3 General Information

The RHOTHETA direction finder system RT-600 Light is designed to receive and locate emergency

signals and special application signals on the international distress and application specific frequencies

in the VHF / UHF frequency range.

The system consists of an Antenna Unit (AU), which is designed light and robust for typical use on

unmanned aircraft.

The RT-600 Light is a modern precision direction finder intended for professional SAR (search and

rescue) and LE (Law Enforcement) purposes, and there are two versions of the RT-600 Light:

•The STANDARD or “A” version receives and locates signals on all international VHF-UHF

emergency frequencies, including marine channel 16 and all COSPAS/SARSAT channels

•The LAW ENFORCEMENT or “LE” version receives and locates special signals tracked by law

enforcement and special organizations, but it also receives and locates signals on international

VHF emergency frequencies including marine channel 16 and all COSPAS/SARSAT channels.

The system is based on the proven and reliable RT-600 system for manned aircraft, which was

designed for usage in harsh conditions, mounted on aircraft or vehicles.

The excellent performance of the RT-600 Light is possible due to our revolutionary patented wide band

antenna and it’s sophisticated bearing analyzing algorithms, which deliver quick and steady

information.

The system is operated over the serial interface. The appropriate communication protocol is described

in the reference document (please s. Ref. [1]).

4 Installation

4.1 Antenna unit

A convenient position of the monopole bearing antenna is crucial for good bearing results. The antenna

needs an effective ground connection to the body of the aircraft or to the roof of the vehicle. If there is

no metallic mounting surface available, a metallic sheet or similar (e.g. net) with connection to ground

has to be applied first between aircraft-body and antenna.

For optimal function of the direction finder it is recommended to use a metallic ground plane with a

minimum diameter of 470 mm.

In the hatched area, the antenna touches the body of the

aircraft

/ vehicle

. In order to obtain a good ground

connection, the surface of the body should be bared.

(Measuring unit [mm])

8 x holes for mounting the

antenna unit to the

aircraft / vehicle.

Fig 2) Antenna Mounting Drawing, all dimensions are in [mm]

For the electrical and data connection, the antenna should be connected to the aircraft by a suitable

cable (corresponding to the used Control Unit). The mating connector is included in the scope of

delivery. For the pinout description please s. chapter 7.2 Interface.

4.2 Influence of antenna location and environment on the bearing

accuracy

The bearing accuracy of the direction finder antenna unit is severely influenced (comparable to an

airspeed sensor) by the environment. For comparison, a perfect high quality speed sensor will not

indicate the true airspeed, if this sensor is interfered by strong turbulences.

The direction finder antenna unit acts as a sensor for electromagnetic waves. In the near field of this

antenna unit, any conductive (e.g. metallic) obstacle will influence the incoming wave field and create

reflections which decrease the bearing accuracy. These are general physical limitations concerning all

types of direction finder systems.

Note

To achieve the best bearing results, it should be considered that the antenna unit is installed as far

away as possible from any other vertically polarized conductive structure. If possible, there should be

no reflectors within an area of 2-3 feet (0,5 – 1 m) around the antenna unit.

Fig 3) Worst case example of the installation

In this example, the antenna unit is located too close to the cable cutter of the helicopter. This cutter

will produce strong reflections, especially as the length is equal to Lambda/4 within the VHF airband

and the direction finder system will not work properly.

5 Configuration

5.1 Mounting

The RT-600 Light can be mounted in a “top”-position (e.g. roof of the vehicles) or a “bottom”-position

(e.g. bottom of the aircraft).

The mounting position is crucial for the correctness of the bearing results.

The mounting position has to be adjusted over the mounting parameter of the serial interface data

protocol (for data protocol please s. Ref. [1]).

Based on this, the bearing is calculated considering the angle of incidence of the wave and the

mounting position of the antenna. This setting is crucial for correctness of the bearing results.

To guarantee a correct configuration and performance of the system, the user should verify – and

change if necessary – the mounting parameter via the serial interface data protocol by setting the

appropriate byte (for detailed information please s. Ref. [1]).

5.2 Offset of Bearing

The RT-600 Light has to be mounted on the aircraft in the way that, the 0° - marker ("North"-marker) is

on the longitudinal axis of the aircraft and points in the flight direction. If the antenna cannot be

mounted (for different reasons) in such way, the deviation correction has to be done via the setting of

the appropriate byte in the interface data protocol (please s. Ref. [1]). The offset is adjustable from 0°

to 359° (e.g. -15° = 345°).
