[quote=hobo][quote=Twave03] Why are moving objects not supported ? [/quote] Accuracy of the fine timestamps which are used for LoRa TDoA positioning is disappointing, and multipath propagation brings even more troubles. So you need a (huge) number of messages to feed the filter/solver with their ts and other metadata to get not-too-disasterous positioning accuracy. Actually, that's why Actility had gave up and bought Abeeway which provides assisted GPS solutions.[/quote] Thanks for your reply! Some more questions arised... -Is this filter already implemented ? -Is each calculated loacation indpendendly calculated from the timestamps? Or does it take into account previous locations? -Are there algorithms implemented which assume the node is non moving ? -What would be the best way to have location updates for moving objects ? Send 'frequently' on SF11 ? Thanks!

"Tests are only available in a limited number of locations and only valid for stationary cases. Moving objects are not supported yet." Can someone explain if this is still the case ? Why are moving objects not supported ? Any details ? Thanks!
