You use a clock. You take a bearing on a signal source A from position B and then move a known distance B over a known time, take another bearing, solve the bearing angles to your baseline course and then you have a range solution. That was how the launch aircraft (PB4) knew the Japanese destroyer was in range for a bearing only BAT launch at that ship.   

 

 

The way to defeat that method if you used an RWR instead of your eyes, a gunsight telescope and calipers and a scaled graphed plotting board is to slide and warble your radio beam and mask/mimic it with a parallel decoy transmitter so that you have a smear bearing so that when the receiver array tries to solve for range by solving the baseline angles, well guess what? NO SOLUTION POSSIBLE.

 

If you can't get the ;precise angles, you can't get the true range. It isn't hard spoof for range. And of course if you don't have the clocks and he does, he can defeat your amplitude compression efforts by adding his own compression component into his own sigbal to generate a false time pulse component to his signal built in. Makes his signal appear closer/farther than it is at the same time. Whuch solution do you use? False range data. Do you bearing launch at a surface target at a 1 degree spread at 70,000 meters knowing that you have a 1400 meter bearing error side component even if your range estimate is within the 10 percent ladder? Well?  That is a big error.for a blind lob launch.  The guided weapon will use an active seeker that will communicate with the launch aircraft and will self correct via GCU or be steered into coincident merge from the launch aircraft's onboard ACTIVE sensors painting the target or the pilot himself looking at the target and flying the bomb into the target. Something has to look at the sigbal and chase it during endgame to point the ordnance. THAT us why i rekect all of MK's explanations for what he meant. its easy to explain, there should have been no confusion at all, and no appeals to some bias as an attempt to claim to say I didn't understand what he meant. I knew exactly what he said, read it back, and showed where it was wrong and WHY.

 

 

Just like the electromagnets that the Cern  proton-anti-proton collider come from thr same AMERICAN suppliers who supply Fermi Lab and who will probably supply ITER with their confinement magnets as well.

 

The French don't have the clocks. WE do. We sell them.

 

   

 

 

 

 

 

 

     

 

Thats certainly the way i was thinking,  some sort of active terminal guidance or a definite gps position would be required to guarantee a direct hit

If after all that you are trying to say that the Rafale can not use SPECTRA to estimate the bearing and the range to geolocate an emitter (within a margin for error, of course, just like always for all such determinations by anybody), then you are wrong.

I said the margin of error was too large to aim a weapon in real time, without active terminal guidance IN THE WEAPON or external guidance from the launch aircraft or some support system telemetered into the weapon at the ranges some claimed.   

 

Unguided free swimming torpedoes usually missed single target tracks at ranges beyond 4000-6000 meters because the relative velocity difference between  torpedo and target was small, and time to evade by simple turn away off the predicted target track was huge. Bearing only launch at flocks of target tracks with a slow short endurance weapon that cannot turn to chase leads to 10% weapon PK being considered a good outcome percentage by WW II standards. Submarine/freighter engagements were ~1000-3000 meters with torpedo run times of anywhere from 50-180 seconds. That situation wasn't "Destination Tokyo". Even on the surface with with radar, it could take up to an hour to maneuver the boat set up a target track firing solution (merge tracks and point at the enemy close enough and with enough lead angle to establish a weapon intercept even if you curved the fish's track to compensate lead angle) and almost ten minutes to reload and properly prepare a set of tubes if you missed with your first attempt. Too often the freighter convoy simply zagged away after the fish were in the water.    

 

 

 

 

 

 

Oh, okay, that's good, and in that case you, MK, and I are all in agreement, as we each have said here.  It's a shame that BW couldn't keep a more reasonable approach to his posting style and avoid finally getting canned (again?), and that FS hasn't chimed in lately (one can only hope he got the cyberaxe, too, but that seems unlikely), because I would certainly have liked for them to absorb this fact regarding the Rafale's degree of capability to perform DEAD--which is certainly less than they were claiming.

 

 

I come back from the WE and an hard week of work and I found usual bullsh**t

Again I provide facts here and links to debunk lies...

There is now a competitor of Temex in Les Ulis

Orolia?s headquarters are located in Les Ulis, (France).

SpectraTime, a company of the Orolia Group (NYSE Alternext Paris ?
FR0010501015 ? ALORO), today announced the award of a contract valued at 1.8 M? to supply six
Rubidium Space Clocks for scientific Earth observation satellites. With this new contract, SpectraTime
confirms its position as the world-leading supplier of space atomic clocks for scientific and navigation
applications.

Orolia is a high-technology group specialized in precise Positioning, Navigation and Timing. Orolia provides high-precision electronics equipments that generate, distribute, measure and process the high-precision Time & Frequency signals that Critical Operations use to detect, trace, control, analyze or synchronize time and location-critical events.
High-precision timing, positioning and synchronization solutions are vital for critical applications in growing markets such as Defense, Public Safety, and Telecom & Broadcasting in land, maritime, air or space environments. Since 2006, the Orolia group has been able to establish itself as one of the leaders in PNT solutions at a global level through four companies:

Now to Warpig:

Le deuxième jour de l?exercice, le « Comao » devait notamment s?attaquer à un site de missiles sol-air. En jouant des capacités interférométriques de Spectra, de la puissance de l?OSF et de la transmission de données par L16, les Rafale ont pu détecter, identifier et détruire le site à longue distance en tirant « virtuellement » des missiles AASM (3).

 

What it says, is that Rafale use Spectra and Link 16 and OSF (or possible radar in bad weather) to locate SAM and destroy them with an AASM at long range

Its OSF is precise enough to give a very precise bearing once SAM battery detected by Spectra.

Use of link 16 suggest that Rafale cooperated so it could be for triangulation.
