Global Navigation Satellite System (GNSS) is playing an important role for the unmanned aerial vehicle (UAV), and the theoretical research, technical framework and application of GNSS-based navigation have been well developed. However, there is also a serious problem is that GNSS can not work when the UAV encircled in a round of special environment (e.g. indoor physical environment, urban street canyon and poor weather conditions) because of the challenge of GNSS signal unavailability. In order to compensate for this issue, a new efficient navigation algorithm based on the chip scale atomic clock (CSAC) is mentioned in this paper.
