TCI International, Inc. products

The TCI Model 802C provides field-proven DF and signal acquisition in an integrated solution for COMINT applications. The 802C is based on an open and flexible client/server architecture that combines fast wideband signal search and direction finding with a complete set of signal analysis tools, including classification, decoding, demodulation and recording. It simultaneously supports automatic and manual signal intercept missions.

TCI’s Model 709 is the next generation Compact Spectrum Monitoring System (CSMS) to detect and locate modern signals of interest for spectrum optimization, interference mitigation, public safety, and national security missions. The 709 leverages TCI’s 50+ year legacy of designing, deploying and maintaining the foundation for modular and scalable monitoring networks. The 709 provides high system sensitivity, low phase noise and high dynamic range to maximize system coverage and ITU measurement capabilities. The result: fewer systems required for monitoring and geolocation across large areas.

The demand for spectrum bandwidth continues to rise as the number of wireless devices increases. Advances in wireless technology provide broader, more complex signals which compels Regulators to license broader bandwidths to alleviate crowding of traditional frequencies.

Evenlode is a series of equipment providing capability for a range of Information Exchange Requirements; equipment may be deployed for air, ground and maritime applications. Evenlode is offered at three levels of complexity with a defined upgrade path. Upgrading from Evenlode I to Evenlode II to Evenlode III uses the previously installed hardware.

TCI has developed two standard layouts for van-based MMS for up to 3.5 tons GVWR. These layouts are similar and only differ in the operator seating and desk arrangement. Layout L has one operator desk installed on the partition wall and one desk on the sidewall. Layout I have both operator desks installed on the partition wall, which makes more storage space available. The type of layout chosen will depend on customer preference and the anticipated mission types. Having both operator positions facing forward may be more convenient for on-the-move operations, while the L shaped layout provides more operator space during standing monitoring operations.

Most communicators are well aware of the problems associated with “close-in” HF communications. Frequently it is easier to raise a station 2,000 km away than one’s base of operations 100 miles distant. To a large extent, the problems of short-range communications are related to inadequate antenna performance.

The 503 provides directional coverage over a 120° azimuthal sector. At the higher frequencies, most frequently used on long paths, the phase center of the structure is elevated, giving increased gain and lower take-off angles. This results in increased signal strength on long paths.
