271454Z AUG 97SUBJ: RUSSIAN AVIACONVERSIA PORTABLE GPS AND GLONASS JAMMER
SYSTEM (U)

SUMMARY:

(U) CONFEX - THE RUSSIAN FIRM AVIACONVERSIA MARKETED AND DISPLAYED ITS
PORTABLE GPS AND GLONASS JAMMER AT THE MOSCOW AIR SHOW '97, 19-24 AUG 97, IN
MOSCOW, RUSSIA. THE 4-WATT JAMMER JAMS CIVILIAN AND MILITARY FREQUENCIES OF
GPS AND GLONASS UP TO A RANGE OF 200 KM. PROTOTYPE AT THE SHOW - LOOKING FOR
BUYERS.

TEXT:

1. (U) THE REPORTING OFFICER (RO) SPOKE WITH DR. OLEG ((ANTONOV)), DIRECTOR
OF AVIACONVERSIA (ADDRESS - 103009 MOSCOW, TVERSCAYA, D.27-2, OFFICE-88,
TELEPHONE/FAX +095 2995454) ABOUT THE GPS/GLONASS JAMMER AT THE MOSCOW AIR
SHOW '97, IN MOSCOW, RUSSIA. THE JAMMER SHOWN IN ENCL 1 AND 2 IS FULLY
FUNCTIONAL - THIS IS NOT A CONCEPT. DR. ANTONOV SAID THAT HIS COMPANY WAS
WITHIN A WEEK OF FINALIZING THE NEXT GENERATION GPS/GLONASS JAMMER THAT
REDUCES THE SIZE AND MASS OF THE JAMMER BY SLIGHTLY OVER 50 PERCENT. DR.
ANTONOV SAID THAT HE HAS ALREADY RECENTLY MARKETED THE JAMMER IN THE MIDDLE
EAST AND SAID HE HAS SEVERAL POTENTIAL CUSTOMERS THERE. HE DECLINED TO
ELABORATE FURTHER AS TO WHO MAY HAVE ALREADY CONTRACTED FOR HIS JAMMER. DR.
ANTONOV SAID THE SOPHISTICATION OF THE SIGNAL JAMMERS WAS BEYOND THE
TECHNICAL ABILITY OF HIS MIDDLE EASTERN CUSTOMERS. HE SAID THAT BESIDES
RUSSIA, ONLY FRANCE, THE UNITED STATES, GERMANY, ITALY, SWEDEN/NORWAY, AND
POSSIBLY ISRAEL ARE ABLE TO BUILD THESE SOPHISTICATED SIGNAL GENERATORS. TO
INSURE THE BOX WAS ACTUALLY FUNCTIONAL, THE RO ASKED FOR DR. ANTONOV TO
DEMONSTRATE THE SYSTEM. DR. ANTONOV AGREED TO AND BEGAN TO CONNECT THE POWER
SUPPLY. WHEN TH RO ASKED IF HIS JAMMING MAY INTERFERE WITH AIRCRAFT IN THE
VICINITY, DR. ANTONOV SAID THAT WHILE SOME PILOTS USE GPS AS PART OF THEIR
NAVIGATION PACKAGE, GPS IS NOT LISTED INTERNATIONALLY ANYWHERE AS AN
AIRCRAFT COMPONENT AND INDICATED ITS NAVIGATION USE CONSEQUENTLY DID NOT
NEED TO BE RESPECTED. AT THIS POINT, THE RO DID NOT WANT TO BECOME
POTENTIALLY PARTIALLY RESPONSIBLE FOR ANY AVIATION MISHAP THAT MIGHT RESULT.
INSTEAD OF TURNING ON THE JAMMER, THE RO ASKED DR. ANTONOV TO UNSCREW THE
BACK ASSEMBLY AND HEAT SINK SO THAT THE RO COULD INSPECT THE COMPONENTS. DR.
ANTONOV TOLD THE RO THAT THE JAMMER HAD TWO MODULES. THE FIRST MODULE
CONTAINED FOUR SIGNAL GENERATORS THAT INDIVIDUALLY JAMMED THE FREQUENCIES OF
CIVILIAN GPS, MILITARY GPS, CIVILIAN GLONASS, AND MILITARY GLONASS. AS DR.
ANTONOV WAS STARTING TO UNSCREW THE PLATES, THE RO KNEW THAT HE WAS LOOKING
AT A FUNCTIONAL DEVICE.

