telemetrymulti-channel

Validating drone performance in congested and contested electromagnetic environments
Evaluate radio links and mission-critical communications between Ground Control Stations (GCS) and unmanned aerial systems (UAS). This includes control, telemetry, imagery and live video streams essential to flight operations and mission integrity. Test scenarios should reproduce ISM and other operational bands, frequency hopping, spread-spectrum and multi-band operation to reflect field conditions.

Using Software-Defined Radio (SDR)
Software-Defined Radios (SDRs) enable flexible, repeatable RF testing by implementing waveform generation, modulation, demodulation and signal analysis in software. SDRs support emulation of interference, jamming and adaptive threat behavior to assess link resilience and to develop mitigation strategies for counter-drone and certification workflows.

Key features of the Proteus SDR

• Direct Digital Architecture: wide-bandwidth RF DACs and ADCs enabling signal generation to 10 GHz.
• Instantaneous transmit bandwidth up to 4.5 GHz and deep waveform memory for continuous or long-duration emissions.
• Instantaneous receiver bandwidth up to 2.7 GHz with high-fidelity capture for post-analysis.
• Programmable FPGA for real-time adaptation, Doppler and time-delay insertion.
• Configurable form factors: benchtop, desktop instrument or PXI/PXIe module with phase-coherent multi-channel operation.

Congestion, interference and susceptibility
Recreate congested spectrum conditions to verify susceptibility of control and telemetry links to interference or unintentional emissions. Proteus supports generation and analysis of wideband electromagnetic emissions and IQ-modulated signals for protocol-level testing.

Jamming and deception
Support for wideband noise generation covering multi-GHz bandwidths and coherent multi-output operation per module enables directional jamming and beamforming scenarios to evaluate vulnerability to deliberate RF attacks.

Validating real-life scenarios in the laboratory
Proteus functions as an RF recorder and digitizer, allowing capture of environmental signals and protocols to large memory for post-event analysis, root-cause investigation and repeatable test campaigns for certification or R&D.

Emulating a dynamic environment with movement
Real-time Doppler and time-delay emulation implemented in FPGA enable simulation of motion-induced frequency shifts and propagation delay. This provides repeatable validation for counter-drone systems and link performance under moving-target RF conditions.
