Status information
Skyplot graph
The center of the skyplot represents the antenna position. The skyplot shows all GPS satellites cur-
rently being tracked and – if enabled (under INTERFACES: REFERENCES > GNSS Reference:
GNSS 0 > Edit button > Selected Constellations ) – will also display all GLONASS satellites
(numbered 65 and higher). Note, however, that GLONASS satellites will not be used by
BroadShield. Galileo and Beidou satellites will not be displayed.
Signal-to-noise bar graph
This graph visualizes the signal-to-noise ratio for up to 20 received satellites in real time. The
satellites are numbered by their NMEA ID's (as in the skyplot mentioned above).

Note: The BroadShield GNSS1 reference refers to the SecureSync GNSS 0 ref-
erence.
GPS Time : Time and Day as provided by VersaSync's GNSS receiver.
Position : The position as determined by VersaSync's GNSS receiver.
Satellites Used : The number of satellites currently received by VersaSync. This number
includes all satellites currently received for all enabled constellations (see "Selecting
GNSS Constellations" on page 164). Note that BroadShield uses only GPS signals for
jamming/spoofing detection.
Average C/No : Average signal to noise ratio. An average C/No value higher than 30
can be considered "good".
Note: Even though VersaSync may be configured to track multiple GNSS con-
stellations (see "Selecting GNSS Constellations" on page 164),
uses GPS.
