Les Transmissions des FAR

Rappel du premier message :

salut tt le monde je suis nouveau sur ce forum en tant qu membre mais ancien en tant que visiteur j'ai toujours remarquer qu'il y a une absence totale des transmissions ds le forum alors j'ouvre ce sujet pour mes amis transmetteurs et pour ts ceux concernés par l'arme des transmissions des FAR alors à vos claviers...
merci pour votre efforts ds ce magnifique forum...

Avez vous les capacitès de brouiller des comm ennemies ? ou de les écouter ?

Biensur que si : ça s'appelle la guerre électronique et la veille éléctronique et pour vous mettre sur le coup il faut souligner que l'ex président mauritanien avait été sauvé de deux atentat de coup d'état grace au grande oreille de l'arme des transmissions et pour la troisième ..........!!!!! je sais plus ...

c'est quoi la couleur des épaulettes des sous-off et off de la Transmission, je crois que c'est violet, n'est ce pas ?

Durant la crise du rocher Leila, il parait que les espagnols avec accès à nos com. et savait exactement se que nous faisions ? Quand est il de nos écoutes ?

pour vous Mr : MoroccanWing
la couleur est effectivement le violet et pour Mr Interceptor : j'ai déjà expliquer que pendant la crise du rochet les espagnol ont ecouter un patrouilleur marocain " des communication routines " pour l'écoute il faut savoir que l'écoute est une filiaire indispensable pour l'arme des transmissions relis les messages de ce sujet et tu trouvera des réponse;;;

Oui j'ai retrouvé le message !
Désolé j'avais pas vu, merci pour les infos et bienvenue sur le forum !

une station FHN et en même temps peut servir d'atelier mobile

Oui merci c'est du bon matos ?

il est basé sur une chaîne hertzienne d'oujda à agadir et qu'on envisage de prolonger à guelmim.. cette chaine et d'un débit ( vous ne rêvez pas ) qui atteint 155 Mb/s et au niveau des ville une couverture wireless de 12Mb/s sur un rayon de 20 km et de gigantesques serveur de messagerie et de voix IP ( central tph) sans oublier les liaison de backup et la multitude de service offert: vidéoconférence .. intranet .. fax ..assistance à distance etc..

le 155Mbits/s est realisable grace au SDH STM-1, n'est ce pas ?

sinon est ce que le SONET OC-3 (fibre optique) est aussi utilise?

Effectivement c'est le SDH-STM1 qui est utilisé pour notre chaine hertzienne mais pas la fibre optique c'est trés coûteux, pour cela l'utilisation de la F.O est reserver pour relier les installlations distantes des sites regionaux ( cas d'agadir ) entre elles.... et de plus la F.O c'est un peu fragile,, pour le SDH c'est mieux adapté à la topographie de notre pays ( longues distances séparrant les différents sites ).

merci Rad00v.

j'ai une autre question: est ce que le RASIT est manipulé par les hommes des transmissions ?

Oui c'est vrai car les Radars de surveillance des frontières sont tous sous la responsabilité des Transmissions;

Morocco orders SINCGARS
Signal, Oct 1999

Several hundred single channel ground and airborne radio system (SINCGARS) radios with support equipment will be delivered to Morocco's government beginning in April 2000. The Moroccan government ordered the combat network radios to modernize its tactical communications.

The systems evolved from the U.S. Army advanced systems improvement program, the service's latest SINCGARS (SIGNAL, March, page 33). The radios can be easily upgraded for future use and offer new waveform and algorithms for improved voice and retransmit operations.

ITT Industries, White Plains, New York, will provide the radios.

Background

After Vietnam there were a number of lessons learned regarding the PRC-25, PRC-77 (and their vehicular versions) and the VRC-12 Series radios which led to the Single Channel Ground and Airborne Radio System (SINCGARS) concept for the next generation squad radio.

Citation :

Frequency Hopping (FH)

A major new capability is the ability of the SINCGARS radios to frequency hop covering the 30 to 87.975 MHz band in 2,320 channels. This is not done as a Transmission Encryption security measure, like is provided by the KY-57, but to prevent jamming and direction finding. The PRC-25 & PRC-77 are susceptible to squelch capture jamming since they are single frequency at a
radios. The 225 to 400 MHz aircraft band radios now use Have Quick which is a similar frequency hopping scheme for the same reason.

DESCRIPTION

SINCGARS-V (AN/ARC-201) is a single-channel, jam-resistant, very high frequency (VHF) radio for multi-service, tactical communication that transmits and receives voice, tactical data and record traffic messages. It replaces the AN/PRC-77 and VRC-12 series radios and is the primary means of command and control for infantry, armor and artillery units and is operable with NATO equipment. The modular system comes in man-carried, vehicular and airborne versions that replaced manpack, vehicular and airborne radios (see Variants below).

Each SINCGARS variant except the airborne unit is based on the RT-1523(C)/U receiver/transmitter. Adding a battery pack and antenna creates the manpack. In addition to voice, the RT-1523 is capable of transmitting facsimile, teletype and binary Frequency Shift Keying (FSK). An internal digital data transmission rate adapter allows SINCGARS to transfer at bit-per-second (bps) rates ranging from 600 to 16,000 bps. Jamming is countered by hopping 100 times per second through 2,320 available frequencies. Six single-channel presets (plus manual and cue channels) are programmable as are six frequency-hopping net presets. An integrated communication security (ICOM) module with output in either plain or cipher text was added to the radio in May 1988 and fitted in units procured after 1990.

