Hello Сергей,
Good day. Thank you for your question.
Here we must take note of the Satellites In Use (Configurator>Status > GNSS>Satellites in Use) as this determines the location positioning. The minimum satellites (In Use) should be 4 and the recommended does not have a fixed value but this should be 4 or more. The higher satellites In Use, the more accurate the positioning. Depending on your location, you can choose the correct combination of satellites (GPS+GLONASS+Galileo or GPS+GLONASS or GPS+Beidou) to know which setup is able to capture more satellites.
Please let me know if this helps.
Kind regards.
