2. The Auto-Dif application is pre-installed in the Application 2 memory of the SXBlue II
GPS and SXBlue II-B GPS but is not activated and requires a subscription. The Auto-Dif
application offers the following features:
Autonomous differential correction mode (with "calibration")
•
Standard Base Station mode for standard RTCM differential correction output
•
3. The L-BAND application is pre-installed in the Application 2 memory of the SXBlue II-L
GPS. The L-Band application offers the following features:
Uses OmniSTAR L-Band signal as the default differential correction source
•
Uses SBAS as a default input differential correction source when using
•
Application 1
Output or relay of differential corrections received from SBAS or OmniSTAR
•
signals in RTCM format (reference-free or moving base station)
Standard RTCM differential correction input from external source
•
4. Local-Dif (Rover-20cm) is a local differential Application in a Base Station / Rover
application. This option offers a floating solution for sub-20 centimeter accuracy and
requires the Local-Base be installed on another receiver operating as base station. This
Application uses proprietary RTCM and is only compatible with another SXBlue family
receiver as base station.
5. Local-RTK (Rover-5cm) is a local differential Application in a Base Station / Rover
application. This option offers a fixed RTK solution with OTF (On-The-Fly) capability for
sub-5 centimeter accuracy and requires the Local-Base application on another receiver
operating as base station. This Application uses proprietary RTCM and is only
compatible with another SXBlue family receiver as base station.
6. Local-Base (Base Station) is an Application installed on a base station for use with
Local-Dif and Local-RTK. As above, the RTCM output is a proprietary format and can
only be used with another SXBlue family receiver as mobile.
The Local Differential Applications can be purchased at any time from Geneq inc. or through an
authorized reseller. The necessary firmware with installation software and installation guide
along with the subscription code will be provided.
Two Output Rate options can also be activated and do not require any installation: 10Hz and
20Hz.
For carrier phase post-processing and Local Differential applications, an L1 Survey grade
antenna should be used instead of the L1 Precision Antenna supplied. Contact Geneq or an
authorized reseller for more information.
