AirNav Ensures Readiness to Handle Navigation Disruptions

Tangerang (ANTARA) - AirNav Indonesia, the Perum Lembaga Penyelenggara Pelayanan Navigasi Penerbangan Indonesia, ensures its preparedness to handle and anticipate disruptions to GPS or navigation signals on aircraft. The President Director of AirNav Indonesia, Capt. Avirianto Suratno, in an official statement received in Tangerang on Thursday, said that the phenomenon has long been known in international aviation under the name GNSS RFI (Radio Frequency Interference). He continued that the agency has taken precautions through the implementation of comprehensive standard procedures. ‘GNSS RFI handling is one of the global safety agendas envisaged by ICAO (International Civil Aviation Organization). In this regard, AirNav Indonesia has prepared through the implementation of comprehensive standard procedures,’ he said. The accuracy and integrity of the signals are enhanced through augmentation systems consisting of Aircraft-Based Augmentation System/ABAS, Ground-Based Augmentation System/GBAS, and Satellite-Based Augmentation System/SBAS. The satellite signals reaching the Earth’s surface operate at low power, therefore the system is designed to be layered using augmentation technology to maintain accuracy and integrity in various field conditions. ‘Radio frequency interference from various sources on that signal is technically referred to as GNSS RFI,’ he said.
