It contains three antenna ports, two of which use SMA connectors and operate across the 2 kHz to 3.2 GHz range and the third uses a BNC connector which operates up to 200 MHz.<ref>[https://www.sdrplay.com/rsp2pro/ SDRplay RSP2 Pro], [https://www.sdrplay.com/rspdx/ RSPdx], (SDRplay)</ref> The SDR module provide enhanced performance with additional and improved pre-selection filters, improved intermodulation performance, the addition of a user selectable DAB notch filter and more software selectable attenuation steps . The SDR module introduces a special HDR (High Dynamic Range) mode for reception within selected bands below 2MHz. HDR mode delivers improved intermodulation performance and fewer spurious responses for those challenging bands. | ||

*Fast search for active radio frequencies (RF surveying), up to 100 channels per second, including mobile communications, ready-made patterns for precise identification (modulation type, pulse type, power). In group mode, the search tasks are distributed among several users and are not duplicated. Found frequencies are memorized for subsequent periodic scanning. Tasks for scanning previously found frequencies are also distributed among several users. This multiplies the productivity of radio scanning. The scanning tasks are performed automatically in the background and do not require the constant attention of the user. The user can analyze the spectrogram and "waterfall" of frequencies, measure power, control the operation of filters, determine the sources of radio frequency interference (RFI/EMC detection) | *Fast search for active radio frequencies (RF surveying), up to 100 channels per second, including mobile communications, ready-made patterns for precise identification (modulation type, pulse type, power).

*The most popular algorithm of use without user participation is automatic scanning of channels, identification of signal type and wave (including pattern recognition by means of Computer Vision), localization of the radio transmission source, identification of friend or foe, and then notification of the user and sending reports to the command server. | |||

The system consists of several groups of iconographic symbols. In many ways it resembles the system of road signs, which have a concise form and are perceived instantly, causing an appropriate reaction. Such a system is perceived much faster than a text or voice command. An example of this is the sign language used in special operations units. Also unlike the voice call session is much shorter, does not overload the communication line, small data packet is not demanding on the data rate, the digital data packet with the control notification of receipt always means only 2 states, that the message is received or not. No problem with message illegibility, lack of clarity in the message. No need to tell who is transmitting the message. This method itself is very concise and eliminates unnecessary information, thus relieving the communication channel and the attention of users. This communication system is particularly important for international contingents and during joint exercises. | The system consists of several groups of iconographic symbols.

We are researching promising options for troop security, such as the use of sensors (detectors) to remotely detect explosive tripwires (booby traps), pressure mines, and improvised explosive devices (IEDs) triggered by proximity. In the future, if successful, we will make such external devices available as an option for attachment via NVG mounts. | We are researching promising options for troop security, such as the use of sensors (detectors) to remotely detect explosive tripwires (booby traps), pressure mines, and improvised explosive devices (IEDs) triggered by proximity.

The comfort of long-term use differentiates the mask from most other devices worn on the head. In particular, the mask is differentiated by its very low breathing resistance while protecting the respiratory organs and very low pressure on the soft tissues of the face and head. To prevent the user from experiencing dehydration, a drinking system is integrated into the mask. The design of the mask protects the user's eyes from direct sunlight and the visor of the mask is tinted. | ||

We have high hygienic requirements for the product. The materials do not cause allergic reactions. Water and dust protection class IP67 or higher. The electronic components are sealed in a rugged housing and are actively cooled with an aluminum radiator on the top of the housing and on the inner surface at the front. The mask has interchangeable elements: 2 air filters, 2 filter covers, 1 face contour seal. The mask can be cleaned with water and alcohol sprays on the outside and inside. We do not recommend the use of alcohol-containing products to treat the transparent visor as this may cause clouding. | We have high hygienic requirements for the product.
