PPLICATION
The MULTIPLEX GPS for M-LINK receivers (hereinafter
"GPS") has been developed exclusively for modelling
applications. It is prohibited to use the unit for industrial
applications or in man-carrying equipment or vehicles.

ASICS MEASURING PRINCIPLE
The MULTIPLEX GPS for M-LINK receivers provides a
means of obtaining interesting information direct from your
model.
At last you can actually see values such as the model's
current airspeed, its altitude above the launch site, and its
distance!
It is also possible to obtain values for other individual
parameters such as the total distance covered by the
model, and various angular information. Warning thres-
holds can be set on the GPS, and a variety of minimum,
maximum and average values can be displayed.
The GPS is based on the same measuring principle as
satellite navigation. It exploits the civilian service of the
U.S. Global Positioning System "GPS".
The measurement of position and speed by means of
GPS is based on more than 24 satellites which circle the
world on precisely determined paths, each orbit taking 11
hours and 58 minutes. Each satellite contains at least one
extremely accurate time-base (atomic clock), which is
monitored and synchronised by fixed stations on Earth.
The receiver in the MULTIPLEX GPS also contains a
clock which is synchronised to the atomic clocks in the
satellites. Each satellite transmits a signal to Earth using a
pre-determined pattern which is known to the MULTIPLEX
GPS receiver.
By measuring the timing of the individual signals it is
possible to determine the distance between the satellites
and the receiver; provided that the position of the satel-
lites is known, this makes it possible to establish the
position of the receiver on the Earth's surface.

OMPATIBLE OUTPUT DEVICES
The basic functions of the GPS (default settings,
can be used without any configuration work provided that
one of the following transmitters is used:
ROYALevo and ROYALpro transmitters,
fitted with M-LINK technology
Transmitters equipped with the MULTIPLEX
Telemetry-Display (# 4 5182).
The GPS can also be operated in conjunction with the
following transmitters after completing an individual con-
figuration process:
COCKPIT SX M-LINK transmitters
(firmware version V3.06 and later)
Before using the GPS with a COCKPIT SX M-LINK it is
essential to set address values in the range 0 to 7 on
the GPS itself. It is also necessary to configure the
GPS for this application.
With the MULTImate (# 8 2094) or the "MULTIPLEX
Launcher" PC program (available as a free download from
the MULTIPLEX website (essential accessory: USB PC-
lead, UNI (# 8 5149)) the GPS can be configured easily
and conveniently to suit personal requirements (