In June 1992, ITT and GTE teamed to begin development of the integrated data transport system (IDTS), which ties SINCGARS more closely to the mobile subscriber equipment (MSE) system by standardizing data transfer.

Although the systems appear similar, the General Dynamics-Tadiran second-source offering is based on the Tadiran CNR-900 series already in Israeli service.

The AN/ARC-201(V) airborne variant offers similar capabilities, but does not have an ICOM embedded in the receiver. Its cross-section is more square in shape to fit into aircraft instrument panels or radio racks. (See separate database entry.)

STATUS

Initial Operational Capability (IOC) in 1988. Requirement issued in 1974, first competition held in 1976. Fast-frequency-hop (FFH) version (2,000 hops/sec) canceled in December 1981.

Contract for $53.8 million won by ITT Aerospace Optical Division in December 1983. In addition, four priced options were offered which totaled $334.3 million. In March 1992, a $225 million contract for 17,000 radios was awarded to ITT.

The U.S. Army requirement set by Defense Acquisition Board (DAB) in 1991 was 150,000 radios, a figure that rose to at least 213,000 radios in 1993. The Marine Corps requirement is 25,390 radios, all of which are third-generation systems. More than 142,000 were delivered by 1996, of which ITT had manufactured more than 100,000. All deliveries from 1996 on are System Improvement Plan (SIP)-level sets.

General Dynamics Electronic Systems and Tadiran of Israel combined to win a second source contract for $22.1 million in July 1988. Tadiran also had three options worth $169.2 million. In February 1995, General Dynamics received a second source contract to produce over 15,000 SINCGARS radio and associated equipment. GD in turn has subcontracted $62.5 million of this work to Talla-Com (Tallahassee Communications Industries) a U.S. subsidiary of Tadiran.

In 1993, Morocco ordered 225 ITT-built SINCGARS for an estimated $5.2 million.

Annual dual-source limited competition began in FY94, with an award in April 1994 of 17,053 units to ITT and 11,369 units to General Dynamics.

In April of 1996, ITT and GD split a US$260.8 million order for SINCGARS. ITT received US$153.8 million and GD US$107 million. In May of 1996, ITT received a US$33.5 million contract for SINCGARS for installation into the AH-64D Apache Longbow and OH-58D Kiowa helicopters.

During the FY 94-97, period annual acquisition of SINCGARS was about 26,000 units. Army plans for post-FY97 were to reduce acquisition to about 10,000 units annually. U.S. Army acquisition objective is 238,970 radios (230,348 ground radios).

In October of 2004, the Army placed a $113 million order for 20,000 advanced SINCGARS radios.

In November of 2004, the Army awarded ITT a seven-year $2.5 billion omnibus contract to provide SINCGARS radios, support and spares to U.S. and allied forces worldwide. An initial order worth $49.5 million was part of the deal.

In 2004, the Communications Electronics Research, Development and Engineering Center developed a process that allows pictures from a commercial digital camera to be transmitted over the SINCGARS system.

The Army ordered 73,000 SINCGAR radios in June of 2005, including both vehicle and manpack versions, under a $478 million contract that was derived from the 2004 omnibus deal.

In December of 2005, Australia ordered several hundred SINCGARS ASIP systems under a $4.6 million contract.

In March of 2006, the Army placed a $407 million order for 60,000 ground and 458 airborne SINCGARS systems, under the November 2004 omnibus contract with ITT.

A $23.5 million order for 2,500 SINCGARS ASIP radios was placed in April of 2006.

In October of 2006, the Army placed five orders totaling $239.2 million for 32,000 radios, power amplifiers and spare parts. The radios include "hooks" for the SideHat expansion module.

Harris wins North African military radio contract



Written by Oscar Nkala, Wednesday, 13 April 2016

Harris Corporation has received an $11 million order from a North African nation to supply its Falcon III multiband, multimission radios as part of an ongoing force modernization programme.

The contract also involves the supply of spares, installation kits and continental U.S. unit-level test equipment and training. The customer will receive thousands of RF-7800H-MP wide-band tactical man-pack radios, which has the capacity to deliver expanded data capabilities in long-range and Beyond-Line-Of-Sight (BLOS) environments, Harris said.

The customer will also receive the RF-7850M-HH multi-band networking hand-held radio, which offers wide-band communications and mobile, ad-hoc networking along with legacy narrow-band waveforms as well as the RF-7800V-HH VHF Combat Net Radio (CNR).

“Harris’ Falcon III radios will support the customer’s need for simultaneous, secure voice and high-bandwidth data across a wide range of military missions. Our strong presence in the region, coupled with our ongoing investment in advancing Falcon solutions, enables us to transition customers from their legacy, voice-dominated tactical radios to networked wide-band tactical radios," said Harris Communication Systems President Chris Young.

Harris was earlier awarded a $20,116,679 firm-fixed-price, foreign military sales contract for radios, spares, installation kits, and continental U.S. unit-level test equipment training to Morocco, Kuwait, and Qatar, according to the US Federal Business Opportunities website, which added that work will be completed in February 2021.

Given the fact that the North African contract was announced shortly after the Morocco, Kuwait and Qatar contract, it is likely that the $11 million order is for Morocco’s armed forces.
