Proper setup of a reference station minimizes GNSS
errors in the rover. The reference GNSS receiver is
set up at a known surveyed location. With this
position locked in, it transmits its code, clock, and
reference station coordinates information to the
roving receiver(s). The roving receiver(s) use this
information to correct each GNSS measurement
received.
If the receiver will be used or transported above
40,000 ft (12.2 km), it must be located in a
pressurized compartment.
The SF-3040, when configured as a reference
station, can transmit corrections to any number of
roving receivers capable of picking up the radio signal
and decoding one of these correction formats:
NavCom proprietary, RTCM 2.3/3.1 for Network RTK,
CMR, or CMR+. The signal can be received in less
than ideal environments, though some data loss may
occur.
Setup of the reference station receiver above the
roving receivers is recommended to enable
transmission to all rovers in all directions with minimal
obstruction. High- frequency radio signals generally
travel a shorter distance than lower-frequency signals
and do not penetrate obstructions as well over
distance.
Refer to Chapter 8, RTK Setup, in the StarUtil 3000
User Guide for detailed instructions.
