Геолокация

Translation:

Geolocation

When geolocation and wi-fi are turned on, it does not determine the location

Perhaps you are within the Russian Federation or eastern Europe?

I'd make an educated guess that you have a WiFi Only model iPad - and not a WiFi+Cellular model...

Only WiFi+Cellular models of iPad have GNSS/GPS capabilities - this being a function of the iPad Cellular chipset. WiFi Only models of iPad have no GPS capabilities with which iPad Location Services can derive location. This fundamental difference may significantly impact your ability to use mapping or other Apps that require accurate/precise location data - in particular if real-time positioning (e.g., a moving map) is required.

WiFi Only iPad models can only “infer” their location from a database lookup of neighbouring WiFi networks for which the geographic location is known, or the geographic location of your public IP address. For static applications in urban locations, where the location of IP public IP addresses and WiFi networks are known, an “inferred” location can be relatively accurate. However, in rural locations, or when using a Cellular/Satellite/VPN connection, location accuracy of an inferred location [if it works at all] may be very inaccurate.

Access to GNSS/GPS satellite navigation signals are routinely jammed by the Russian Authorities. Access to Apple's geolocation services, via the Internet, may be similarly blocked.
