Drone based calibration for MAFI navigational system

1. MAFI infrastructure comprises of Nav-Aids (ILS, TACAN, DME (LP/HP) & DVOR) which require periodic air calibration to ensure the accuracy of the parameters. To undertake the periodic calibration task, UNIFIS- 3000 (Flight Inspection system) has been installed on Do-228 aircraft. The task of calibration of MAFI assets has increased manifold with commissioning of large number of MAFI bases. The issue of non-availability of calibration facility at high altitude regions as well as to explore the alternate means of calibration to reduce the workload of FIS, drone based air calibration system is being perused.
