Theoretically in the simultaneous observation of the high-precision GPS network solution mode, the selection of the independent baseline vector can be arbitrary with the same adjustment. But in the real situation, the results varies in different selections for the model of baseline solution is imperfect[1].

For the blind and partially sighted the visual cues which are a significant part of monitoring the environmental flow are either severely limited or non-existent. Thus the challenge is to be able to use man-made sensors and technology such as the smart phone based sensors to assist such individuals in monitoring the environment and collecting cues/ data about the environmental flow.
