iSXblue/SXBlue II GNSS Series Technical Reference Manual
35
o
A GPS receiver, with a freshly downloaded GPS almanac, will track better under
obstructed conditions like in forestry applications
o
It can take up to 5 minutes for a GPS receiver to download a complete Ionospheric Grid
from an SBAS satellite. A special feature of the SXBlue II Series is its ability to
extrapolate the downloaded grid (see chapter 2)
o
With the GNSS models, if using a source of differential correction that does contain
GLONASS correctors, the
G-Dif
feature of the receiver will internally generate
correctors for and use all GLONASS satellites in view. This unique feature requires 3 to
5 minutes of tracking constant GPS differential corrections signal.
o
For forestry applications, if SBAS visibility is marginal, it is preferable to activate the
receiver outside of forest canopy condition, let the receiver track the SBAS signal for at
least 5 minutes, then the data collection can start
o
It takes about 2 minutes of GPS tracking for carrier phase smoothing to be effective
o
If doing submeter work, it is preferable to let the receiver settle (for about 15 to 30
seconds) after a loss of position fix, prior to resume data collection.
1.4.6 Available Software and Utilities
This section gives a brief overview of the various software and utilities available for the iSXBlue/SXBlue
II receiver family. Throughout this manual, various menus of some of the utilities are presented to help
configure and monitor the receivers for specific applications.
All software and utilities are free (with the exception of the SXBlue Server and the Geneq EZSurv post-
processing software) and can be downloaded from the
www.sxbluegps.com
web site. The SXBlue Server
features a trial mode with full functionality but with a limitation of one hour per execution. Please contact
your SXBlue representative for more information on how to purchase these products.
1.4.6.1 SXBlue Config
SXBlue Config is a
free utility
to configure and monitor the SXBlue receivers. It also allows
logging NMEA messages and raw data. Available for Windows 2000/XP/7 (32-bit and 64-
bit) and for Windows Mobile 6.x.
1.4.6.2 SXBlue RTN
When your field software does not feature a built-in NTrip and/or DIP client, SXBlue RTN
is a
free utility
that allows the SXBlue receivers to use RTK/DGPS Internet corrections
from a network. It uses only one communication port with the SXBlue GPS to both send the
corrections and receive the NMEA messages. A virtual COM port is created on your
computer to allow your software to receive RTK corrected positions. Available for Windows 2000/XP/7
(32-bit and 64-bit) and for Windows Mobile 6.x.
1.4.6.4 SXBlue Server
SXBlue Server is a TCP Direct IP server with NTrip emulation to set your base station on
the Internet. Besides being used as a stand-alone server, it is capable of linking to an NTrip
Caster as a mountpoint. It also features a mirror mode to allow a base station to be carried in
the field. Available for Windows XP/7, 32-bit and 64-bit.
