avionics navigation system

avionics navigation system is a high-reliability airborne navigation solution professionally introduced and integrated by Tianjin Shengkai Linghang International Trade Co., Ltd. (Tianjin Shengkai Linghang International Trade Co., Ltd.), which is widely used in general aviation, modern aircraft such as unmanned aerial vehicles platforms, light fixed-wing aircraft and helicopters. The system integrates global navigation satellite system (GNSS), inertial measurement unit (IMU), air data computer (ADC) and flight management function (FMS), supports GPS, GLONASS, Galileo and Beidou (BDS) four systems multi-frequency point reception, and ensures continuous accurate positioning and track tracking in complex electromagnetic environment and remote airspace.

system adopts an embedded architecture that meets DO-178C Level A and DO-254 safety standards. It has dual redundancy design and automatic fault detection and isolation (FDIA) capabilities to meet the airworthiness requirements of EASA CS-23/CS-27 and the CCAR-23 Department of the Civil Aviation Administration of China. Its core host integrates high-precision AHRS (Attitude and Heading Reference System) to provide real-time pitch, roll, yaw angle and acceleration data with a response delay of less than 20ms. The supporting multi-function display unit (MFD) supports map overlay, waypoint planning, terrain awareness warning (TAWS-B), ground proximity warning (GPWS) and ADS-B IN/OUT collaborative monitoring functions, significantly improving flight situation awareness and operation safety.

Tianjin Shengkai Linghang, as China's leading avionics supply chain service provider, has established in-depth cooperation with many internationally renowned avionics manufacturers (such as Garmin, uAvionix, FreeFlight Systems and domestic avionics enterprises, CLP 20, Aerospace Star, etc.), which can provide customized system integration, FAA/EASA/CAAC airworthiness certification support, ground test equipment (GSE) matching, full life cycle technical training and localized maintenance services. All delivery systems are ISO 9001:2015 and AS9100D quality management system certification, complete technical documentation, DO-160G environmental test reports and EMC electromagnetic compatibility test certificates.

This system has been successfully deployed in many domestic navigation companies, flight training schools and industrial-grade vertical take-off and landing unmanned aerial vehicle (VTOL) platforms to help customers realize digital air traffic control docking, low-altitude intelligent operation and RNP-APCH precision approach capability construction. It is the key infrastructure for building a modern, intelligent and compliant aviation operation system.
