Carlson BRX7 and Skyplots from Rinex Files
Hi Jeff, What tool are you using in Emlid Studio? I am not super familiar with Emlid Studio but I wanted to take a look at what you were seeing. When I upload my observation 23o file (what I have on hand) I can see that all of the GPS, GLONASS, GALILEO and BeiDou data is there. The funny thing is that the sky plot does not generate for any of my data. I am wondering if there might be an easier fix for you.
I also typically recommend using 2.0.3 for the Rinex convertor, I have had better with that one. I may not get back to you till after Thanksgiving (it's in October in Canada).
Hi Nolan. I was using Static Processing and Convert to RINEX to view the observation data. You can also use it to convert some other forms of raw data to Rinex. It's a pretty useful tool, but I was merely using it to be sure that all constellations were observed. I also use RTK Library, which is an open source program. Also, very useful.
So I get the same results that you do when converting with 2.0.5. All the GNSS constellation data is in the observation file, but none of the navigation data, hence no sky plot. But like I've said in my previous post I've been able to figure it out. By telling Rinex Hemisphere to create the Navigation Data file for Glonass, BeiDou, and Galileo, which by default is "optional" you'll get that information in your Observation file and you'll be able to view sky plots. The trick is that Rinex Hemisphere does NOT default to the correct file extension. If you don't know what they are, then it simply creates text files with nothing of value in it. So by adding the following extensions when saving the Navigation Data file you'll get all that juicy skyplot data right in your observation file.
GPS Nav = yyN (.24n)
GLONASS Nav = yyG (.24g)
Galileo Nav = yyL (.24L)
BeiDou Nav = yyF (.24F)
So when you click in the box next to a constellation, and select the save as location, be sure to add the appropriate extension. See attached screen shot.
I'll ask around and see if there are any better solutions out there.
What other Rinex convertor were you using that gave you the sky plot in the .o file? I was talking to some of the folks at Hemisphere and they say the .o files normally don't contain any navigation data.
I'm only using Hemisphere to convert the .BIN file from my BRX7 to a .24o. I haven't been able to find another way to do it. I find it very odd that they say that .0 files don't normally contain navigation data, because their converter puts GPS data in it by default. It just doesn't add the other constellations by default.
I agree with you, it is pretty odd why they decided to do it that way. I'll let you know if in my poking around, I find out why exactly they did it this way
