Abstract:	The conventional indexes used to describe GNSS positioning performance, such as satellite visibility, dilution of precision (DOP), and signal-to-noise ratio are quite useful in the open sky but are not useful in a land road environment. This paper proposes a new index for describing GNSS positioning performance in a land road environment. This new index, which is called Sky-View based DOP (SVDOP), is derived with reference to the Sky-View Factor (SVF). The usefulness of the proposed index is analyzed by comparing the SVDOP and SVF in a land road environment after the singularity points are selected and the SVDOP is calculated.
