GPS RECEIVER WITH SIMULATED DCF77 OUTPUT
1. General Information
The Global Positioning System (GPS) is a satellite system developed in the USA and based
on the NAVSTAR satellites made by Rockwell. With this system, it is possible to receive ex-
act time information anywhere in the world, anytime.
To meet these requirements, it was necessary to position a total of 24 satellites in 6 almost
circular orbits. The satellites’ orbits are inclined at 55° to the equator with an orbital period
of about twelve hours –corresponding to an orbital altitude of 20,183 km. These satellites
are now in operation. Each satellite has a mass of about 430 kg and contains a transmitter,
a receiver, an antenna, an atomic clock for maximum accuracy and a control system for the
satellite’s functions. The principal applications of the GPS system are for fixing positions and
as an aid to navigation.
2. Operating Principles
Once the GPS system is switched on, it first has to receive and evaluate valid data from the
satellites in its line of sight. This start-up phase may take as little as 2 –3 minutes if recep-
tion conditions are favourable. However, as long as half an hour may be needed if there is a
poor line of sight to the horizon. This start-up phase is also influenced by the configuration
the satellites are in at any particular time. It is impossible to fix a position or obtain time in-
formation with fewer than three satellites. The red LED “GPS IS WORKING...” flashes while
the satellite signals are being received. When the unit subsequently commences continuous
operation, this light-emitting diode only flashes when the number of satellites being re-
ceived falls below three.
It is simple to set up the system and the procedure does not require any particular special-
ist knowledge. The daylight saving time changes (start and finish) and the time zone can be
set using slide switches.
3. Installation and Start-up
3.1 Generals
The high frequency of the GPS signal (approx. 1.5 GHz) means an outdoor aerial is always
necessary for receiving GPS satellite data. The antenna must not have any directional char-
acteristics because it needs to receive data from all directions. Consequently, boosting the
reception characteristics of the antenna by shaping it mechanically as in the case of a para-
bolic antenna, for example, is not a viable option.
This means the signal magnitude at the antenna output is below the general background
noise level. An extremely low-noise pre-amplifier is therefore connected to the antenna in-
put to make it possible to evaluate the signals.
The antenna should have a clear “line of sight” to the entire horizon to guarantee that the
GPS reception will be as continuous as possible. The start-up phase may take a long time if
the reception arc is obstructed by objects or buildings, depending on the configuration of
the satellites. As a result, the antenna should be set up where the maximum possible clear
line of sight to the horizon is guaranteed. In general, the more of the sky you can see from
the installation site, the quicker the GPS clock will be radio-synchronized and the longer it
will remain so.

Installation and Start-up
3.2 Installation site for the antenna
The GPS antenna is located in the control unit housing when the unit is delivered.
Please observe the instructions below if the reception conditions make it necessary to in-
stall the antenna separately. The length of the antenna cable is about 5 m.
Adequate location
(may take several hours)
Good location
(activation in 2-3 minutes)
Poor location
(activation not possible or takes long time)
3.3 Installing the antenna cable
Do not route the antenna lead adjacent to other HF, control or power current cables. Inter-
ference from these cables could disrupt GPS reception because of the extremely low power
of the received signal. Take particular care when routing the antenna cable.
Please observe the following points:
0Do not get the antenna plug dirty and do not damage it. Protect it with plastic foil
before pulling the cable through a wall, for example.
0Do not bend the antenna cable around sharp corners.
0Do not exceed the bending radius.
0Do not squash the antenna cable and do not damage the insulation.

Caution!
Extremely powerful voltage or current spikes may occur when outdoor antennas are
used during thunderstorms. These spikes represent a risk of severe or even irreparable
damage not only to the unit connected directly to the antenna but also to other down-
circuit units.
The unit should be incorporated into the building’s lightning protection system in order
to avoid suffering costly damage and concomitant costs.
The lightning protection system may only be installed by qualified professionals.
4. Electronic connection, DCF- output, Data protocol
Consistent with the products in the REGSys™ range, the GPS receiver is available in two var-
iations for different voltage supplies. (See: Technical Data)
1It is connected using the terminals marked L, N and PE. Only an electrician is allowed to
do this.
The GPS receiver allocates three different output signals.
0DCF Pulse Output at RS232 Level:
A DCF signal, at RS232 level, is output at the DCF and GND terminals. To synchronise,
for example, a REG-DTM per GPS, the GND terminals must be connected to the GND,
and the DFC terminal must be connected to the RXD of a RS232 interface controller.
The settings needed for synchronisation are described in the user manual of the corre-
sponding device.
0DCF Pulse Output at RS485 Level (Timebus)
A DCF signal, at RS485 level, is output at the DCF-EA+ and DCF-EA- terminals. To syn-
chronise, for example, a PQI-DATM via GPS, the devices must be connected as follows:
GPS Radio Clock
PQI-DA
DCF-EA+
“A” to connection X6, No. 47
DCF-EA-
“B” to connection X6, No. 48
GND
“GND” to connection X6, No. 50
The settings needed for synchronisation are described in the user manual of the corre-
sponding device.
Termination of the bus should be carried out as described in the user manual of the particu-
lar device, and is not dependent on the connection of a GPS radio clock to the bus.
0DCF Pulse Output at RS485 Level (Timebus)
A DCF signal, at RS485 level, is output at the DCF-EA+ and DCF-EA- terminals. To syn-
chronise, for example, a PQI-DTM per GPS, the DCF-EA+ terminals must be connected to
the “Time in A”, and the DCF-EA- terminal must be connected to the “Time in B” of the
PQI-D. The settings needed for synchronisation are described in the user manual of the
corresponding device.
0Data Protocol at RS232 Level:
A data protocol for a serial RS-232 port is transmitted via the terminals TxD and GND.
The contents of the data are time, day of the week and date. The data format of inter-
face is set at 9600 baud rate, 8 bits, 1 stop bits, Parity odd.
