Description
Use
AS05
L1 SmartTrack antenna with
built-in ground plane.
With GS05/GS06 or GS10/GS25.
AS10
GPS, GLONASS, Galileo, BeiDou
SmartTrack antenna with built-
in ground plane.
With GS10/GS25.
AR10
GPS, GLONASS, Galileo, BeiDou
antenna with large ground
plane and built-in radome.
With GS10/GS25 where higher
precision is required.
For example static surveys of long
baselines, tectonic plate moni-
toring and base stations.
AR20
GPS, GLONASS, Galileo, BeiDou,
QZSS reference station and
monitoring antenna with gold
choke ring ground plane.
Optional protective radome.
High end applications, including all
reference station and monitoring.
Especially suited for Network RTK,
where excellent multipath rejection
and the best phase centre stability
is required.
AR25
Dorne & Margolin GPS,
GLONASS, Galileo, BeiDou
antenna element with 3D
choke ring ground plane.
Optional protective radome.
With GS10/GS25 where higher
precision is required.
For example static surveys of long
baselines, tectonic plate moni-
toring and base stations.
