Influence of Gravity Disturbance Resolution on GPS/Gravity Boundary Value Problem

    Graphical Abstract
    • Abstract
  • Based on the theory of GPS/gravity boundary value problem,the errors caused by gravity disturbances of different resolution are simulated and analyzed using numerical simulation methods.The result shows that the relationship between data resolution and result precision is osculating,and 2 km resolution data can satisfy the demand of the centimeter level geoid in hilly area.Meanwhile some feasible suggestions are put forward.
