neo 8 za razliku od neo 6 bi trebalo da ima glonass tj da vata sve satelite i ruske i kineske koliko sam ja uspeo da shvatim....

Ublox M6n je 20 dollara a M8N je 55. Razlika u ceni ne opravdava koliko dobijes u performansama osim ako bas imas novca pa pravis neki high end sistem i kupujes samo najbolje. Ja imam M7N a drugar M6N i nikakve razlike ne primecujemo. Uglavnom minimum 8 satelita i 2.0 Hdop a ide do 13 satelita 1.4 Hdop

M8N vredi svaki dinar, prima sva cetri sistema GPS, QZSS, GLONASS i BeiDou, a uz to je dosta brzi u fiksiranju pozicije.

Kako vam je podešen m8n (Hz i baud rate) i može li se podešavati naknadno? Da li je fabrički podešen i da li ga može pixhawk prihvatiti kao dual gps zajedno sa m6 ili lea6 gps-ovima? Ako je neko probao...
