Transportable and Portable Means

The portable (transportable) automated radio monitoring equipment is based on standard modules, which are also used in fixed, mobile and handheld equipment. They are designed for transportation by vehicles to the deployment area or for carrying by one or several operators. These stations can be deployed in fixed workstations, temporary workstation and on the open ground. The equipment is not intended for operation on the move. There are some limitations in terms of weight, power consumption and dimensions. If required, the equipment can be powered from a standalone power supply.

Technical means have the same operating frequency range, dynamic range parameters, spectrum analysis performance, and direction finding speed as the fixed equipment does.

The root mean square figure of direction finding and field sensitivity of direction finding listed in the Catalogue are determined by the methods, relevant standard test procedures considered in guidelines ITU-R SM.2060 and SM.2096, ITU Handbook “Spectrum Monitoring”, Geneva, 2011 , and in ITU-R SM.2125 report. For each direction finder, standard sensitivity is additionally specified being determined as its mean value in the specified frequency range for a group of products.

The direction finding equipment is provided with navigation systems, which support computation of geographic coordinates and orientation of the antenna system, execute automatic reference of the direction finders to the north direction.

Portable and transportable means can be provided with an integrated diagnostics system of state and operation parameters of modules and units. Transmission of diagnostics results during operation in automated systems is carried out on the basis of standard protocol SNMP.


  • Equipment of portable (transportable) stations has small dimensions and weight below 50 - 100 kg. It makes possible to carry the equipment to hard-to-reach area without mechanical transport means.
  • The station includes automatic direction finders based on two-channel panoramic digital receiver, providing for correlative interferometer DF technique. This technique is the most effective in case of interferences occur. It provides for high accuracy and field sensitivity.
  • Radio monitoring equipment of the stations operating in 9 kHz - 18 GHz frequency range provides full-scale radio monitoring, including quick search of new signals, their recording and technical analysis, automated direction finding, localization of emitters with their mapping
  • In case of autonomous operation, powering is provided from built-in batteries, standalone power units or vehicle battery with voltage ranging from 10 to 32 V
  • It is possible to install the equipment at unprepared sites with minimal (within 20 minutes) time of deployment and removal of all workstations of the station
  • It is possible to operate antenna systems and radio receiving equipment in severe climatic and natural conditions (including high mountain areas, strong winds and heavy precipitation) without any additional preventive measures
  • Software packages support standalone operation, operation as a part of automated spectrum monitoring systems (ARMADA, AREAL, etc.), remote control and data exchange over radio channels, wired and fiber optic lines
  • Power supply from portable electro generator, external AC mains or vehicle on-board DC.
