I don't think there is for iPhones due to the privacy settings recently pushed to them. Which allows a user to block people from tracking them. It's mentioned in the Meraki help
"Forcing GPS Location
Due to Apple end-user privacy restrictions, it is not possible for EMM vendors to force GPS location on iOS devices without user notification, nor is it possible to permanently lock location services to be enabled.
The one exception to this is using 'Lost Mode', which can be found in the MDM commands on the Client Details page. Lost Mode forces location services on, while disabling all other functionality on the device. This can be used as a tool to remediate non-compliant users who are blocking location service requests from Systems Manager."
