important when using a reference station receiver from a different manufacturer as it allows the
correct application of GLONASS inter frequency biases.
The reference sensor and the associated GLONASS inter frequency biases will be defined in the
following way:
Enter the antenna type attached to the reference station receiver the corrections are received

i-MAX
RTCM standard for correction transmission including
message types 1002 & 1011 or message types 1004 &
1012.
Higher efficiency that RTCM versions 2.x. Supports real
time services with significantly reduce bandwidth.
With the Site Monitor option installed, all above message types are
available.
This means that DGPS positions (based on differential code) and
fixed positions (phase fixed position) can be achieved.
Otherwise only RTCM2.x (Type 1,2) and RTCM2.x (Type 9,2) are
available allowing DGPS position calculation.
1. User defined (as set in web interface)
2. RTCM Message 1230 (if contained in the incoming real-time data stream)
3. RTCM Message 1033 (if contained in the incoming real-time data stream)
4. Automatic (compute biases based on the data contained in the incoming real-time
data stream).
In most cases it is sufficient to use the setting "Automatic", as most
correction streams contain the reference antenna type.
If that is not the case the correct reference antenna type must be
selected.
Note that a vertical offset (height difference between marker and
ARP) of a user selected reference antenna will not be applied, e.g.
0.36m offset for a tripod setup
This means that if a tripod setup is used on the reference receiver,
this antenna setup must be configured on the reference receiver. On
the rover the reference antenna type should then be set to
"Automatic".
Description
No RTK Network is selected.
This term applies to a network real time product supplied
from the reference station that is closest to the rover
coordinate transmitted.
The product sends interpolated phase corrections
(ionospheric and geometric) to the rover. These phase
corrections are generated from an automatic or fixed cell
