Abstract

The article presents a description of mathematical and simulation models of the functioning of the on-board navigation system of a spacecraft for the case when the device performs the task of monitoring space objects in conditions of a discrete or absent navigation field. This type of navigation field is manifested when spacecraft are located at altitudes above 2000 km above the Earth’s surface (for the GLONASS system). In order to achieve the required decision-making speed and measurement accuracy, it is proposed to expand the composition of the complex and apply deferred processing in the calculation process. The proposed complex includes: a free-form inertial navigation system, consumer equipment for satellite navigation systems and a software-configurable radio receiver. The simulation of obtaining heterogeneous measurements was carried out, as well as their joint processing by the navigation system, provided that the integration scheme is strongly coupled. It is assumed that under the specified environmental conditions, the software receiver can obtain measurements of current navigation parameters (range and radial velocity in the developed model) due to incoherent accumulation. Based on the results of processing, the current location of the consumer is estimated, which determines the accuracy at a given time interval of the complex in question
