GP20-U7 with Arduino and HC-12

Hello everyone, I really need some help with my senior design project at my University.
I am creating a GPS locator for individuals trapped in natural disasters. I have taken two Arduino UNOs, attaching each with one HC-12 signal transceiver, and added a GP20-U7 SparkFun GPS. I have gotten to the point where both Arduinos can communicate, however; I am not receiving all data from the GPS.
This is what is sent from the Arduino connected to the GPS sends to the receiving Arduino:
$GPRMC,,V,,,,,,,,,,N53
$GPVTG,,,,,,,,,N
30
$GPGGA,,,,,,0,00,99.99,,,,,,48
$GPGSA,A,1,,,,,,,,,,,,,99.99,99.99,99.99
30
$GPGLL,,,,,,V,N*64

My question now is, what possible problems constitute to this lack of data?

Thank you very much, all help is wanted and appreciated.

Show your code.

Most like cause is you not sending all the data, or you not parsing it correctly on the receiving end.

The GPS is indoors most likley as its clearly not getting a fix, so no data to send, take it outside where it needs to be to work reliably.

Or the GPS or its antenna are faulty.
