The Brazilian army is receiving the first prototypes of the Elbit systems software defined radio (SDR). According to the plan the army will receive 16 prototypes of the RDS Defesa systems
Company sources say that now, the expectation is for the acquisition of an initial batch for distribution among the forces and the development of doctrine for the vehicular version of the system.
Software-Defined Radio (RDS Defesa) Project, a solution that is part of the strategic programs of the Ministry of Defense. The multiband radio equipment capable of executing various waveforms, promoting interoperability among the Armed Forces, was entirely designed and manufactured by AEL Sistemas, in accordance with the Joint Operational Requirements of the three Forces.
The delivery of the units marks the consolidation of the 100% nationally produced RDS as a Strategic Defense Product (PED) and establishes a significant milestone in the technological development of the Brazilian Defense Industrial Base, with AEL Sistemas as the main partner in the development.
AEL is the Brazilian subsidiary of Israeli company Elbit systems. The radios underwent extensive and rigorous battery tests following all military standards requirements.
After the prototype delivery, the expectation is that the Ministry of Defense will acquire an initial batch for distribution among the forces and the development of doctrine for the vehicular version of the system. To achieve this, an interoperability waveform (Software embedded in the Radio) must be developed for the Navy, Army, and Air Force on the platform.
Advancing to the next stages of the RDS is crucial for Brazil to reduce external dependence in the field of communications. For strategic programs, it will represent a significant leap by providing several applications in the context of technical command and control interoperability.
As an example, the coordinated RDS can enable communication between Army ground troops, an F-39 Gripen fighter from the Brazilian Air Force (FAB), and the Multipurpose Ship of the Navy, all in the same data link.
According to Elbit , the maturity of the system allows for its fast implementation in some Defense fronts that better fits the project, especially in the Integrated Border Monitoring System, the Armored Forces program, and the operation of
Medium-range anti-aircraft artillery.
According to Elbit Software-defined radios (SDR) offer secure and reliable communications on the battlefield. Strong error correction algorithms eliminate the possibility of lost data packets, and a self-healing, self forming ad-hoc networking capability ensures robust data communications of several megabits per second at adaptable bandwidths.
SDRs allow for simultaneous transmissions of wideband waveform (WF) and narrowband WF. The narrowband WF includes simultaneous voice and data transmission using only 25Khz of the VHF bandwidth, while allowing a maximum data rate of 115.2Kbps. A distinctive automatic routing and relay capability dramatically extends its reach even over harsh field conditions, while mobile ad-hoc networking (MANET) provides continuous IP networking connectivity throughout any mission. The SDR is housed in a single radio unit, improving operational efficiency by enabling the use of fewer radios in the field.
