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.
