SPSLux offers a wider range of correction types to support all rovers and geodetic applications. Please find below a description of the supported correction types, along with available message type(s).
Correction Type |
Message Type |
Correction Description |
DGNSS |
RTCM 2.3 (Type 9, 2) |
Standard Code only correction for DGNSS applications needing only decimeter lever accuracy. |
iMAX |
RTCM 3.1, RTCM 3.2 MSM5
|
Individualized Master Auxiliary Correction, uses a real reference station as the source for the network corrections. |
VRS |
RTCM 3.1, RTCM 3.2 MSM5 CMR
|
Virtual Reference Station, represents the network to the rover as single simulated reference station with a short baseline length. |
NEAREST |
RTCM 3.1, RTCM 3.2 MSM5
|
Nearest Station, single baseline correction for nearest reference station, does not apply network corrections or mitigate distance dependent errors. |
StationName_RAW
|
RTCM 3.2 MSM5
|
Raw observations data stream form a single site (StationName). |
StationName_RAW_ORD
|
LB2
|
Original raw observations data stream form a single site (StationName) |
The above-mentioned correction types are streamed within a wide range of different mountpoints. A list containing the available mountpoints can be downloaded below in form of a concise table, summarising information regarding mountpoint names, correction types, message types, satellite systems and connection settings.
If any further correction types or formats are required, feel free to contact our customer service center.
Note:
Only iMAX, VRS and DGNSS correction types provide network corrections. NEAREST and StationName_Raw do not apply network corrections and should thus be used for RTK or post-process applications.
If a network RTK correction is required, choosing between iMAX and VRS correction type depends on the technical specifications of your receiver. Modern rovers will support both types, appropriate rover settings assumed. Consider that both correction types provide equal positional accuracy and comparable convergence time. For your GNSS receiver settings, please contact your equipment supplier.
