Conversion of GPS heights into normal heights has become a hotspot in survey engineering, the Quasi-geoid surface can be very complicated especially in a large survey area or in complicated terrain, just adopting several GPS/leveling points to construct quadric surface model to fit the Quasi-geoid surface has some limitations, precision could not be guaranteed. So, such demand us that we should partition...
Artificial neural networks (ANN) has been used in GPS heights conversion. It is impossible to avoid gross errors in conversion of GPS heights. So, the paper puts forward a kind algorithm to detect gross error considering of ANN used in conversion of GPS heights. After the three tests, the algorithm proposed for disposing of gross error is validated in conversion of GPS heights, and some practicable...
