed first. A Méduse tethered balloon can be studied according to payload, power supply, anchoring and site conditions.
- Equipment & compliance
- Models, instructions and compliance documents for the selected equipment are checked against the project’s band and use.
DEFINE THE FIRST STEP
Which chain do you want to test?
Specify the source, receiver, result to preserve and proposed trial area. These elements help define the preliminary study and the resources needed.
