In the configuration where a base is only broadcasting to a single NorthStar, the Base would need
to be equipped with a Yagi antenna pointed at the NorthStar. NorthStar Radio A would be
equipped with a Yagi Antenna pointed at the Base, while NorthStar Radio B would be equipped
with an Omni Antenna to broadcast to multiple Rovers.
An example of a single NorthStar network (only one Rover shown).
It is possible to add multiple NorthStars in sequence for a long baseline connection to an RTK
Rover. To add an additional NorthStar to the network mentioned above, radio A would be
configured to channel 5. Radio B could be configured to channel 2 (There are many options here
if the channel is free). Rovers attached to this NorthStar would be configured to channel 2. For
the best performance, it is ideal to have Rovers connected to the Base as directly as possible.
Each NorthStar added in series adds roughly ½ second of delay in the corrections. Additionally,
baseline length can also degrade the RTK results resulting in an addi/- 1mm error per
kilometer of baseline. To reach multiple NorthStars, the Base requires an Omni Antenna.
An example of a chained NorthStar network.
Multiple-Base-Multiple-Rover setups are the best way to collect the most accurate results
possible.
Bases cannot be configured on the same network; separate channels are required.
Multiple Bases reduce baselines and transmission delays. Bases or NorthStar Radio Bs cannot
transmit on the same channel, when they are within communication distance of one another.
This means up to seven kilometers (4.3 miles) line of sight. Rovers should be configured to
receive from the Base closest to them, within line of sight. The maximum number of units linked
to one Base or NorthStar is 28.
The best practice when setting up a large RTK network is to draw a radio network map. Examples
of such a map can be found in the
. The map in Appendix E is also a good example of
possible configurations.
