Navilock 8004u

Rainer Plattner shared this problem 3 months ago
In Progress

Hi folks,

wanna connect a USB GPS NL8004u via sensormanager

it shows:

u-blox GNSS receiver

u-blox AG

-vendor: 5446

-product: 424

but there is no connection button!


I'm using Android 10 on Hanspree Tablett, the gps connector app shows acurate position data, but locus does seem to recognize the gps mouse.


any help would be appreciated

Hello Rainer,

thanks for the additional info. I can't guarantee, but most probably your device will work in the next app versions (probably middle of September). After the update, give it a try, and please let me know if there will be any problems. Thanks.

After Update locusmap in October Navilock 8004u is correct identified and locusmap is connecting => great!


After some testing there are two major problems

  • locusmap loses connection after 1min and does repeating this behavior for quit some time until it is stable for about 5-10min, then the circle starts again (tablet at the same position)
    - as there is no autoconnection available you have to push the Connect button 10to15 times
  • the 8004u supports these frequenzes
    • Frequenz:
    GPS: L1, 1575,4200 MHz
    GLONASS: L1, 1602 (k x 0,5625) MHz
    BEIDOU COMPASS: B1, 1561,0980 MHz
    GALILEO E1, 1575,4200 MHz
    QZSS L1, 1575,4200 MHz
    but shows only GPS & GLONASS in locusmap => we would prefer GPS & Galileo

any idea????

Hi,

thanks for the tests. Does your device disconnect even when the screen is still turned on the whole time?

About missing data: may you please enable in the app GPS settings, recording of the NMEA messages? Then try to use your device for a while. After that, the Locus/data/NMEA directory should be a newly recorded file with data, which may help me to check this issue. Thanks.

Hi,

sorry for the delay, but i found time to generate the data file - i hope it has enough information, i have a bigger one but it's over 2mb, so i couldn't load it up


And for your question: Yes it disconnects while using locusmap and to clarify not disconnecting the USB connection just losing the signal from the GPS mouse

thx for your support

Hello Rainer,

thanks for the NMEA file. If you look inside, satellites are reported thanks to "GSV" messages. Two letters before this define source. As you may see, only "GPGSV" (Navstar) and "GLGSV" (Glonass) are inside. There is no "GAGSV" message (Galileo), so the result visible in the app is correct. If your device supports more sources, they seems not to be reported over NMEA messages.
