The Satellite Instructional Television Experiment (SITE) and the Satellite Telecommunications Experiments Project (STEP) programs, organised by the Indian Space Research Organisation (ISRO) in collaboration with NASA and P & T (Govt. of India), played a pivotal role in driving the advancement of indigenous telecommunication technology.

Within the framework of these programs, two antennae were strategically installed in Delhi and Madras, serving as communication hubs through satellites such as ATS-6 (U.S.A.) and SYMPHONIE (FRANCO-GERMAN), and later the APPLE Satellite. The responsibility of designing these antennae was entrusted to TCE.

TCE’s scope of work encompassed the comprehensive design of the antenna system, including the reflector, mount with associated drive systems, and foundation. Additionally, TCE was involved in the preparation of fabrication drawings, pre-bid vendor appraisal, procurement, inspection of components, and expediting the manufacturing program. The company also played a crucial role in troubleshooting during installation.

In 1976, TCE further contributed to the project by extending the dish size from 9.5M to 10.7M to ensure compatibility with the SYMPHONIE Satellite.

Subsequently, TCE continued its involvement in shaping the telecommunication landscape in India. The company designed and supervised the fabrication of various landmark antennae, including a 6.1 MT truck-mounted antenna, a 6.1 M Antenna at Andaman, a 3M Emergency Communication Terminal (ECT), a 9.5 M S-Band Antenna, a 136/240 Hz Telemetry Antenna, a 14M MCF Antenna in Hassan, and more.
