One of possible approaches of working out of a small-sized integrated navigation & landing complex for an unmanned aerial vehicle is presented. The construction concept, design, and software of the complex are considered. An example of working out of a small-sized onboard navigation & landing complex based on the suggested approach and results of its flight tests are resulted.

Keywords: unmanned aerial vehicle, inertial navigation system, MEMS, global navigation system, magnetic compass, the system of air signals, the optimal processing of information, integrated navigation system.

Aleshin B. S., Antonov D. A., Veremeenko K. K., Zharkov M. V.

Results of the first stage of investigation of design possibilities and the main properties of the tightly-coupled inertial/satellite navigation system are given in the article carried out under the support of the Russian Foundation for Fundamental Research. The main objective of the first stage of investigation was development of theoretical bases for the creation of the integrated system. The main feature of the research is inclusion of the GNSS multiantenna receiver in structure of еру system that allows obtaining attitude determination

Keywords: integrated navigation system, inertial navigation system, multiantenna satellite navigation system, optimal information processing.
