Abstract: Principle and application of GNSS (B) is a compulsory course for geographic information science major students. The experimental part is one of the core contents of this course, and it is also a professional skill that students of this major must master. This paper analyses some problems existing in the experimental teaching of GNSS Principle and Application (B). Referring to indoor positioning technology, an idea of reforming GNSS signal receiving equipment is put forward. The outdoor GNSS satellite signal is introduced into the indoor by using electromagnetic wave signal transponder to realize the purpose of GNSS experiment indoors. With the help of network teaching information platform, the method of establishing the laboratory test platform can be extended to more fields.

Key words: Indoor positioning, Indoor experimental platform, GNSS
