I wonder during which segment of approach/landing the AI gets used (only on final?). It looks like only image recognition, so how does bad weather affect it?
Automatic carrier landing was already possible decades ago without AI.

How else would it work? The image sensors compare the pre-stored image parameters, and internally, the GPS and INS systems are probably recalibrated relative to the position of the ship and the drone for validation.

Image from the ship = true
GPS signal from the ship, i.e. position = true
Handshake for automatic landing = true

The automatic landing system works like a tractor beam (as in Star Trek; unfortunately, I don't have a better comparison to describe it).
A handshake takes place between the drone and the ship's antenna, i.e., the sensor. The drone and the ship's antenna + sensor system then control the drone and adjust its speed and angle of ascent during landing.
It works the same way in bad weather condition or at night: as soon as the drone has located the ship using night vision and GPS, the automatic landing system in the ship takes over the rest via the handshake.

The image itself, including the base plane in the ship, therefore serves only as a reference; the guide beam from the ship together with the drone does the rest.

Night vision is affected by bad weather too. And how would thermal vision work without heating the significant part of the deck, or else the whole deck would look like the same?
Also i am only talking about the AI part, the other part is already in the link i have provided.

They are using COTS, OpenCV, YOLO.. definitely not military grade, nor "reliable". Even the interface is off the shelf.

• Possibly not using the TACAN on the ship, but LOS for retrieving ships heading, speed, position,
• Definitely not using the Precision Approach Radar on the ship,
• Using ML onboard (UAV) for lateral corrections,
• Using ML onboard (UAV) for vertical corrections,
• Last two information is somehow correlated on the UAV for estimation of the range, also the runway helps for this.

Man, i don't know.

 

[TheInsider]

UAVs that use military grade components crashes more frequently than TB-2 per flight hours. There is no doubt that there is a secret sauce.
The finished product will use precision approach radar(OKIS), TACAN, and ILS on top of AI based landing system. Baykar is optimizing its AI system to land aircraft without those inputs. Baykar will market TB3 as the only UAV that needs no landing help to land on short runway ships.

Man if they do that just yolo and opencv that would be funny. You can calculate distance from image with few assumptions, but making it precise is difficult. If you have altitude and you know size of a reference object you could calculate distance

When the tests are carried out whereby TB3 lands automatically on to a wobbly TCG Anadolu with some side winds, then we will be more confident about safe landing.

All 115+ tests have been carried out on a ship that is really steady.

One need to consider the fact that even a 100thousand ton US carrier has to abandon take off and landing under certain harsh weather conditions. Yet ships with shorter runways that employ F35Bs have more leeway in that respect. Their window of operation capability under severe weather conditions is much wider due to vertical landing option..

A squadron of F35Bs on the TCG Anadolu will be a priceless addition if we could have them. It may even be the reason to abandon MUGEM and build a second LHD.

As the saying goes :
” Where there are no sheep, the next best thing is a goat”

Having said that, use of the LHD as a UAV carrier too is a novel idea if we can make it work in adverse weather conditions too. (To a tolerable extent)

 

[Zafer]

TB3 will probably do adverse weather test sorties on TCG Anadolu after every other test is done as it will be the riskiest. Also full payload and adverse weather means the riskiest. I think TB3 should handle sea state 4 already and be looking at sea state 5.

They haven't tested above sea state 2, yet, the ship has little to no motion until sea state 4.

Well, it is not me but they have displayed screens and it highly resembles open source libraries. They must have figured distance through image processing at the final approach by analysis of the runway.

They don't seem to integrate PAR, at all. You won't need any image processing with PAR.

 

[Zafer]

I see sea state 3 at least at later sorties; breaking waves with white foam is no less then state 3. A state 5 sorti should be achievable without much risk. I wonder how much weather the ship will risk sailing but the TB3 can not fly. Like if the ship can sail at sea state 6 but TB3 can fly at SS 4 max then it is 2 SS difference. But if TB3 can fly at SS 5 then it is just one SS difference. I wonder if they will test the plane to see how much weather it can take at the cost of causing some accidents. They do it in aviation and fly planes until they break. I think I have sailed at SS 6 and maybe even touched SS 7 in my cargo ship days.

