Before
The route and the segments where coverage is expected to be weaker.
Infrastructure inspection
Long routes, changing coverage, a truthful image.
An inspection flight runs tens of kilometres beyond line of sight. Coverage changes with altitude and the operator needs to know where the image was reliable.
Needs: Two networks at onceEvidence after the flightControl from a centre
Illustrative case study
Twenty kilometres of line
This is not a customer and not a flight that happened. It is a description of how this area would read if the image carried its age.
A high-voltage corridor, an illustration
The operator has a beyond-line-of-sight flight planned along a line. Coverage at altitude changes. A segment where the image froze must not look finished in the report.
In the example Platform splits the route into segments after the flight. Each has a frame age and time in Valid. A segment over the target is marked for another pass.
A second drone launches on the next segment while the first charges. The records are not mixed. The audit gets a pack, not a video without time.
In flight
Age and both networks are logged.
After
A segment over the target is not finished in the report.
AKIZU does not look for a damaged mast. It says whether the segment image is valid.
Image age through the example
The chart requires JavaScript.
The chart is a simulation. Move the slowdown and see when the example stops being under the 50 ms target. The target is not a measured result.
Deployment schematic
Where everything stands and how the image travels
The schematic is not to scale and is not a design for a specific site. It shows where the drone is, which two networks carry the frame and where the decision is made.
Numbers in the schematic
- 1Two drones launch from a station by the line.
- 2Segment 3 is a cell edge. That is where we expect a worse image.
- 3Both networks are logged for every segment.
- 4Platform splits the route into segments and time in Valid.
- 5The operator sees which segment is over the target.
- 6The report: a segment over the target is not finished.
Symbols in the schematic

- DDrone with AKIZU Brain

Red and blue beacons: police, state, the military in training. Orange: everyone else. The blink is only on screen. Schematic, design. The list beside it explains the codes in the drawing. The beacon is a payload from another maker, not an AKIZU product.
Concrete case
Minute by minute
The same illustrative case as above, written out in time. The times are an example. It is not a record of a flight that happened.
- 06:00Plan: five segments, two drones, a cell edge at segment 3.
- 06:20Drone 1 launches for segments 1 and 2.
- 06:41Segment 3 jumps over the target. It is marked for a repeat.
- 06:55Drone 1 charges. Drone 2 continues on segments 4 and 5.
- 07:30A repeat pass over segment 3 at another altitude.
- 08:00Report: four segments valid, one after the repeat. The records are not mixed.

Use options
Everything it can be used for in this area
Each row is a separate use. The Parts column says which AKIZU parts it would involve. Status N is a design, C is a target, U is unknown.
| Use | Who uses it | What AKIZU supplies | Parts | Status |
|---|---|---|---|---|
| A high-voltage line pass | Transmission operator | Age for each segment and time in Valid | Brain, SIM, Platform | N |
| Gas and oil pipelines | Pipeline operator | Segments that need another pass | Brain, SIM, Platform | N |
| A railway line | Rail infrastructure manager | An image with age at the tracks and crossings | Brain, SIM, Direct | N |
| Bridges and dams | Structure owner | A record of what was seen and when | Brain, Platform | N |
| An audit after a storm | Grid dispatch | A quick view of segments, not a video without time | Platform, Direct | C |
None of these uses is deployed today. A row is not an offer and not an authorisation to fly.
01
The problem today
01
Coverage at altitude differs from the ground
Operator coverage maps describe the ground. At flight altitude the drone may connect to more distant cells.
02
The authority wants evidence
A SORA risk assessment needs a description of the control loop, including delay.
03
Faults are found afterwards
Without a frame-age record it is hard to find out why the operator reacted late on a segment.
04
A fleet on a long line
Two drones shorten the day, but every segment needs its own pack. Otherwise a fault disappears between flights.
Without AKIZU and with AKIZU
The same situation, different information on the screen. Proposed behaviour, to be verified in a pilot.
| Situation | Without AKIZU | With AKIZU |
|---|---|---|
| The image is late | The image looks live; the pilot does not know how old it is. | Frame age is on the screen and the state changes to Reduced freshness. N |
| One network fails | The image freezes or breaks up. | The frame arrives over the second network; the switch is logged. N |
| You need to explain what happened | Video without exposure time and without commands. | Evidence package with image age, states and commands. N |
| The pilot is in a centre far from the drone | Latency changes and the pilot cannot see it. | The deadline guard warns when a command arrives late. N |
02
How it would work
- PlanThe operator enters the route. Platform shows segments where weaker coverage is likely.
- FlightBrain measures the age of every frame and the state of both networks.
- ReviewPlatform marks segments with reduced image freshness.
- AuditThe evidence pack goes into the operation documentation.
- Next segmentThe second drone launches while the first charges. Platform does not mix them into one record.
The flow is illustrative. AKIZU is in development.

Mission scenario
How many metres further the drone is than the image shows. Pick a scenario or set the speed and image age.
The interactive calculation requires JavaScript.
Scenario speeds are examples. 87.4 ms is the p99 measured internally over WiFi with a phone as transmitter, not on a drone.

Context
Flights beyond line of sight under SORA 2.5
EASA introduced SORA 2.5 in September 2025 and several states no longer accept the older version.
Operators offer priority on demand
Deutsche Telekom and Nokia demonstrated a drone whose network priority was temporarily raised at flight altitude.

How does image age differ from latency?
Network latency is only part of the journey. Image age is the time from frame exposure on the drone to its display to the operator. VERA attaches the exposure time to every frame and the station verifies it before display.
Does it work without a mobile network?
The AKIZU design is built around LTE and 5G. According to the manufacturer, the Starling 2 Max base platform also supports Wi-Fi and Microhard. Our internal measurement was done over WiFi.
Does AKIZU replace a BVLOS authorisation?
No. BVLOS flights need an authorisation in the Specific category based on a SORA 2.5 risk assessment. AKIZU Platform is meant to give the operator an image-age record as evidence for that assessment.

What the operator sees
The three image states in this area. Proposed behaviour, to be verified in a pilot.
The segment can be used in the inspection report.
The segment is marked. The technician knows to fly it again.
The segment is not documented. It does not appear in the report as done.

How the fleet is laid out
Illustrative layout. Drone and station counts are an example, not an offer.
Drone on the route
Line or track
Tens of kilometres beyond line of sight. Age per segment.
Second drone
The next segment
A fleet shortens the day, but every segment has its own pack.
Inspection centre
The operator's office
Sees which segments are reliable.

What we do not do in this area
Not a fault detector
AKIZU does not look for damaged masts. It says whether the segment image is valid.
Not the operator's coverage map
It shows how the network behaved on this route, not the whole network.
Not a SORA assessment
It supplies numbers. The operator and the authority do the assessment.
A pilot in this area
Long routes, changing coverage, a truthful image.
We are looking for first partners. The application is pre-filled for this area.
Other areas
Example deployments are illustrative. AKIZU is in development and does not replace a BVLOS authorisation.
In more detail
Before a meeting on inspection
A segment is finished only if its image met the target.
Bring the route and the segments where you expect coverage at altitude to be weaker. A report without that cannot mark a repeat pass.
We do not look for a damaged mast. We say whether the segment image is valid.
Bring to the meeting
- Route length.
- Flight altitude.
- Who signs today that a segment is finished.
This is not
- Fault detection.
- A certificate for the line.
- One flight as a yearly report.
