Still from another new Saab movie called "Ambush" which I posted on a while back
Director Patric Ullaeus and the Revolver Film Company has started to work on yet another film for SAAB's fighter jet GRIPEN.
Let's hope it's even better than Controlling The Battlefield.
[SIZE="4"]AESA:s need fast processors[/SIZE]
Already back in 2001 Ericsson had developed a processing unit around 100-times faster than now operational systems in 2008.
With all the forum talk about AESA radars these days I pulled out this info on a late 1990s research project by Ericsson Microwave Systems (Now Saab) and Hamstad Uni on a new signal processing system to be used with the ever more demanding AESA sensors.
Taking in and processing the enourmous amount of data is a key challenge to deliver operational AESA radars with added capabilities. Ericsson who produced the first operational airborn AESA found that there were no processors on the market fast enough for the next generation systems.
And not even fast enough to be used as nodes in a scaled system so they developed a Application Specific Integrated Circuit (ASIC) on which processor arrays would be placed. The ASICS were then interconnected on a board that would go into a processing box to be used with a AESA sensor.
What they came up with in 2001 was a ASIC containing 25 GFLOPS of processing power, each board had then 8 ASICS and each box had 5 boards. Totalling over 1 TFLOPS of power.
Not to be viewed as what will be in Gripen or what's even in the research labs today. It's just a piece of information on research at the turn of the century. [IMG]http://i14.*******.com/4l7a26cdotgif[/IMG]
We have designed a signal processing system that meets the requirements, including tight size and power constraints, from future multichannel fighter radar systems.

Ps. Dr. Freud, if you decide to rip off this post like some other ones here at least be a gentleman and give credits when you post on other forums.

wait, what did i miss about the Dr Freud thing?
lol, i will give you credit from now on, i just didnt know if i were allowed to link to another forum.
otoh its a credit in itself to you that i cite you, i wouldnt post it if i thought it was crap. i didnt pretend it was my own stuff, i said "someone"
next time i refer to signatory.
morboute i cited signatory's exellent info/calc. on range on JSF/JAS/EF page 13 in this thread.

Another thing signatory: i feel that gripens radar range is short compared to Su-27+ :why not rip out the radar receiver in front of gripen, cram in as powerful transmitter as possible, and spread out the receivers on pylons, wingtips, etc ?
I also wonder if more computing power can negate the advantages of VLO by better analyze the few photons that still will come right back to the plane ?

It was these most recently that looked a bit "fishy"..
Your other questions on radar is not really something I can guess on.. but I know low signal processing power has been a obstacle not just for the AESA development but also the IRST sensoring as to get usable signals at long distances. In the future we're likely to see the AESA sensorfuse with a IRST to provide a scan and track that is very effective against 'stealthy' targets at a fairly decent distance.. we could probably learn together with Italians and French in this regard. There's also the electro-magnetical field to think about. We'll see what the brains come up with
ISR, Intelligence, Surveillance and Reconnaissance
SPK Spanings Kapsel (Recon pod)
Another Swedish only article on the growing Recon capabilities on Gripens in the SwAF.
There's too much to translate, it talks about the methods for recon, but the part about the Electro-Magnetical spectrum is worth the effort so here goes...
(These photos came with the article but it doesn't actually say if it's all from Gripens...)The electromagnetical spectrum. Wavelengths from millimeter to meter
In our world, regardless of peace or conflict, we're surrounded by electromagnetical radiation over a large span of wavelengths. Other than visible light and InfraRed there's also detectable radiation used for things like radio traffic. In the military world there's a large amount of emitters used for communication, detection, range finding or jamming.
In JAS 39 there is a system of antennas that already on the ground start to detect, positioning and identify these kinds of signals. In real-time the pilot can conduct a analysis of his surroundings without making himself visible.
By passive sensors the aircraft EWS (Electronic Warfare System, see pic below) begin to listen already when the jet is on the ground. Signals are registered and those signals previously identified as friend or foe is presented to the pilot. During the entire sortie the pilot can analyse and distribute information generated by the EWS. Other than this passive tracking the pilot has a very advanced active emitter at his disposal.

Gripen with LDP Laser Designator Pod
Today the Vice President of Colombia Mr. Francisco Santos Calderón will arrive for a five day visit here in Sweden. He was most recently here in November.
This visit was supposed to be announced on Sunday but One paper found out and and also claim there's ongoing discussions for a JAS Gripen sale to the country which is even supposed to be the reason for this visit. Several meetings with Saab and Ericsson is said to be planned.
I can't really judge this report... it's a fairly serious news site though.
On Tuesday he is due to meet with Deputy Prime Minister Maud Olofsson which is basically the only top minister left in the country that week. (The Prime Minister and his delegation will be in China and the Defence Minister among others will be in the USA) There's also a state visit from Luxemburg that day...
If Colombia has a imminent need for additional fighters Sweden can deliver JAS 39A and 39B jets almost instantly from a planned surplus inventory. Conversion training is the main delaying factor. The latest version 39C and 39D models would likely take roughly 2 years before delivery.
This thread about Colombia buying Israeli Kfir would probably be the best to post in for further speculation.
Information about a industrial networking meeting in North-Norway scheduled for Monday with Saab.

[SIZE="4"]Gripen User Group [/SIZE]
A GUG meeting was held April 8-10 in the Czech Republic.
The main reason to constitute a Gripen User’s Group for current and future operators of the Gripen aircraft is to initiate a closer collaboration between the Gripen users concerning efficiency in both operational and technical aspects.

Dalekovod, Podravka and Ericsson Nikola Tesla have signed the memorandum of understanding with Swedish SAAB, as a part of Sweden’s offer for delivering 12 military aircrafts to Croatia. This is the first step towards signing the offset agreement, but it is not binding to any party.
At the press briefing on Thursday, representatives of SAAB, manufacturer of Gripen fighter planes, said they had established contacts with over 20 Croatian companies so far and that their offset offer could include over 100 companies. According to SAAB sales and marketing director Bob Kemp, Dalekovod could increase its export to Sweden, where there is a growing energy demand, while Podravka, as well as Croatia overall, has great capacities in food production.
Kemp announced that SAAB with its partners, including Volvo, Aero Corporation and General Electric, would offer offset with the goal of long term employment, investment, knowledge transfer and growth of export, and Croatian Government will be able to choose which of these it wants.

I like this idea about Gripen User Group. Each can shares the tactic and technic that each member developed. Like the Chinese said, Two heads are always better than one head.
But now we've got 5 heads.
PS. I guess Thai delegate is not join. This round of meeting is too early for Thailand. Hope we can join in the next meeting.
I hope Colombia can join the Gripen user group.We already have a defence agreement with Thailand so it would be the obvious choice.
Althought they're great planes, compared to the Sukhois's, Gripens are like flies in the sky waiting to be swatted.
Or, perhaps, maybe ... hmm I dunno... NOT?
Regardless, I'm sure your threadcrapping comment keeps you warm at night, now that all us Gripen boys know what's what.
This being the Gripen NEWS thread and all.
Good day to you, sir.