2. (U) THE GPS/GLONASS JAMMER HAS AN OUTPUT POWER OF 4 WATTS AND CAN
EFFECTIVELY DENY USE OF GPS IN AN AREA RANGING AS FAR AS 150-200 KM. DR.
ANTONOV SAID THAT HE HAS ALREADY WORKED IN CONJUNCTION WITH THE RUSSIAN
MILITARY WITH DIRECTIONAL ANTENNAS FOR HIS JAMMER SO THAT IT CAN BE USED TO
DIRECTIONALLY JAM WHILE MAINTAINING SAFE AREAS FOR FRIENDLY FORCES TO ACCESS
GPS OR GLONASS. THE COEFFICIENT OF ANTENNA AMPLIFICATION RANGES FROM 2-5,
DEPENDING ON THE TYPE OF ANTENNA USED. THE ELECTRICAL INPUT SUPPLY IS EITHER
BATTERY OR DC LINE VOLTAGE. DR. ANTONOV PRODUCED BOTH 15 V AND 6 V SUPPLIES
THAT RAN OFF OF 230 VOLTS LINE INPUT. THE JAMMER DISSIPATES 25 WATTS WHEN IN
USE AND WEIGHS BETWEEN 8-12 KG WITHOUT BATTERIES, DEPENDING ON THE
CONFIGURATION. IN THE FRONTAL VIEW OF THE JAMMER SHOWN IN BOTH ENCL 1 AND 2,
TWO KNOBS CAN BE SEEN AT THE BASE. THE LEFT KNOB IS FOR FREQUENCY
MODULATION, AND RANGES FROM 0-6 MHZ. THE RIGHT KNOB IS FOR "VELOCITY CHANGE
OF MODULATION" AND RANGES FROM 44-270 HZ. A PORTION OF THE ABOVE DATA IS
CONTAINED IN ENCL 3, WHICH IS IN RUSSIAN. THE RO HAD ENCL 3 LOOSELY
TRANSLATED, VERBALLY.

3. (U) DR. ANTONOV SAID HIS NEXT TESTING WOULD BE ON AN AIRBORNE PLATFORM,
WITH THE ASSISTANCE OF THE RUSSIAN MILITARY. HE SAID THAT, IN A PREVIOUS
TEST, FOUR TYPES OF GPS AND GLONASS DEVICES, TO INCLUDE ONE PRODUCED BY
MAGELLAN, WERE SUBJECTED TO JAMMING AT REMOTE DISTANCES AND ALL THE
NAVIGATION DEVICES FAILED IN THE FACE OF THE JAMMING. HE SAID THAT HE HAD
STRONG INDICATIONS THAT HIS TEAM, WORKING WITH THE RUSSIAN MILITARY,
SUCCESSFULLY JAMMED A DEVICE WITH P-CODE CAPABILITY. WHEN THE RO ASKED FOR
MORE DETAIL ON THIS, DR. ANTONOV WOULD NOT ELABORATE.

чисто русский подход, из подручных материалов, еще и автоантенну приладили. Нафих-то Глонас им здался его итак считай что нет . Из дальности полагаю нолик можно смело убрать.

[Werewolf]

да хрен его знает наши могут изъебнутся и еще нолик досадить

И зонд запустить и слушителем.

хорошая система GPS

"Выводы

1. Из-за сильной зависимости от простейших организованных помех в виде расстроенной несущей использование GPS в ряде случаев окажется невозможным. Причем, в обоих (гражданском и военном) каналах. При этом для глушения ни гражданского, ни военного канала знать коды ФМ-сигналов не требуется.

2. Поскольку фазоманипулированные сигналы используются во многих других системах, а помехозащищенность их к узкополосной помехе практически отсутствует, весьма актуальным является разработка метода построения системы сигналов, обладающих повышенной помехозащищенностью к ансамблю помех."
