2.2 LD7 CONNECTIONS
2.2.1 Coaxial Connections
The LD7 rear back plate is fitted with 2 coaxial antenna connectors.
2.2.1.1 Dual Antenna / Coaxial connections
The combined GNSS and L-Band antenna is connected to the MAIN ANT GNSS Antenna
connection.
Where the LD7 is used to derive a heading output, a second GNSS antenna is connected
to the Auxiliary Antenna (AUX ANT) connection of the LD7.
This two antenna option will require the user to install 2 antennas and 2 cable runs.
More details of this configuration are in the Appendix.
A schematic example is shown below:
This option uses two antennas to derive high accuracy position with output of heading
information.

Manual Title:
LD7 Operations Manual
Ref.:
AB-V-MA-00555
Rev No:
A9
Page 14
The combined LBand / GNSS antenna is connected to the MAIN ANT TNC connector.
A second GNSS antenna is connected to the AUX ANT TNC connector.
Note that the greater the baseline between the antennas, the better the heading accuracy
will be. For example:
1m baseline = 0.3° accuracy with RTK fixed quality
3m baseline = 0.1° accuracy with RTK fixed quality
10m baseline = 0.03° accuracy with RTK fixed quality
2.2.1.2 Three Coaxial connections
There is an optional configuration to use a separate L-Band antenna to receive the Veripos
Corrections. This can be used when masking may cause a problem or when working at
high latitudes where the satellites are low on the horizon.
To utilize a 3 three antenna combination a conversion kit can be fitted to the LD7 unit. This
can be installed by a Veripos technician.
A schematic example is shown below:
Survey Requirement
After equipment installation it is recommended that a calibration survey is carried out to
compute any heading C-O and establish any offsets for the Main GNSS antenna position.
These values can then be entered in to the navigation or DP software if required.
Further guidance regarding antenna installation can be found within the LD7 Installation
Manual.
