The INNOVV system does NOT use the Global Positioning System (GPS) for position tracking as it purports to use. It is designed and configured to use the Chinese BeiDou Satellite Navigation System (BDS). As yet BDS does not support the GPS frequencies however it appears to be moving in this direction. Technically the K2 system works OK and does not have any issues EXCEPT for when the BDS overhead satellite coverage is not adequate enough to function. Periodic outages here in New Zealand are frequent and after a frustrating period of discovery the core issue is one of system configuration: BDS versus GPS. INNOVV are misrepresenting the facts when they state 'GPS' when it is in fact BDS. According to the BeiDou official report http://en.beidou.gov.cn/SYSTEMS/Officialdocument/
June 2020 is a target date to add multi-spectral frequency which should alleviate the issue and utilise other satellite tracking systems on demand. The attached screenshots (PDF document) from a recent ride using DashCam viewer show the issue: 1) No speed 2) mid-ride the BDS satellites come back, and 3) The entire ride showing the outage blocks when the BDS satellites were unavailable. Alongside this my Garmin GPS did not miss a track beat.
Look forward to this system working as it was represented in the sales pitch. Disappointing in its current configuration.
AS the "GPS" does not function with TS recordings, has anyone just not bothered attaching the "GPS" unit? The main feature I want is in case of an accident and if the MP4 file can get corrupted if there is a power failure then the accident will not be recorded.
Same issue for me: more or less random display of speed. Sometimes no speed is indicated for hours on end (despite the unit being restarted after stops), then suddenly it reappears during a clip. Very disappointed, since my Garmin never loses track during the same time period.
Check with the manufacturers: ask them the question " does the INNOVV product use BDS or GPS?" And ask them to post the answer.
Because the system firmware only supports the BDS frequencies.I rifled the whole firmware to see If I can find something interesting, what I did. But I did not find any GPS/BDS related settings or frequencies.
Could you point me to where the GPS/BDS functions are located within the firmware?
INNOVV is a PRC developed & manufactured product that utilises the BDS network. It does not have access to the GPS system.Just because a product is made in China does not mean it has no access to GPS. The Flight Controllers of some of my drones are also Made in China and, according to the chips in the GPS antenna, they use GPS. Anyone can use GPS, as the frequencies are open to anyone.
If you follow my original post you will find the documents that discuss BDS accessing the GPS frequencies, however this has yet to happen.Sorry..I have not found these documents. Maybe you can point me to the correct files?
I think the reason why the K2 GPS sometimes looses connection while my Navigation system does not, is the difference in quality of the GPS receivers.
I was not able to open the case of the GPS module without breaking it, so I could not check the used chipset. But maybe Rock/Innovv can provide us a picture of the chip
@innovv
Can you post a close-up picture if the chip of the gps module?
Edit:
I was able to open the case without completely breaking it.
The readings on the board says:
1818_dg628
gmouse V1.2
The chip itself is covered by a shield, which I still have to remove.

If you follow my original post you will find the documents that discuss BDS accessing the GPS frequencies, however this has yet to happen. I found this out purely through the frustration of having blocks of 'GPS' data missing from my rides down under here in NZ. I tracked the BDS satellite constellation times against my logs and it showed the lack of coverage. My Garmin (using GPS) was happily recording the track whereas the BDS had dropped out. Please refer to my initial post and the PDF file attached.
How do you know it uses BDS instead of GPS?
Update as at 18 August 2020. The same issues re 'GPS' data still exist. I note lots of comments around the "GPS' systems etc not working. I would suggest that the base technology is (mostly) OK, rather its the use of the Chinese BDS and the incomplete coverage is the fundamental issue. As yet, the BDS has not integrated the multi-spectral frequency protocols that were to allow access to the US GPS system. Until INNOVV has the ability to 'multi-system' access such data then dropouts will continue to be an issue.
