The reference sensor and the associated GLONASS inter frequency biases will be defined in the
following way:
Reference Antenna Enter the antenna type attached to the reference station receiver the corrections are received
from so phase centre corrections can be applied accordingly
Receive RTK
If network corrections are received, select the type of RTK network corrections to be received so
corrections from ionospheric and tropospheric modelling will be used for position calculation accordingly.

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 according to the rover
position sent previously. Therefore, the generation of the i-MAX
format requires a position of the rover sent to the network.
The product sends observations of the Master corrected by the
network processing, and correction differences of all the
Auxiliaries to the rover. The rover must interpolate the network
corrections (master and auxiliary)to get the best solutions for its
location. This product is best suited to broadcast transmission.
The MAX format is based on RTCM v3.1 standard format.
The product sends interpolated corrections (ionospheric and
geometric) to the rover. These corrections are generated from
an automatic or fixed cell according to the rover position sent
previously. Therefore, the generation of the Virtual RS format
requires a position of the rover to be sent to the network. The
end user has no information about error/correction sizes.
FKP stands for "Flächen-Korrektur-Parameter" (Area correction
parameter).
FKP is a means of representing the distance-dependent errors
affecting an entire network region, in a non-standard but
published open message for all to understand. The product
