The development of the interference assessment package RFIAT (Radio Frequency Assessment Tool) started around 1990 and focused as the first primary application on sharing models with the Mobile Service (MS), in order to determine potential sharing conditions in the 2 GHz bands. Soon thereafter, a number of modules were added which allowed general interference assessment between many different service applications, such as the low and high density Fixed Service (FS) systems, High Altitude Platform Stations (HAPS), Radars on ground, on planes and on satellites, Passive Sensors, Intersatellite Links, Fixed Satellite Service (FSS), Mobile Satellite Service (MSS) and many more.
RFIAT has been used for basically every ESA coordination with spacecraft of other space agencies, administrations and/or private satellite operators. It has also been used in most ESA studies to assess interference situations related to World Radio Conference agenda items since 1992. More than a thousand different scenarios have been assessed and the tool has obtained a very wide recognition at international level.
In 2015 Arpsoft replaced the tool creator, Dr. M. Otter, in providing the maintenance to ESA. In 2018, with a co-funding with ESA, Arpsoft developed a new and enhanced version of RFIAT.
In 2019 RFIAT is placed on the market by Arpsoft.
By means of time-based simulation the tool allows a comprehensive interference assessment.
Different interference metrics and statics are computed providing deep interference analysis.
Different systems can be simulated as Fixed Service (FS) systems, High Altitude Platform Stations (HAPS), Radars on ground, on planes and on satellites, Passive Sensors, Intersatellite Links, Fixed Satellite Service (FSS), Mobile Satellite Service (MSS) and many more.
Different reccomended ITU patterns can be simulated as well as user design antenna patterns.
The tool provides dashboards for a user-friendly usage.
Charts, tables, maps, files are available for the user analysis.
