Hi all,
while looking for solutions for receiving multiple GNSS services, I stumpled across the new ublox M8 chipset and found several discussions about new GNSS receivers equiped with that chip, always stating these to be much better in accuracy and precision than older receivers.
Especially I'm talking about the NEO-M8N: http://www.csgshop.com/product.php?id_product=180 and MAX-M8Q: http://www.csgshop.com/product.php?id_product=171
Has anybody tested both modules under the same testing conditions? I'd like to know, which one would be more suitable for the usage in an copter. Clearly the M8Q is more compact, lighter and cheaper, but what about the overall "performance"? Someone stated the M8Q under the link above to be equipped with an active antenna. What does that mean and what is the difference to the patch antenna on the NEO-M8N?
A brief look in the datasheet unveiled the MAX-M8Q to offer higher data transmission rates of 10 Hz in concurrent mode, while the NEO-M8N just offers 5 Hz. Is that crucial for performance? The NEO otherwise comes with an SAW-filter.
So all in all I'm a bit uncertain, which module would perform better in combination with my pixhawk.
Thanks a lot and best regards
Lukas
