Software-Defined Radios & Advanced Waveforms

Modirum Gespi has a consolidated track record in developing and delivering SDR systems and advanced waveforms:

• Developed and delivered the new generation of SDRs for the Brazilian Army.
• Co-develops, alongside experts from the Army Corps of Engineers, a set of waveforms (HF and X bands) for initiatives such as BLOS and satellite-based applications.
• Internally develops concepts for Electronic Warfare, aiming at technological gains toward more sophisticated and sovereign solutions.

• SDR architecture based on a platform with fast reconfiguration through software updates.
• Multiband RF front-ends covering HF to X-band (mission-configurable).
• Support for advanced waveforms: anti-jam, FHSS/CHIRP, cognitive/adaptive, BLOS, and SATCOM.
• Secure and hardened software stack with role-based access control and OTA (over-the-air) updates.
• Integrated SIGINT/EW capability: wideband monitoring, real-time spectrum analysis, and waveform capture.
• Modular I/O: Ethernet, serial, digital I/O, RF connectors (SMA/N), synchronization/GPS interfaces.
• Development toolchain for creating, simulating, validating, and deploying waveforms (host tools + automated test bench).

• Secure tactical voice and data links (anti-jamming / MANET).
• Beyond-Line-of-Sight communications and satellite integration.
• Electronic Warfare: SIGINT collection, signal classification, electronic attack and protection.
• Unmanned/autonomous systems: guidance, swarm control, and secure telemetry.
• R&D and waveform prototyping for defense laboratories and engineering corps.
• Interoperability exercises and joint operations (adaptation to standards and waveforms).

• Operational Agility: Rapid reconfiguration of capabilities without hardware replacement.
• Resilience: Dynamic waveform adaptation ensures higher resistance to interference and jamming.
• Technological Sovereignty: Co-engineering within national programs strengthens domestic capabilities.
• Cost Efficiency: Software-based updates and modular hardware reduce lifecycle costs.
• Easy Integration: Modular interfaces and standard toolchains enable platform integration (vehicles, UAVs, ground stations).
• R&D Acceleration: Internal toolchains shorten the path from concept to validated capability.
