Abstract: In this paper, we further investigate the constructions of fuzzy connectives on a complete lattice. We firstly illustrate the concepts of left (right) semi-uninorms and implications satisfying the order property by means of some examples. Then we give out the formulas for calculating the upper and lower approximation implications, which satisfy the order property, of a binary operation.

Abstract: Navigation and positioning technology has stepped into the era of all schools of thoughts contend for attention. The progress, application, contribution and challenges of geomagnetic navigation technology are reviewed and analyzed. This paper introduces the principle and steps of geomagnetic navigation system, then compared with a variety of navigation technology to get the advantages and disadvantages of geomagnetic navigation; Summary of major contribution of geomagnetic navigation technology in the field of navigation and positioning; Finally briefly examine the important applications and the major challenges of geomagnetic navigation technology.
