It's been a long time since I used this but here is a code for reading from COM port. There should be a decoding part in your GPS manual

Pavel

Private Sub Form_Load ()
  ' Buffer to hold input string
  Dim Instring As String
  ' Use COM1.
  MSComm1.CommPort = 1
  ' 9600 baud, no parity, 8 data, and 1 stop bit.
  MSComm1.Settings = "9600,N,8,1"
  ' Tell the control to read entire buffer when Input
  ' is used.
  MSComm1.InputLen = 0
  ' Open the port.
  MSComm1.PortOpen = True
  ' Send the attention command to the modem.
  MSComm1.Output = "ATV1Q0" & Chr$(13) ' Ensure that
   ' the modem responds with "OK".
  ' Wait for data to come back to the serial port.
  Do
     DoEvents
  Buffer$ = Buffer$ & MSComm1.Input
  Loop Until InStr(Buffer$, "OK" & vbCRLF)
  ' Read the "OK" response data in the serial port.
  ' Close the serial port.
  MSComm1.PortOpen = False
End Sub
