I didn't remember right. With a cell-enabled iPad, leave airplane mode off, then go to settings and shut off Cell Data, Wifi, and Bluetooth. Nothing's transmitting, but the cell chipset is still running so you can receive GPS signals.
Android lets control the GPS chipset separately from the phone and data segments of the radio. Ipads lets you work around it, but iPhones do not.
You have to put iPhones in Airplane mode.
