GPS not working on iPad

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.

When using Satellite internet systems, such as Starlink, the public IP Address of the internet gateway through which your internet traffic is routed may be in a completely different country/region to your actual location. Where your iPad is using this location to infer its location, you will observe an incorrect derived location.

If yours is not a WiFi+Cellular model, your available options are:

• Substitute your WiFi Only iPad for a WiFi+Cellular model; this does not commit you to provisioning Cellular service for your iPad, but does provide the GNSS/GPS functionality required for accurate determination of your location.
• Add an external GPS receiver to your WiFi Only iPad. These are often used in marine, aviation and vehicular applications - and can be either directly connected via Lightning or via Bluetooth. There are various third-party manufacturers, of which two are BadElf and Garmin GLO.

If you do have a WiFi+Cellular model iPad, your location might be relevant. GNSS/GPS jamming has become a regular issue in some parts of the world - such as Russia, Eastern Mediterranean, Baltics and the Middle East. If you are located in one of these regions, you might reasonably anticipate seeing issues.

GNSS/GPS signals are generally line-of-sight, requiring a clear view of the sky to be reliable. To exclude the possibility of unintentional screening of the signal, remove any fitted case from the iPad - and go outside.

If you still have problems, try resettings your iPad's network settings - as this reset has been known to resolve location derivation in some cases:

Settings > General > Transfer or Reset iPad > Reset > Reset Network Settings

Finally, if the issue remains unresolved, a visit to the the Genius Bar at your local Apple Store or Apple Authorised Service Provider (AASP) - where the technicians will be able to test and assess your iPad:

if your ipad is wifi only rather than cellular then it don't have build in gps
