Marker Beacons Description
The marker beacons are located vertically beneath the localizer course line at distance 150m
(inner marker), 1km (middle marker) and 7km (outer marker) from the runway threshold.
The beacons radiate a 75MHz radio signal with an audio Morse code. The Morse code and
modulation frequency differ for the outer, middle and inner marker. Outer marker transmits
dash code 400Hz, middle marker transmits dash dot code 1300Hz and inner marker dot code
3000Hz.
1.2
Product Type Numbers
The Normarc product numbering system is based on the following three levels:
• System

Transmitters / Modulators
The NM7050 consists of two TX1373A transmitters. The main transmitter is connected to the
antenna, while the standby transmitter is connected to dummy load. A failure in the main
transmitter will cause an automatic change over to the standby transmitter.
The audio signals are generated in the LF circuitry mainly by a Field Programmable Gate
Array (FPGA). A strap field selects Inner, Middle or Outer Marker settings.
An onboard oscillator generates a 75MHz carrier wave which is amplitude modulated with the
System Description

NORMARC 7050
USER MANUAL
MARKER BEACON
audio signal in the Power Amplifier (PA). The PA is capable of delivering up to 4W power at
97% depth of modulation.
Unwanted frequencies are removed by a lowpass filter after the PA.
3.3
Monitors / Transmitter Control
The marker beacon has one or two MO1374 monitor modules depending on model (Table 31).
The MO1374 is mainly a microprocessor based module. It contains the MB software and
forms the basis of the monitor, station control, system maintenance handling and RMS user
interface.
A detection of error in the transmitter signal causes change-over to the standby transmitter.
Failure of the standby transmitter leads to an alarm and optional shutdown of the standby
transmitter.
On a system with two monitor units, both must report error for alarm to be generated (2 of 2
voting). If the monitors disagree, the WARNING and DISAGR LEDs on the front panel is lit.
The MO1374 consists of two submodules:
The RF frontend receives a RF signal from the antenna (or recombining network for dual
antenna system). It demodulates the signal into analogue values propotional to the RF
power, the modulation depth and the morse code envelope. These parameters are digitized
and monitored by the CPU section.
The CPU section includes an 80CI88 CPU, memory, communication ports and an AD converter system.
3.4
Power Systems
The marker beacon can have either one or two PS1375 power modules depending on model
(Table 3-1). The PS1375 is 100W with 120V or 230V AC input voltage and +28V/3.5 A, +20/
2.5A, ±12V/1.25A and 5V/6A DC output voltages. Outputs are short circuit protected. On the
NM7050 B/D the two modules operate in parallel.
The 28V output is temperature compensated to ensure optimum battery charging. It gives
26.4V at 50°C and linearly increase to 29.6V at -30°C.
The backup battery is an external 24V battery. The battery gives a backup time of 6 hours,
and have external charging possibilities for longer backup time. This battery is automatically
brought into circuit on mains power failure. The charging time is approximately eight hours
with one PS1375 and five hours with two PS1375.
3.5
Remote control system
The remote control unit is used in the tower or in the technical control room. It has indicators
for operating status as well as detailed warnings and an aural alarm device with reset. It can
control equipment on/off and change over, and has an Access Grant switch to allow/inhibit
remote control from the RMM system.

Figure 3-2 The NM 7050 RMM/RMS systems
The centre of the RMM system is a CPU with the RMS core program. The RMS collects measurements and diagnostic data, and makes them available to the user. The collected information allows easy and cost effective maintenance, fault finding and routine reporting. In
addition, system settings are distributed and parameter readings are collected via the RMS/
CPU.
External Personal Computers are used for a user friendly interface to the RMM system. The
equipment has two serial output ports, typically used to connect a local PC and a connection
to a central maintenance facility.

The local keyboard/display allows readings and controls through an LCD display and a sevenbutton keypad. This gives access to the RMM functionality without the need for a PC.
3.7
RMM Access
Access to the RMM system is controlled by multiple hardware and software access controls.
One password is required for each access level, i.e. one password for level 1, two for level 2
and three for level 3. Optional hardware controls may inhibit writing in the upper access levels.
Access level 1
• Readout of all the monitor values, warning and alarm limits.
• Readout of all the maintenance values and warning limits.
• Readout of all the delays.
Access level 2

A 16Ah battery gives approximately six hours backup time with 5-8 hours charging time
dependent on model. For longer backup time an external charger is required to be able to
charge the battery within a reasonable time. An external battery protection circuit (like Normarcs BP 543) has to be connected between the EXT. CHARGER (+) and BATT GND (-) input.
In addition MAINS directly on NM 7050 has to be disconnected. Figure 5-4 shows the connections schematically.

Alternatively the remote control connection is done with a RS 232 interface. The mode is configured on MO 1374, refer to 7.2.3.
Note: The position of RXD and TXD is interchanged from the normal RS-232 layout in the
Remote Control connector. Therefore a special cable must be used for connection to external
equipment.

Antenna
Normarc supplies single and dual antennas, NM 3561 and NM 3562 respectively. The single
antenna may be used for inner, middle and outer marker, while the dual antenna is specially
designed for outer markers. The advantage of the dual antenna is a lower spread in FLYING
THROUGH TIME inside the localizer coverage area. In addition to two antenna elements, the
monitor and distribution network DI 726 is included in NM 3562.

Figure6-2 shows the field strength of the radiated signal directly above the middle marker
antenna. Figure6-3 and Figure6-4 illustrate the field strength above the outer marker
antenna, using single and dual antenna, respectively. The localizer course sector is scetched.
Along an elliptical curve, the field strength is constant. If you look at the diagrams as ordinary
geographical maps, you will see that the dual antenna "field-strength-mountain" is steaper
and more stretched sideways than the single antenna "mountain". This corresponds to a
sharper on/off response on the aircraft's marker beacon instruments.

Antenna NM 3561 / NM 3562 For Ils Marker Beacon
The NM 3561/NM 3562 Marker Beacon Antennas are log-periodic dipoles possessing properties of high gain and directivity, and low side lobes. The performances og the antennas conform to ICAO Annex 10 item 3.1.6, and are such that they are largely independent of
environment factors such as rain, snow and ice, and they can therefore be located at «difficult» sites. The directivity of the antennas can, if required, be even further increased by adding additional elements to the array.
The radiation patterns for the antennas are almost unaffected by the surrondings, and the
antennas are therefore suitable for offset location where tilting of the antennas is necessary in
order to obtain the required signal coverage. (Refer to figure A-1)
Figure12-3, 12-4 and 12-5 shows constant field strenght lines through points in the glide path
(GP angle 3º). The marker beacons are located vertically beneath the localizer course line at
distance of 1050 m (middle marker) and 3.9 nautical miles (outer marker) from the threshold.
The field strengths specified are relative to the maximum level directly above the antenna.
The figures show that for an aircraft travelling at a speed of 50 m/s (96 knots) within the maximum allowable course sector of 6º the duration of the visual indication will be within the prescribes limits. The instrument panel lamp should be adjusted so as to switch on or off at the
levels indicated in the figures i.e. -27 dB to -33 dB for Figure12-3, -11 dB to Figure12-4, and 13 dB to -25 dB for Figure12-5.
The marker beacon antennas are mounted on poles, with the dipoles parallel to the course
line. The rear end of an antenna should be at least 2 metres above the ground.
The NM 3562 antenna comprises two elements, and is fed via a distribution network (DIA 726)
which splits the transmitter power into two equal parts. The network is a coaxial cable hybrid
housed in silumine box together with the monitor network which is used to combine the signal
from the two monitor probes.
