FIELD: navigation system.
SUBSTANCE: invention relates to satellite navigation and can be used for real-time monitoring of navigation field integrity of global navigation satellite system (GNSS). Technical result is that together with consumer navigation equipment (CNE) place the storage equipment for consumer time scale and hardware of high-precision comparison of consumer time scale with GNSS system time scale, synchronise consumer time scale with GNSS system time scale, record time of receiving navigation message from spacecraft (SC) GNSS according to consumer time scale, determine pseudo range between each SC and consumer equipment, determine one set of consumer coordinates by three values of pseudo range. Obtained sets are analysed, several sets of consumer coordinates are obtained, SC GNSS is detected, navigation messages of which must not be used for navigation solutions.
EFFECT: broader functional capabilities.
