The paper introduces the brief results of modeling an antenna array designed to be used as part of anti-jamming satellite navigation equipment. The study describes the procedure for calculating the weight coefficients of the antenna array based on the orthogonalization of signal and jamming spaces. According to the weight coefficients found, the resultant antenna patterns are plotted. Findings of the research show the results of how the depth of sample accumulation influences the effectiveness of adaptation to the jamming environment

High Degree

Acoustic transponders are employed in underwater navigation in situations in which a high degree of accuracy is required. Typical applications include underwater search, mapping, photography by a submersible or a towed vehicle and positioning of underwater work systems. The network of transponders, of which there may be only two or three, or which may be very extensive, is implanted by a support ship or by a submersible. The network can be located geographically by a satellite navigation equipment to an accuracy of 0·25 nm. This accuracy (or even accuracy within ± 1 mile) is sufficient to locate the network after a period of disuse. Acoustic navigation of a vehicle is accomplished relative to the network, to accuracies of the order of several feet.

Moon Exploration

The article contains the overview of perspective satellite navigation systems for other planets and objects of Solar System. The example of this conception for the Moon is considered. The paper contains the brief overview of Moon exploration perspectives. An overview of countries’ space agencies programs on the Moon with automatic and human missions. The problem of lunar and cislunar navigation is considered, the ways of its solution are overviewed. One of the possible cases for lunar and cislunar navigation system realization is to create the satellite system similar to the Earth’s GNSS using the existing experiences. The main goal of the article is the conception of lunar receiver designed for the lunar navigation satellite system in case it is similar to GLONASS. The formulas’ simplifications because of Moon’s features are considered, including: absence of atmosphere and as a result absence of ionospheric and tropospheric delays; more simple gravity field because of small flattering (almost spherical shape). The conclusions on perspectives of the lunar navigation are made.
