Has there been any news about Fulmar 500?

even on Aselsan web page for Fulmar 500 there is an Akıncı picture Since Akıncı now has Murad option

My first guess would be Frontal Murad AESA was prefered instead of a under belly Fulmar 500 and under belly section is left for heavy ammunition indeed forntal AESA has its obvious advantages for Akıncı.

Essentially, MURAD does not replace FULMAR. One is optimized for airborne search&track that works on higher refresh ratea and another is optimized for SAR/MTI data processing which is crucial for ASW / ASuW target acquisition and classification.

MURAD may not bear the same processing unit load when it comes to SAR, yes it has that mode but it is not the primary duty of it.

Also we should keep the search patterns in mind - with FULMAR the airborne asset may go into circle pattern or line search patterns and keep a focus on a zone, yet on AESA it has to go through 8 figure occassionally losing sight of the target zone. One consumes higher amount of fuel to maneuver.

The Fulmar-500 Radar is in Terms of it's Capabillities compareable with the AN/ZPY-3 Radar which is in use by the MQ-4 Triton Drone of the US Navy. We have an urgent need for an high Altitude ISR UAV, in my Opinion Akinci is not a proper Plattform to conduct such a Task. We could need an UAV comparable to the chinese CH-7 with Stealth Charateristics, which reaches an Altitude more than 50.000 Feet, have a long Endurance and which is equippt with Fulmar-500. This would be the best Case.

Are they using fiber optic?

I don't think so. Maybe EHSIM can offer it as an option if customer wants it.

Aselflir 600 , just took the photos of Selanik from Gokceada. 225 km distance, what a marvelous achievement. Above all else Kara Vlahs going to have the convulsions, and that is very pleasant thing for me.

 

[Yasar_TR]

The 225km range is especially important.
It is the distance from our waters west of Cesme to Athens.

R (C) : 223318 m R ( C ) stands for Range calculated ......distance is not directly measured one but calcutated one..... by itself not exact target coordinates for weapon grade fire control solution.... But I am sure we already have the exact coordinates for the strategic targets so we can watch them burn

 

[IC3M@N FX]

Is it possible to continuously track or "lock onto" a large, stationary target (e.g. bases, ports or large ships) over distances of 200+ km or more without a laser designator in order to guide even low-cost intelligence ammunition precisely to the target – even under heavy jamming?
The background to this is to create cost-effective attack options without relying on additional sensor nodes or navigation systems such as GPS/INS, as these can be deliberately jammed or falsified. At the same time, TERCOM is considered technically cost-intensive.

And even if it isn't weapon grade fire solution it is more than enough to direct loitering munitions with their own guidance sytems like Kemankeş and Kargı(hopefully one day) towards correct location. Or to direct low attitude observation drones to relevant location for more precise tracking. Being able to detect mobile platforms like air defence, electronic support vehicles, artillery etc from such long distance is insanely valuable even if it isn't directly actionable

Just speculation, as we know very well, that defense companies will never show the full capabilities. Means, it is very likely that AselFlir-600 could have wider range.

 

[TheInsider]

Aselflir-600 has accurate geo-location capability. No matter the distance, Aselflir can provide a targeting solution for fixed targets.

 

[Quasar]

This is already covered ...........what C in R ( C ) stands for is a calculation...... this calculatons involves EO/IR line of sight (LOS) angle i.e azimuth and elevation angles, Platform GPS/INS position and slant range estimation.

''No matter the distance''? Yes and No! The calculation is distance independent, but the resulting error is not!!!

Even in an ordinary day and under normai circumstances Error stack problem occures i.e stacking of LOS angular error (microradians), Lateral position error, INS drift, Platform attitude error even with high-grade tactical INS or GPS.... And Error stack problem is not very distance friendly since even very minimal errors ends up with significant results with distance, this does not mean the imperfection of Aselfilir 600 but simple physics.

ASELFLIR has exceptional and excellent ISR quality and perfect to cue the network..... this is simply the essence of it

With Ahmet Akyol's words: ''ASELFLIR-600 provides Turkey's UAVs and attack platforms with strategic depth target detection and identification capabilities.''

This is wrong. You first have to learn how geo-location in Aselflir-600 works. This is not how it works. This is how Aselflir-300T works. Aselflir has sensor fusion based advanced geo-locating capability.
*Error stack problems occur.
It does not occur because it is not how it works.

Welcome to 21st century where we have sensor fusion, where drones can cruise without GPS data, where we can get every kind of positional data through platforms' own (jam resistant GPS/INS sensors,altimeters etc) sensors, through datalinks from ground or other aircraft, through satcom, where we have highly detailed(1cm to 1m level) maps on board platforms so that we can compare our relative position to what we see. You see that hill in the picture? Aselflir-600 knows the exact coordinates of that hill from 225km away and Aselflir knows the coordinates of a possible target (an object with a size similar to a MBT), with an error rate of 3 to 4 meters.

Concerning the real distinction between ASELFLIR-300T and ASELFLIR-600

The improvement is not that ASELFLIR-600 “doesn’t have error stacks'' The real advances are: Multi-frame temporal fusion, Terrain-aided navigation, Cooperative cueing and updates, Better attitude knowledge and stabilization and Smarter uncertainty management... Error propagation is controlled not eliminated.

ASELFLIR-600 significantly reduces geolocation uncertainty through multi-source sensor fusion, but it remains bounded by geometry, observability, and physics. Errors are managed probabilistically, not eliminated.

rest of your post is word salad or information and concepts used without their true and full connctions to their contextes or their true relations with each other.

Aselflir can provide a targeting solution for an MBT sized target with an error of 3-4 meters over 200 km (this is not open source knowledge). Rest is not important. Your argument was Aselflir-600 can't do that. Now you moved the goalpost to where I stand, good for you. Aselsan actively markets Aselflir-600 as a "superior" solution to Wescam or other producers' products in the same class.


Here you can listen Ahmet Akyol tells as Aselflir-600 is one step ahead from the rest. It is not because of image quality/range performance. MX-25 offers similar capability in that regard.
