A new range of high-precision GNSS antennas is designed for superior accuracy and reliability, with both active external antennas and passive internal ceramic antennas. The antennas provide precision, high bandwidth, and an advanced signal design for GPS, GLONASS, BeiDou, Galileo, IRNSS and SBAS navigation. They are designed for demanding GPS applications that require centimeter-level accuracy by combining precise point positioning (PPP) of L1 and L2 or by combining L1 and L5 bands with real-time kinematic (RTK) satellite navigation. Applications include aviation safety, UAVs, transportation, autonomous vehicles, agriculture and land and hydrographic surveys.

The ADNET autonomous delivery network is a technical solution to transport medical samples and quarantine materials in cities. It uses an RA3 drone, unmanned vehicle RG1 and RH1 hub station to deliver medical supplies without relying on manpower, alleviating time spent in traffic and the cost of traditional delivery. Supplies retrieved by the RG1 vehicle are delivered to the RH1 hub for sorting and redirecting, while the drone transfers the supplies between hubs. The RG1 then delivers goods on the receiving end. The system was demonstrated during China’s COVID-19 epidemic prevention and control period, reducing contact between samples and personnel.

The VECTOR-400 is a compact autopilot designed specifically for unmanned aerial vehicles. It features a robust enclosure and a military-grade connector for harsh environments (MIL-STD 810 and MIL-STD 461). Features enable sea-skimming (extremely low-level flight) and the capability to navigate without GNSS. The VECTOR-400 is able to continue a mission in case of individual sensor failure and when subject to jamming, maintaining accurate estimations of attitude and position. Advanced algorithms provide stall prevention and the ability to carry out an efficient gliding maneuver in case of engine failure. Its air data attitude and heading reference system and inertial navigation system provide high-precision attitude information and reliable navigation under demanding circumstances.
