Navigate Crowded Spectrum with Confidence

Accelerate regulatory compliance and ensure mission success with RFIAT, the agency-trusted Radio Frequency Interference Assessment Tool.

Trusted by INDUSTRY and Some of the world’s leading space organizations

A 30+ years Legacy
Evolved for Today

Our aerospace engineers bring over a decade of hands-on experience in space TT&C and telecommunications. This expertise is rooted in the history of RFIAT, originally developed in the early 1990s. For decades, RFIAT has been ESA’s go-to tool for nearly all coordination activities and critical WRC-related studies, proving its reliability across thousands of scenarios.

Since 2015, Arpsoft has maintained and advanced this legacy, launching the modern RFIATnet platform in 2019 after co-development with ESA. Crucially, our team continues to provide active RFI assessment consultancy directly to ESA, ensuring our expertise remains current and mission-focused. Today, RFIATnet is trusted not only by ESA but also by other leading space agencies (like DLR), EUMETSAT, and innovative private companies globally. Choosing RFIAT means leveraging decades of operational validation and expert insight for today’s spectrum challenges.

Navigating Today’s Spectrum Challenges

Secure your spectrum access and guarantee mission performance with our proven tools and expert guidance

The Growing Spectrum Challenge

Thousands of new satellites and NGSO constellations are creating unprecedented RF congestion, sharing limited spectrum and dramatically increasing the risk of harmful interference.

The Cost of Uncertainty

Unmitigated interference leads to mission-critical data loss, costly operational delays, and significant regulatory hurdles that can jeopardize your entire project.

The RFIAT Solution & Expertise

RFIAT provides a robust, agency-validated simulation engine to model scenarios and identify interference. Combined with our expert consultancy, we deliver the analysis and insights you need to file with confidence.

Powerful Analysis at Your Fingertips

An intuitive yet powerful interface designed for comprehensive interference assessment.

01. Comprehensive Modeling

Effortlessly configure complex scenarios (Satellites, ES, GSO, EESS) through a clear GUI. Model with precision using comprehensive libraries of ITU-R antenna patterns (App. 7/8, S.1428, etc.), diverse modulation schemes, or your own custom inputs.

02. In-Depth Link Analysis

Dive deep into the RF details. Analyze real-time spectrum overlap, Doppler shift, and filtering effects. Assess detailed interference metrics (Io, C/I, No/Io) and crucial link parameters like detailed budgets (VTVR, ITVR).

03. Dynamic Geospatial Visualisation

Understand the dynamic context of your mission. Visualize orbits, ground stations, and sensor footprints in real-time on interactive 2D/3D maps with elevation contours and link status.

04. Statistical Reporting & Compliance

Generate comprehensive statistical reports (CDFs, histograms, time series). Leverage the Multi-Run Manager for batch processing and the Import Statistics Dashboard to overlay and compare results. Automatically generate key compliance metrics for trusted regulatory filings and coordination activities.

Automate & Scale with the RFIAT Python API

Integrate RFIAT’s validated simulation engine directly into your workflows.
