Introduction
depending on whether or not a projection is defined in the
local coordinate system used),
If the receiver is a rover, the displayed position will be the last
computed position. The coordinates will be local (“LOC”)
only if the rover receives specific RTCM messages from the
base describing the local system used by the base.
If the receiver is a base, the displayed coordinates are set
ones (not computed ones) representing the WGS84 or local
reference position assigned to the base. See screen example
below for a rover delivering WGS84 coordinates.
The upper line contains the same information as in the upper
line of the General Status screen.
A new press on the Scroll button will take you to the ATL
Recording screen (see below). If however the receiver is fitted
with a radio receiver or is connected to an external radio
transmitter, an additional display screen will show up before
pressing the Scroll button takes you back to the ATL
Recording screen.
The possible two screens show the current radio settings:
• First line: Serial port used, “Rx” for radio receiver or “Tx”
for radio transmitter, radio type (ADL). Extra-parameter for
“Rx”: Power status
• Second line: Channel number, carrier frequency
• Third line: Protocol used (Transparent, Trimtalk, DSNP,
etc.), airlink speed
• Fourth line: Squelch setting (medium, low, high). Extra-
parameters for Rx if a Pacific Crest: “FEC” if forward error
correction enabled, “SCR” if scrambling enabled.
Modulation type (GMSK, 4FSK). The fourth line will be
