Stratign offers the most advanced solutions for Portable and Manpack H/V/UHF interception and Direction Finding and automated analysis.

These are smaller and light weight systems which are carried in a backpack by the operator and can be used to monitor and locate transmissions while on the move or at halts. They can carry out operations of search, detection, measurement of parameters, direction finding, recording, technical analysis and classification.
The H/V/UHF Monitoring and DF System can be used in various scenarios depending up on the mission requirement. The man-portable or manpack systems are carried on the backpack of a soldier or are transported in smaller man-portable sections. The man-portable ones are taken to the intended locations and deployed for shorter durations of operations, and it helps in carrying out monitoring and DF of the radio transmissions in that area. These portable stations can also work in tandem with our Static or Mobile solutions.
Stratign also offers a fully Automated Spectrum Monitoring System (ASMS) which allows for networking of all Monitoring and DF Stations and are centrally tasked and controlled from a Control Station. This helps in carrying out radio spectrum analysis over a complete Zone or even the Country.
The operation of the system does not require deep knowledge of the radio communication and provides an excellent platform to intelligence agencies for obtaining valuable data intelligence from radio networks which are used by criminals and terrorists.
