В настоящее время внедрение глобальных навигационных спутниковых систем ҒНСС на горнодобывающих предприятиях Казахстана достигает больших объемов. Несмотря на их повсеместное использование, до сих пор не изучена проблема искажения спутникового сигнала - "теневой эффект". Описан опыт исследования ошибки за счет "теневого эффекта". Установлено, что при приближении к откосу точность измерения в режиме "кинематика" падает, а критическое отстояние, удовлетворяющее точности измерения, составляет не более 5 м. Ключевые слова: глобальная навигационная спутниковая система, теневой эффект, базовая станция, открытые разработки, производительность труда, погрешность. Қазіргі таңда ғаламдық навигациялық жер серігі жүйелерін ҒНСЖ Қазақ- станда тау-кен ендірісінде енгізу ауқымды келемдерді алады. Олардың бар- лық жерде қолдануына қарамастан, жер серігініц дабылдардың "келең- келік эффект" қателігін зерттеу әлі күнге дейін толықзерттелмегвн. Бүл жүмыс- та "келеңкелік эффект" қателігін зерттеу тәжірибесі сипатталған. Түйінді сездер: ғаламдық навигациялық жер серігі жүйесі, келеңкелік эсер, базалық бекет, ашық еңдеулер, еңбек енімділігі, қателік. Currently, the introduction of the global navigation satellite systems (GNSS) in mining enterprises of Kazakhstan reaches high volumes. Despite the widespread usage they has not investigated the problem of distortion of the satellite signal "shadow effect". This paper describes the experience of the study due to the "shadow effect"error The results showed that accuracy of "kinematics" mode decreases due to approach to the slope, and the critical distance which provides satisfying accuracy is not more than five meters. Key words: global navigating satellite system, shadow effect, base station, open-cast minings, labor productivity, error. (Полный текст: Архив, 2012г., №3-4, С. 49)
