radio signals will not interfere with the transmission of
the correction data.
The RT-3020 when configured as a reference sta ion
can transmit corrections to any number of roving
receivers capable of picking up the radio signal and
decoding one of the three GPS correction formats
[ RTCM , CMR, or NavCom proprietary] transmitted. At
2.4Ghz, data being broadcast via modulated radio
carrier frequency is limited to line of sight for error free
reception. However, the signal can be received in less
than ideal environments, though some data loss could
occur. The
SSR integrated into the RT-3020 has a line of
sight range up to a maximum of 10km.

When setting up the reference sensor, it is best to have
the
reference station sensor elevated above the roving
sensors since radio signals of such high frequency tend
to travel a shorter distance than their lower frequency
counterparts, and are apt not to penetrate obstructions
as well over distance. This also affords the reference
sensor to transmit to all
rove s in all directions with
minimal obstruction. Figure 8 & 9 illustrates a proper
and improper
RTK reference station installation.
