New Contract Continues TCI Development of Thai National Radio Monitoring System

Fremont, CA – The National Broadcast and Telecommunications Commission (NBTC) of the Kingdom of Thailand has awarded TCI a contract for 32 remote Radio Monitoring stations and four Operator Control Centers.

The TCI offer, which earned the highest technical score in the bidding competition, involves responsibility for supply, installation, testing, training and monitoring at sites in four administrative regions of the country.

The 32 remote stations to be provided under the contract are fixed sites based on the TCI Model 737 Spectrum Monitoring and Hybrid Geolocation System paired with TCI 643 Dual Polarized Antennas. The system supports monitoring and direction finding across a frequency range from 20 MHz to 3 GHz. All stations can be directed remotely from their corresponding Operator Control Centers. TCI Scorpio ITU-compliant, client-server software will provide state-of-the-art, graphic tools for the control of spectrum monitoring and geolocation activities. This project continues TCI’s legacy in the development and installation of innovative, field-proven hybrid precision geolocation technology. TCI’s Model 737 combines ITU-compliant spectrum monitoring and direction finding with time distance of arrival (TDOA) techniques in a compact, emitter geolocation solution that meets the demanding requirements of regulatory agencies worldwide.

This contract builds on TCI’s previous contributions to the continuing development of Thailand’s National Radio Monitoring System. In a prior phase, TCI supplied 13 remote stations that now keep watch over the spectrum in the country’s Northern and Eastern regions.
