Onboard small-sized transmitting system “ISK” is designed for aircrafts and provides operation with automatic dependent surveillance system ADS-B 1090ES generating extended squitter messages. ISK system is onboard transmitter unit.
ISK provides generation and transmission of squitters (DF=18) containing the following information:
- air velocity;
- aircraft identification index and flying status;
- air-emergency status/priority;
- aircraft operating status;
ISK performance features
- ISK system can operate together with ATC transponder or in a standalone mode.
- Based on control and navigation information ISK system generates extended squitter messages.
- ISK system doesn’t require in-flight operational control. System has a radiation termination mode (“READY” mode) activated by signals from on-board controller or control panel commutator.
- ISK system is constantly under automatic performance monitoring with operational information output.
Specific design features
ISK is designed as a monoblock unit which doesn’t require amortization or separate ventilation.
Onboard small-sized transmitting system ISK passed all tests, including exploratory tests.
ISK meets the following documents: ICAO (vol. IV) requirements 10 App., Doc 9871 (vers. 1), RTCA DO-260А as related to ADS-B OUT В1 class.
