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
