The processes of error development in an inertial navigation system are analysed. With this aim, the standard structures of error development were extracted in the inertial system. Error development was defined in the standard structures. Error development in the inertial navigation system is concluded according to the results obtained in the work.

advanced technologies for remote learning and science are very actual, especially in the case of epidemic or pandemic. Videoconference is an area of information technology that provides simultaneous two-way transmission, processing, conversion and presentation of interactive information at a distance in real time using hardware and software of computer technology.Using a web conference allows you to expand the capabilities of the communication form in which several computer users connected to the Internet constantly see the same screen in their web browsers. Some web conferencing systems include features such as text messaging, video recording, voice over Internet protocol (VoIP), and full video. However, despite all the advantages of this technology, there are also disadvantages to using the product.

A lot of methods exist for the diagnostics of synchronous generators and diesel engine installations. One of these methods is the diagnostics with the help of currents and voltages spectrum analysis. The spectral composition of the output currents and voltages is influenced by technical condition of the synchronous generator -wear of bearing units, shortcircuit of some turns of windings, etc. Such approach to the monitoring of the electro-mechanical "diesel-generator" system gives an opportunity to discover faults in the primary motordiesel, non-uniformity of the operating process in its cylinders, and in the synchronous generator itself. This method of technical diagnostics does not require a deep interference into the diesel system and generator scheme, and can be applied without breaking of the operation of the installation. Mathematical modelling of the diesel-generator system was realised with the help of special software. The software realises the mathematical modelling of diesel engine, generator and provides the dynamic balance of the system. A ship diesel-generator has been taken for the experimental investigations.
