Abstract

The invention relates to a Beidou/GPS dual-mode navigation positioning device and method, and the method comprises the steps: receiving a Beidou/GPS satellite signal, and reading satellite data; analyzing and calculating the satellite data, obtaining a first Beidou/GPS difference correction number, and storing the first Beidou/GPS difference correction number at a reference station; receiving a Beidou/GPS satellite signal and reading the satellite data; carrying out the analyzing and calculation of the satellite data, and obtaining a second Beidou/GPS difference correction number; carrying out the matching and correction of the first and second Beidou/GPS difference correction numbers, obtaining a corrected Beidou/GPS difference correction number, carrying out the position analysis, and carrying out the dual-mode positioning; and enabling an airborne moving station to carry out the continuous positioning. Compared with the prior art, the method can improve the positioning speed and precision. The method also can achieve the continuous positioning under the condition of no satellite signal, and improves the positioning precision.

Description

technical field [0001] The invention relates to the field of airborne navigation, in particular to a Beidou / GPS dual-mode navigation and positioning device and method. Background technique [0002] With the widespread application of drones, it has brought more convenience to our lives and is playing an increasingly important role. It has attracted the attention of various countries and attracted many research institutions and scientific research units to invest in it. The autonomous take-off, navigation, and landing of drones, as well as related application fields such as drone plant protection, power line inspection, and disaster monitoring, rely heavily on high-precision navigation and positioning technology. [0003] In places such as high mountains, dense forests, and high-rise buildings in cities, GNSS signals are easily blocked. The Beidou / GPS single system may have too few observation satellites under severe signal blocking conditions, resulting in large positioning e...
