Connectors pinout



Reach can both receive power from USB, acting as a device and source power to the port acting as a host. To use Reach in OTG mode you will need to connect 5V power source to

RTK capable GNSS for Precise UAV Mapping and Navigation. Use as a standalone GPS for sub-meter accuracy or add the Reach RS+ RTK for centimeter accuracy.

GPS, GLONASS, BeiDou, Galileo, QZSS and SBAS

Two receivers or NTRIP are required for centimeter accuracy

For better understanding of RTK, PPK and NTRIP check an article on how these technologies work. Also, see a detailed article on how PPK works in UAV mapping.