In this latest video I see some sea state 4 but we still need to see sea state 5 to chill.

AFAIK even most of frigate warships are not combat operational at 5 seastate. Just survive mode.

Aircraft Carrier Flight Operations – Up to What Sea State?

Modern nuclear-powered aircraft carriers (e.g., Nimitz-class, Ford-class – USA):

Typically capable of conducting flight operations up to Sea State 5 (about 4 meters wave height).

At Sea State 6 or higher, flight operations are usually suspended or highly restricted, due to:

Increased ship movement (roll and pitch), making takeoff and landing dangerous.

Difficulty in maintaining optimal wind alignment for launch and recovery.



Lighter or STOBAR-type carriers (Short Take-Off But Arrested Recovery – e.g., Russia’s Admiral Kuznetsov):

Usually effective up to Sea State 4.

At higher sea states, deck motion becomes too severe for safe aircraft operations.




---




In higher sea states, it becomes difficult to maintain a steady position.

The flight deck can pitch and roll dangerously, making both launch and recovery operations risky.
Considering flight deck structure of TCG Anadolu, 5SS is challenge.

 

[Yasar_TR]

Sea State conditions are assessed by an experienced and trained marine observer via actually measuring and by using instruments like electronic weather buoys to measure wave height and wave radar or remote sensing satellites that can assess wave height as well as degree of spray which constitutes part of the measurement process. (Not by catching a glimpse of a bit of water in a video)

Carrier operational limit is Sea State 5. But this is for a large and heavier carrier. Larger, heavier carriers generally experience less motion in rough seas, allowing for more consistent flight operations and reduced operational limitations. Smaller ships, on the other hand, are more susceptible to the effects of sea state, leading to more frequent disruptions in their ability to launch and recover aircraft

Sea state is characterised by wave height, wave period, and few other factors like wind speed which impacts a ship's motion in all three dimensions. Sea State is measured by taking all these factors in to consideration.

A 27000 ton LHD and a 100000ton super carrier will have very different sea state tolerances if they are both used for same type of carrier operations. (Also it has to be remembered that one is essentially designed to be an Amphibious Assault Vessel, where as the Carrier’s design is such that it is engineered for specifically to withstand rough seas. It has big electronically controlled gyroscopes and ballast tanks that are no match for those used in smaller ships. )

 

[Yasar_TR]

Sea states have been traditionally judged by visual clues. That's why in the video often parts showing a flag flying and an empty stretch of water showing waves and sometimes both included as much as possible while no instrument is shown surprisingly. Metering by instruments only adds precision to the judgement. So you can very well judge sea state by visual clues in a video. Please stop disrespecting members and start showing your way of judging what sea state the ship is operating in; oh yes there is non. A yes sea states is a range of values not a single value metered by an instrument.

First of all you can not tell me that I am disrespecting any member. I am not.
I don’t need to agree with what you write. Especially when it is illogical and petty.

Sea state conditions for a ship can be determined through a combination of visual observations by experienced personnel, instrumental measurements using weather buoys and wave radar, and remote sensing satellites.
Unquote.

Have you done any of that to come to a conclusion of sea state 4?

Please read below article. Especially this paragraph:

quote

How to determine the sea state?​

The simplest way is through visual observation by experienced seafarers.

In addition, specialized observation ships carry out sea state observations, including water temperature, salinity, chemical composition, marine pollutants, marine life, ocean currents, and other parameters from the surface to the deep layers.

Nowadays, instruments such as meteorological buoys, wave radars, or remote sensing satellites can be used to assess sea state. For example, modern autonomous underwater vehicles (AUVs) can make accurate measurements and sea state forecasts in complex ocean environments.

It is worth mentioning that sea state can be quickly judged based on the actual ocean conditions, but we cannot quickly determine the wind and wave conditions on the sea surface according to the Beaufort wind scale. Wind scale cannot fully represent the sea state, and in windy conditions, this state may take several hours to develop.
