•

Position Rate: 1- or 2-Hz position output rate.

•

Store Vectors in Raw Data: With this option enabled, FAST
Survey will

save the computed vectors into the job (into

the RW5 file).

•

Base Receiver Type: You may specify the manufacturer of
the base providing your rover with corrections. This will
ease the process through which the rover can decode
these corrections. If you have no idea which receiver
model is used at the base, select

AUTOMATIC and the rover

will automatically find out the manufacturer of the base
receiver.

•

Use GLONASS: Remember that activating the Use GLONASS
option in ProMark 220 will be effective only if you have
previously set the

Tracking mode parameter in GNSS

Toolbox to “GPS L1+GLONASS L1” or “GPS/GLONASS
L1/L2”. As for the

Use SBAS and Use QZSS options, only

the last setting made is effective, whether you do it from
GNSS Toolbox or from FAST Survey.

•

Send file after config: You may have a number of additional
commands executed (proprietary commands of the

“$PASH” type) when later you tap on

to configure the

receiver. These commands must have been saved to a text
file, for example to a file created using

Equip > GPS Utility

Send command. To select the file you want the receiver to

execute when being configured, tap on the blue button
and highlight the corresponding file name.

• NMEA Output Port: You may ask the rover to output one or

more NMEA messages (GGA, GLL, RMC, VTG, GSV, GSA,

ZDA, GST) on the specified output

port. Once you have

defined the

output port (common to all NMEA

messages), tap on the

Configure button and then, for

each desired NMEA

message, select its output rate (in

Hertz or seconds).

•

Ambiguity Fixing (see table below).

•

Use QZSS: Enables/disables the use of the QZSS (Quasi-
Zenith Satellite System) constellation covering Japan and
the Far East.
