Abstract
Network RTK (Real-Time Kinematic) is a technology that is based on GPS (Global Positioning System) or more gener-ally on GNSS (Global Navigation Satellite System) measurements to achieve centimeter-level accuracy positioning in real-time. Reference station placement is an important problem in the design and deployment of network RTK systems as it directly affects the quality of the positioning service and the cost of the network RTK systems. This paper identifies a new reference station placement for network RTK, namely QoS-aware regional network RTK reference station placement problem, and proposes an algorithm for the new reference station placement problem. The algorithm can always produce a reference station placement solution that completely covers the region of network RTK.

If we can prove that the polygon is completely covered by the reference station placement solution produced by Algorithm 2, we have proved that the given area A is completely covered by the solution

Summary
Network RTK (Real-Time Kinematic) is a technology that is based on GPS (Global Positioning System) or more generally on GNSS (Global Navigation Satellite System) measurements to achieve centimeter-level accuracy positioning in real-time. That reference station placement problem is described as: Given a set of potential locations where reference stations can be set up and the locations of the users, select reference station locations among the potential reference station locations such that the total number of reference stations is minimum subject to a constraint, that is, the maximal distance between any user to the closest reference station does not exceed a parameter Dmax This maximum distance constraint must be satisfied in order to guarantee the accuracy of the positioning services. We identified and proposed an algorithm for an area-oriented reference station placement problem for network RTK [6]. In this paper we propose a new reference station placement problem, namely, QoS-aware regional network RTK reference station problem, and extend the area-oriented reference station placement problem to guarantee to generate a reference station placement solution that covers the whole service area.
