    Terrain Aided Autonomous Navigation

    TerraFlite™ is a terrain aided autonomous navigation solution for airborne platforms in GPS absent or denied environments. It measures ground terrain features through a Radar Altimeter and correlates those features with stored Digital Terrain Elevation Data and Barometric Altimeter to provide more precise aircraft position equal to or better than GPS.

    Features

    Reduced target horizontal and vertical error with increased platform position accuracy,
    Increased situational awareness through high correlation among real world and position ased image generation,
    More precise passive obstacle warnings,
    Jam Resistant,
    GPS Independent,
    Low Cost
    High resolution DTED Level-2 terrain elevation data,
    Arrive on target in GPS absent/denied environments,
    Can be used with digital moving map, obstacle & terrain warning and auto piloting systems,
    Easy integration with airborne systems,
    Fully integrated with FocusFlite™ AS solutions
    Environment

    Support COTS processors,
    Support Windows and Unix-based operating systems,
    Certifiable to DO-178B Level-C,
    Support MIL-STD-1553B, ARINC-429, Ethernet, RS232 interfaces.

    I thought this was one of the way the cruise missile navigate.

    Looks like a weak patent, when there is prior art.

    i am not referring to that angle. Sweden has been selling stuff to Middleast/pakistan for long time and China has backdoor to all those countries. civilian industry sweden already sold off and more and more components for military products get imported. it has very small technical base and cant produce that much diversification in export products. the word diversification mean to quickly produce completely different variant when product is compromised. Is there Gripen in south africa?

    Yes, Pakistan bought EriEye, but was rejected when they asked for Gripen.
    Same for Middle East.
    What has South Africa to do with the discussion?
    They are not on the banned list.

    Only lethal weapons.

    I believe that weapons useable to quell an insurgency are blocked,
    but weapons mostly useable for defending a country are OK.
    Gripen is not sold to the Middle East, GlobalEye is OK.
    Recoilless weapons like the AT-4 would not be allowed, but ATGMs probably would be OK.
    A deal involving refurbishing ATGM in Saudi Arabia got canned because some other rules got
    circumvented by some government employeees forming a secret company for part of the deal.
    As a result, an agreement of cooperation with Saudi Arabia was cancelled, and the ATGM deal canned.

    So what’s the most likely:

    1/ FInland joins Nato & the US installs missiles
    2/ Russia attacks Finland.

    You have one hour.

    Russia aka Soviet Union has already attacked Finland, so…

    It does not matter where they got equipment at time.

    If the claim is that they only win because of US support, and no US support is to be found…

    There is another factor. Let it be called “fighting spirit”.
    German officers during the Second World War estimated it as follows:
    1. Russian
    2. Germans
    3. Englishmen
    4. Americans

    Everyone knows that Arabs are bad soldiers. And the Jews are cunning and clever

    The fighting spirit of the Finns were many times that of the Soviets during the Winter War.
    It is highly likely that any war would be with Russia as the attacker, so the Finns would be
    fighting on their home ground, so I doubt it would be different now.

    That was US fighting Egypt. In 60s US has tremendous technical edge both in equipment and training. Finland import dependent GDP is practically zero . Russia can easily establish fire control over it’s trade.

    All those Mirages, and Ouradours employed by Israel in 1967 were sold by the US?
    Maybe You are referrring to WW2 Shermans and Half-Tracks?
    US only started to sell significant amount of material to Israel in 1970.

    Potential of possible adversaries (area of the territory * population):
    Finland 1.0
    Sweden 2.38
    Russia 1336

    Gross domestic product
    Finland 1.0
    Sweden 2.16
    Russia 20.1

    The Air Force, the number of combat aircraft
    Finland 1.0 (126 pcs.)
    Sweden 2.23 (281)
    Russia 10.7 (1348 pcs.)

    F/A-18C/D surpass JAS-39 by 20% in total combat effectiveness.
    F/A-18E/F surpass JAS-39 by 85% in total combat effectiveness.

    To equalize the chances in the air war Sweden-Finland, the latter requires 70 F/A-18E/F or 33 F-35A
    To fight with Russia is senseless

    Based on Your ridiculous way of comparision, Egypts potential is 522 times that of Israel.
    Egypt still is beaten.
    I guess You compute combat effectiveness in the same manner,
    Maybe it is not a coincidence that Sweden has conquered Moscow,
    but Russia has not conquered Stockholm, LOL.

    It has taken more than just that.. the land up to the Lake Onega, Eastern Karelia or closing the blockade of Leningrad from the north..

    Finland stopped well short of Leningrad, and also stopped their offensive vs Murmansk.
    Stalin realized this, so that was the reason, they were not occupied after WW2.

    While the non-aggression pact between Germany and the Soviet Union was still in force,
    Stalin informed Hitler that Finland would get he same treatment as the Baltic states,
    so there would have been a second war anyway.

    At that time, Germany was not really trusted, and Finlands sought relations with Great Britain.
    After the fall of France, that venue did not seem realistic.

    It does not predate Nazis many years as they alone have adopted the insignia roughly in that time (symbol for Aryan race, 1920, I think).. the use of hook cross by states like Latvia or Finland is always excused in style “but oh, this is the sacred symbol of auspiciousness and has nothing to do with Nazis, whatsoever” but the fact is that all the states having used it have later aided Nazis in the WWII in one way or another.. An accident? You tell me..

    It was not an accident that Finland joined Germany.
    It was a reaction to the illegal actions of the Soviet Union in 1939.
    Finland had every right to regain their territories.

    If the Soviets had not attacked Finland in 1939, the Finns would not have joined Germany.
    They would have tried to stay out of the war.

    IOC of Swedish Gripen E is planned for 2023 and FOC a few years later (2026?). A bit tight for Finland perhaps.

    What do you mean by “only if relations stay good”? Are there any indications that relations can change?

    Sweden and Finland are discussing a much tighter cooperation on defense.

    Force protection for an AWACS becomes impossible when the defender only has Gen 4 jets against a Gen 5 adversary. The AWACS/Gen 4s can only detect the Gen 5 at half of the Gen 5’s missile range. The Gen 5 flight, launching from beyond detection range, simply wipes out the Gen 4 defenders in a BVR salvo and chases down the AWACS.

    Unless the AWACS detects the Gen 5 aircraft first, and provides targetting information to the Gen 4 fighter
    which fires its missile, before the Gen 5 aircraft detects the Gen 4 aircraft.

    IIRC the radar of the E-3 is S-band, & AFAIK neither it nor the Erieye has difficulty in tracking fighters. The Northrop Grumman MESA radar works on L-band, i.e. lower frequency, & Australia, S. Korea & Turkey must believe it can track fighters, as they’ve bought AEW aircraft equipped with it.

    If I understand things correctly, they remove a filter stage which typically ignores low RCS echos,
    and then try to detect which of those echoes behave like an aircraft, so you have to process many more
    potential targets and require much much higher performance processing for stealth detection to work.
