2.1 ALIGN Setup (For both models)
ALIGN functionality requires one receiver to operate as a Master receiver to send information to a Rover
receiver.
Any OEMV or OEM6 receiver model with a minimum of L1 & GLONASS tracking capability can act as
a Master receiver. Receiver features may be limited if basic Position Velocity Time (PVT) only models
are used (i.e., N1G). See Appendix A for more information.
A typical ALIGN setup includes:
•
Two NovAtel OEMV receivers
1
or
•
Two NovAtel OEM6 receivers
1
or
•
A combination of OEMV and OEM6

•
Two GPS+GLONASS capable antennas
•
Data communication link between both receivers

. Communication examples include a radio,
modem or serial cable.
