Is there a step by step process to convert sets of raw satellite data to traditional GPS lat/long points or a website that takes the data and processes it?
Example of the raw satellite data:
$GPS30,180445.0811520511,2701.0000,N,09349.0000,W,20162.9,KM
Have looked thru the following:

It looks like a NMEA message.
gpsworld.com has some details about how the NMEA messages are structured:
It goes on. But based on that info, I would say the time =
18:04:45.0811520511 UTC
; latitude =27° 1' N
; longitude =93° 49' W
; and altitude =20162.9 km
.That site also has an Excel workbook for converting the coordinates from
DDDMM.MMMMM
into other formats.I'm not aware of any sites or software that process those NMEA strings (though there might be some). That said, armed with an understanding of the message components, there should be lots of ways to go about processing the data yourself.
One option would be to use Excel to separate the string into columns and then create formulas for the coordinate conversion based on that workbook.
