Would you happen to know of a Garmin or Bad Elf GPS receiver that can provide sub-meter accuracy?
I am familiar with the:
Trimble R1 ( < 1 meter accuracy )
Bad Elf Surveyor ( ~ 1-meter stationary accuracy with SBAS+PPP )
Geneq ISXBlue II ( 60 cm; 95% real-time with SBAS corrections )
this is where I am getting the info for these recievers from:
