Receiver (a read-only field): Displays the product name
(“SP20”).
Correction Information: Source of corrections currently
used. If you touch this line, you may change the type
of connection through which corrections enter the
SP20 (SBAS, NTRIP, DIP, RTX IP or RTX L-BAND; see
page 12 for all the details). By touching the “+”
symbol after selecting “NTRIP” or “DIP”, you may add
a new NTRIP or DIP provider respectively.
Use monopole: By activating this function, you allow the
SP20 to deliver 3D positioning, the height of the SP20
above the ground being accurately known in that case.
External antenna model (only if an external GNSS
antenna is connected to the SP20 via plug [10] (see
page 3): Choose the model of external GNSS antenna
used from the available list (possible antenna models
are 111660, 111661, SPGA Rover, Zephyr 3 Rover).
Logically, when this option is visible in Settings, then
Use monopole (above) is not.
Configuration File
: Allows you to run a file containing a
set of commands intended to modify the configuration
of the high-accuracy GNSS module. The file should be
a text file with the “txt” extension and should have been
saved to the Download folder. To have the receiver
executing the desired set of commands, just touch the
txt file containing this set of commands. The response
of the high-accuracy GNSS module to the set of
commands will be returned in a file named
“<file_name>.txt.log”, also visible in the Download
folder.
RF Band selection: Touch this parameter to choose
which GNSS frequencies to receive (L1, L2, L-Band).
L1 and L2 are enabled by default and L-Band is
disabled by default. L1 cannot be disabled.
Constellation tracking: Touch this parameter to choose
which constellations to receive (GPS, GLONASS,
Galileo, SBAS, BeiDou, QZSS). By default, all
constellations are used (enabled).
Debug Data Recording: Enable or disable the automatic
recording of ATL data (debug data). Enabling this
function makes sense only if Spectra Precision
technical support requires to do so. Otherwise keep it
disabled. Debug data will be saved as an
ATL_yymmdd_hhmmss.log file stored in folder:
