Abstract:	The real time kinematic system for precise carrier phase differential processing of the measurements from several dual band dual systems JPS receivers is con-sidered in the paper. The system is composed of four JPS Eurocard receivers ex-changing with measurements and results of processing. The system is based on the general purpose kinematic engine. It includes carrier phase differential ambiguity filter, on-the-fly ambiguity resolution, coordinates and velocity estimators. The system has two options: (i) free processing or moni-toring, (ii) attitude determination. First option supposes several kinematic RTK’s working simultaneously, while under second option the whole antennae array is sup-posed to move as a rigid body. The second option applies additional geometry constraints due to the constant be-tween antennae distances. The paper is organized the following way. The architec-ture is discussed at first. Then the methods are described. The performance results illustrating special features of the system are included into the text where description of the features comes. Mathematical details are placed in the Appendixes.
