Automated complex for testing and recording
The automated complex for testing and recording (AKKR-1M) is jointly developed by ZAO NRTB and OOO Aviatest. The complex is a part of the Automated flight control system, it is installed on the Yak-40 flying test bed. The aircraft is made available by the Siberian Aeronautical Research Institute named after S. A. Chaplygin.
AKKR-1M is used to record electromagnetic environment during flight tests with a view to assess electromagnetic compatibility of the cellular networks radio electronic facilities of GSM-900 standard and radio electronic facilities of the takeoff and landing navigation. The complex also ensures measurement of the electromagnetic environment in the following frequency ranges:
- 0.190-1.75 MHz – radio homing beacons
- 74.3-75.3 MHz − radio marker beacon
- 108-118 MHz – on-course beacon (ILS, VOR)
- 118-137 MHz – VHF radio stations
- 329-341 MHz – glide-path beacon
- 726-1048 MHz – short-range radiotechnical navigation system/mobile radio beacon group and GSM-900 systems
- character and parameters of ECM signals in the navigation system frequency band;
- whereabouts of the flying test-bed that determined the effect of interference on the operation of the system;
- whereabouts of the interference source.
Recording of the electromagnetic environment is done automatically which permits accumulation of information to analyze situation on the test site.
During monitoring of the electromagnetic environment there is also a possibility to get the following information:
AKKR-1M is a unique development that allows doing all the measurements in the shortest possible time. A use of the AKKR-1M will help significantly reduce material and time resources required for flight testing.
