Rover Processing with Network RTK and Quality Indicators

correction to users. This is performed by measuring the regional errors at the reference station locations and interpolating them for the location of the rover. The quality of those corrections is dependent on the reference station spacing, the location of the rover, and the characteristics of the measurement errors. This paper introduces a network RTK quality indicator based on the characteristics of the measurement errors. The indicator assumes that the more linear the regional correlated errors, the better the interpolation methods will perform. The linearity of the network measurement errors is measured and weighted based on the distance to the rover. The quality indicator shown, successfully models the network RTK performance over time in the observation domain. There is an insignificant improvement in the position domain when fixed ambiguities are used however there is a small yet notable improvement in the percentage of fixed ambiguity solutions.
