LETVIS^® MON
system is intended for creation of time-synchronised voice/data/video records, archiving of recorded files and their retrieval for time-synchronised replay or data reduction without interrupting the recording process. LETVIS® MON is to be used for critical applications where the data and signals recorded are replayed with precision time synchronization.

LETVIS^® SDAA
enables a substantial improvement of multi-sensor data processing accuracy. Surveillance Data Accuracy Analysis (SDAA) system was developed in compliance with EUROCONTROL standards. The system is designed for accuracy testing of surveillance radar systems, multi-radar data sources or passive surveillance systems before putting them into operation or for monitoring of systems' performance when in operation. It can be used for PAR testing, as well.
