Необходимый для этого уровень надежности навигационных решений обеспечивает алгоритм расширенного автономного контроля целостности спутниковых данных – Advanced Receiver Autonomous Integrity Monitoring (ARAIM). В статье рассматривается АRAIM для двухчастотных безыоносферных комбинаций псевдодальностей BeiDou второго и третьего поколений (BDS-2 и BDS-3). Для расчета уровня безопасности по высоте (vertical protection level – VPL) в ARAIM использовалось гипотетическое сообщение для поддержки контроля целостности (integrity support message – ISM). Выполнена оценка влияния различных параметров ISM на доступность ARAIM в зависимости от места расположения потребителя. Результаты показывают, что географическая доступность ARAIM для BDS-2+BDS-3 несколько выше по сравнению с одной BDS-3 главным образом благодаря большему числу видимых спутников. Доступность системы BeiDou в Северной и Южной Америке зависит от точности измерения дальности от спутника до потребителя (user range accuracy – URA). При сокращении URA с 2,0 до 0,5 м доступность ARAIM для BDS-2+BDS-3 в Северной и Южной Америке увеличивается с 50 до 99,9%.</p></abstract><trans-abstract xml:lang="en"><p>With the addition of multi-frequency and multi-constellation systems, the Advanced Receiver Autonomous Integrity Monitoring (ARAIM) algorithm is expected to provide a global vertical and horizontal guidance for the localizer performance of vertical guidance (LPV)-200 approach phase in aeronautical navigation worldwide. Currently, the second and third generations of the BeiDou navigation satellite system (BDS-2 and BDS-3) provide their services to users. We consider ARAIM for dual-frequency iono-free BDS pseudorange combinations. With the aim to improve the service performance of the BDS-2 and BDS-3 systems, the assumed integrity support message (ISM) was used to calculate the vertical protection level (VPL) for the LPV-200 approach. The impact of the different parameters of ISM on the ARAIM availability was evaluated. The results demonstrate that, compared with BDS-3, the global coverage of availability for BDS-2+BDS-3 is slightly higher, mainly due to the increase of the number of visible satellites. The availability of BeiDou in the Americas is affected by user range accuracy (URA). With URA decreasing from 2.0 to 0.5 m, the ARAIM availability of BDS-2+BDS-3 in the Americas increased from 50 to 99.9%.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ARAIM</kwd><kwd>VPL</kwd><kwd>BDS-2</kwd><kwd>BDS-3</kwd><kwd>LPV-200</kwd><kwd>доступность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ARAIM</kwd><kwd>VPL</kwd><kwd>BDS-2</kwd><kwd>BDS-3</kwd><kwd>LPV-200</kwd><kwd>availability</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при частичной поддержке программы Китайского национального фонда естественных наук (National Natural Science Foundation of China) (гранты №№ 41974032, 41674034), программы «Свет Запада» (Light of the West) Китайской академии наук (гранты №№ E017YR1R04, E123YR1R03, XAB2019B21), Китайского национального плана ключевых исследований и разработок (грант № 2016YFB0501804), а также программ «Таланты высокого уровня» (High Level Talents) (грант № Y923YC1701) и «Передовые научно-исследовательские проекты» (The Frontier Science Research Project) (грант № QYZDB-SSW-DQC028) Китайской академии наук.
