of the antenna is the “front” of the antenna when orientating. The antenna comes equipped with
mounting hardware.
Bases can be equipped with Yagi or Omni antennas depending if they are broadcasting to a single
endpoint, or multiple end points. If multiple end points for the corrections from the base are
needed, an Omni antenna must be used. If installing a Yagi, point the Yagi to the desired endpoint
for the corrections. If installing an Omni, mount in a vertical orientation, on a mast or other high
point. The antenna comes equipped with mounting hardware.
Installing the Cell Antenna
If your unit comes equipped with a cellular modem, install the cellular whip antenna in a vertical
orientation. While a cell antenna does not have the additional stringent requirements of the
other antennas, a cell antenna should not be contained in a metal box.
Installing the Iridium Antenna
If your unit comes equipped with an Iridium modem, the Iridium antenna needs to be installed.
This antenna should be installed with as clear a view of the entire sky as possible.
Similar to GNSS satellites, Iridium satellites travel closer to the horizon than over top of your
location. There are a limited number of satellites in the sky, so to maintain the best possible
connection, the larger the continuous volume of the sky the antenna can see the better.
The Iridium antenna can cause interference with the GNSS receiver so should be placed a
minimum of 1 meter away from the GNSS antenna; 10 meters of distance is ideal.
Installing RF Cables
Connecting the RF cables to the antennas involves transitioning the cables through a weather
protective enclosure for the Resolute and the power system. This can be done, depending on the
environment, through a downspout on the enclosure, or through polyphasers in the wall of the
enclosure (not supplied).
If using polyphasers, the polyphaser in line with the GNSS antenna must allow +15V DC Pass-
through, as the GNSS antenna is active. RF cables supplied by Alert Geomatics are marked with a
part number and color code. The color code matches the ring around the connector on the panel
to allow for easy tracing of cables. For an assembly diagram of the various RF cable configurations
see
Appendix D .
Setting the Base Position (Base Stations Only)
Setting the Base position tells the unit that the Base is configured in its final location. This MUST
be done for all RTK Base units and should be done after installing the GNSS antenna at the base
site and powering the unit. To automatically find the Base press the test button for 10 seconds
until the GNSS LED starts to flash blue. Release the button and the unit will reset along with
wiping the previously stored base position. The GNSS modem will start up and calculate a new
Base position that will be stored to survive power resets. Automatically setting the Base position
