MicroNet-PSTR (Personal Secure Tactical Radio) enhances the functionality and performance in the combat environment, ensuring reliable connections between tactical units in the field and their command-and-control centers. This digital, low-cost, lightweight radio employs reliable ciphering encryption technology. The unit's small dimensions allow it to fit in a sleeve or front pocket, and it benefits from the use of advanced Low-Probability of Intercept (LPI) and Low-Probability of Detection (LPD) waveforms that transmit and receive voice and data simultaneously to enable communication in a range of combat scenarios.

• Automatic data exchange and positioning of group members using GPS
• Bluetooth interface for data transmission to a personal computer, Android tablet, or other equipment
• Remote radio software destruction if the unit is lost
• Automatic reporting and transmission of SMS and position data
• Command Android tablet for use by the group leader to rapidly set up required parameters
• Data relay through another terminal to extend the radio network's operational range
• Highly secure voice and data encryption
• Low Power transmission reduces the radio signal's range, making it harder to detect or intercept

TacMap SW package:

• Real-time processing of group members' positions on the map using GPS
• Location of unit members and neighboring units (within the general radio network)
• Creation and transmission of directions and coordinates of the target to all members
• Sending and receiving of short messages
• Display of third-party targeting and intelligence data for the sector
• Execution of search and rescue operations

LPD & LPI:

The Low Probability of Detection (LPD) technique implemented in MicroNet-PSTR ideally suits covert military operation scenarios. This is achieved by using the special waveform and relatively low transmit power. As all data and voice are encrypted based on AES-128 and AES-256 standards, MicroNet-PSTR guarantees a very low probability that the communications will be intercepted.

PSTR-5PA Combined Module:

This vehicle-mounted module is a combination of a 5 W power amplifier and 3 dBi omni-directional antenna aimed at extending the operational range and enabling connectivity between the platoon commander and several subordinate group members. PSTR-5PA can be used in cars, armored vehicles, command vehicles, and as a portable device in a backpack.
