Abstract
The continuous construction of global navigation satellite system and its extensive application have expanded the service areas of IGS GNSS continuous observation stations, thus improving the requirements of their data quality, so it is necessary to understand its data quality in a wide area of the world. Considering system global coverage and development maturity, this paper aims at GPS, makes a statistical analysis about multipath impacts, data observation integrity and o/slps, and obtains preliminary conclusions on IGS GPS data quality.
