RTCM
RTCM corrections are received by the VBOX 3iS via a
Racelogic telemetry module and a locally placed Base
station. Contact Racelogic or your local agent for more
details.
DGNSS Rate
• 9600
• 19200
• 38400
• 115200 (default)
This setting configures the DGNSS baud rate.
To make sure that VBOX 3iS receives the DGNSS
correction signal, you must set the correct DGNSS rate.
All Racelogic blue boxed radios use 115200 kbit/s,
and Satel grey boxed radios use either 19200 kbit/s or
38400 kbit/s.
Note: Increasing this value will reduce the number of
satellites the VBOX will be able to use.
Elevation mask
10 (default),15, 20, 25
This setting lets you change the elevation mask, which is
selectable from 10 to 25°.
f the testing area has nearby trees or buildings, you may
benefit from increasing this value to reduce the effect of
multipath.
