Appendix A. Description of RiverSurveyor Live Icons
Bluetooth is a wireless short-range communications technology allowing data transmission
over short distances from fixed and mobile devices. When users apply this method of communi-
cation between their PC or Mobile device and the ADP, a blue icon indicates that Bluetooth is
active, while a red icon represents inactive (icons below). Bluetooth signal strength is indicated
with a green icon square, a full square indicates a strong Bluetooth signal, while squares not
completely filled indicates proportional signal strength.
BT Active BT Inactive
Bottom Track is used to remove vessel motion from measured water velocity to determine the
“true” water velocity, track distance and depth. That is, when you mount the ADP to a vessel,
bottom-track measures the velocity and direction of the ADP/vessel movement over ground.
There are four icons (below) for bottom track quality: blue corresponding to depth and track data
(optimal); yellow means bottom track only depth is valid (functional); red indicates that bottom
track does not have a lock; and the grey icon indicates that the feature is not available.
RTK GPS is the essential GGA GPS fix data which provides 3-D location and accuracy data for
the system. This data string includes: Latitude, Longitude, Fix quality, Number of satellites used,
Altitude as well as many other types of information. There are five icons for RTK GPS, as seen
below, ranging from RTK (Real-time kinematic--blue) to the Inactive (gray). The RTK and DIF
icons will toggle between each other as the GPS acquires a RTK lock. All icons will be blue
when an RTK lock has been achieved.
