PORTABLE GROUND-BASED DIFFERENTIAL CORRECTION SYSTEM Russian patent published in 2019 - IPC B64C13/18 

FIELD: measurement; testing.

SUBSTANCE: invention relates to the field of navigation instrumentation and can be used in aircraft navigation systems. For this purpose, the formation of navigation information (220) for aircraft (202) based on reception (1400) of satellite signals (212) in group of reference receivers (308) in group of locations (326) is provided. Determine (1404) level of accuracy (352) for group of reference receivers (308) based on satellite data (320) generated from satellite signals (212). Show (1406), when specified group of locations (326) of group of reference receivers (308) does not meet required level of accuracy (350). Generate (1408) messages (322) using navigation information (220) from satellite data (320), when group of reference receivers (308) has required level of accuracy (350). Source (304) of navigation information is arranged to receive satellite data (320) from group of reference receivers (308) and determine level of accuracy (352) for group of reference receivers (308) based on satellite data (320). Specified group of locations (326) is first group of locations (326), accuracy level (352) for group of reference receivers (308) based on satellite data (320) is first level of accuracy (330) for first group of locations (326) for group of reference receivers (308), and satellite data (320) is first satellite data (332), and source (304) of the navigation information is configured to determine second level of accuracy (336) for group of reference receivers (308) based on second satellite data (320) generated by satellite signals (212) from group of reference receivers (308), after moving part (334) of group of reference receivers (308) to second group of locations (326), which differs from first group locations (326). Source (304) of the navigation information also contains control self-observation device (405), made with possibility of control self-observation (354) for determining group of locations (326), where group of reference receivers (308) was placed, and to show whether level of accuracy (330; 336) for group of reference receivers (308) has required level of accuracy (350) in specified group of locations (326), and configured to generate messages (322) using navigation information (220) from satellite data (320) when group of reference receivers (308) has required level of accuracy (350).

EFFECT: technical result is expansion of functional capabilities.
