Its because you are not getting GPS signal. Take device outdoors and use active GPS antenna with Bias for quicker reception.

Hi, Make sure your GSP antenna is match with your board, otherwise unable to get signal and you get black lat & long.

If the antenna is active type, the power should be given by main board, because there is no power supply on GPS antenna pad. If the antenna is passive, it is suggested that the external LNA should be used.

Regards,
