The article describes the development of methods for improving the noise immunity of user’s equipment through the integration of global navigation satellite systems receivers and inertial sensors. The disadvantages of satellite navigation systems include the low reliability of angular measurements, quite a long time carrier-phase ambiguity resolution, insufficient baseline length of the interferometer which directly affect the measurement uncertainty of spatial orientation. The method of integration of sensor data with goniometric equipment of satellite navigation systems, which allows to increase the efficiency of using goniometric equipment consumer due to the fact that these systems define the parameters of the spatial position of the object. In addition, this method allows you to narrow bandwidth tracking systems satellite navigation systems to a minimum, ensuring the accuracy and noise im-munity of the close to potential. In integrated inertial-satellite navigation systems, the aggregation allow to eliminate instrumental errors, such as drift of the gyro sensors, reduces to a minimum the time of initial exhibition. The use of closely related integrated inertial-satellite navigation systems with integration on output parameters is the most appro-priate as this system parameters close to optimal and do not require substantial processing of the hardware resources. In turn, closely related system requires further development of hardware and software, like inertial navigation systems and satellite navigation systems at all levels. If such completion is impossible, for example, using imported equipment, the aggregation provides only secondary treatment or at the level of the output data. In the first case it is a loosely cou-pled system, and the second case is an open system.
Keywords: aggregation, phase shift, navigation equipment.
