The network consists of the [[ISRO Telemetry, Tracking and Command Network]] (ISTRAC), augmented by a fully steerable {{convert|18|m|ft|abbr=on}} and a {{convert|32|m|ft|abbr=on}} DSN [[Antenna (radio)|antenna]] which improves the visibility duration when compared with the existing ISTRAC system.

The two antennas at the [[Byalalu]] complex have built-in support facilities. A [[fibre optic]] link will provide necessary communication link between the DSN station and SCC/NCC/ISSDC. The 18 m antenna is provisioned to receive two downlink carriers in [[S band]] and two carriers in [[X band]] ([[Right circular polarization|RCP]] and [[Left circular polarization|LCP]]), whereas the uplink is either RCP or LCP. It has a [[G/T]] of 30/39.5 dB/k (45° elevation, clear sky) for S/X-Band.{{clarify}} | The two antennas at the [[Byalalu]] complex have built-in support facilities.
