Operational

Before commencing a flyover test, frequencies are carefully chosen to suit local conditions in consultation with operators and the NRA as appropriate. The aircraft measurement system is accurately calibrated against a ground based reference emission. Airborne field strength measurements are linked to positional information derived from the Global Positioning System (GPS) satellite navigational system. An analysis (and display) approach is then provided which meets clients’ requirements.

Detailed planning is also undertaken with the national civil aviation administration and in-depth discussions will be held with all operator(s) involved in the survey, to obtain an understanding of any network or operational issues. Last but not least, TestTech will ensure that all necessary regulatory requirements are in place before commencing a survey.

The result will be similar to the picture below (dependant on client’s requirements), which clearly identifies certain areas of high field strength, marked red and yellow. In addition the raw data will also be provided, which will allow further analysis by clients using their own mapping programs
