Geo++ RINEX Logger

Geo++

About this app

Geo++ RINEX Logger uses the most recent Android API services to log your device's raw GNSS measurement data into a RINEX file including pseudoranges, accumulated delta ranges, doppler frequencies and noise values. So far, it supports GPS/GLONASS/GALILEO/BDS/QZSS for L1/L5/E1B/E1C/E5A (as supported by the device) and has been successfully tested on many devices.

So far, we were able to achieve fixes for L1/L5 in a zero baseline setup.

For more information on supported devices, please refer to the official Android site for raw GNSS measurements:

https://developer.android.com/guide/topics/sensors/gnss.html

The Geo++ RINEX Logger generates file names according to the current hour and date of year and will append data if the file already exists. If you wish to log separate files within the same hour, please move or rename the most recent file first before you start the next session. The files are stored in the "Geopp_RINEX_Logger" directory inside the root directory of your internal storage.

We highly appreciate all kinds of feedback like suggestions for improvements or bug reports. Enjoy!

Hi, so after the updated version was released yesterday, it says that the files are mow stored in the internal storage, I used Samsung s8 to collect the data. But now whenever I am trying to open the file from my internal storage, it says the app to open the data file is not in my phone and to search for it in Play store. May I please know which app I need to download for my files to open from the internal storage.

This msg it's to everyone. This app is great BUT, pls note that's not helpful for the static mode if you are using the internal receiver of your mobiles! It's necessary to connect your mobiles to an external L1/ L2 receiver and record the data for at least 15 min. Pls note that until yet there is no any mobile in the world that has an L1/ L2 gnss internal receiver.

Hi. It looks your app works fine, however I am not sure what the files in your GEO++ folder are. I have four of them: GEOP320U.19o, GEOP320V.19o, GEOP320W.19o and GEOP320T.19o. It suppose to be one single RINEX multifrequency file uploadable to OPUS Gov. site (here in the U.S.), for postprocessing. However, if I upload any of them, it constantly sends me the following message: "The RINEX dataset submitted to OPUS only contained data for a single frequency. Dual frequency data is needed for processing. Aborting..." Also, it forces me to process it as 'Rapid Static', instead of 'Static', despite having collecting data for 4 hours. Is there a cure for this? Thanks. (I have Samsung S 10)
