It's fun to see engineers get giddy. The new 5Hz GPS receiver from ETek had them turned on their heads.
The new EB-85A
from ETek is a 5Hz update GPS receiver. Super sensitive, extremely configurable, this is the GPS unit we've been dreaming of. The baud rate is adjustable from 4800 to 115200bps, the output rate is adjustable from 5 down to 1Hz, the accuracy is 2.6m with DGPS. It's pretty nifty.
