Geo++ RINEX Logger

Geo++ GmbH

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!

Ratings and reviews

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)

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.

Looking forward to testing. Would be good to have a bit more technical info on the monitor display. Another comment suggests its not possible to log static, I'm not sure i agree with this, and i think it should produce most accurate results on L1. On Samsung enable developer options..... Force full GNSS measurements Track all GNSS constellations and frequencies with no duty cycling.

What's new

- Improved doppler computation
- Introduced measurements view
