S-Band TTC Transceivers : Popular manufacturers & their product offerings

An S-Band TTC Transceiver is critical communication subsystem used in satellites and spacecraft to establish reliable two way communication with ground stations. TTC stands for Telemetry, Tracking, and Command. S-band supports 2025–2110 MHz for uplink and 2200–2290 MHz for downlink typically. These transceivers facilitate the transmission of telemetry data, reception of telecommands, and tracking information essential for mission control and satellite health monitoring.

Key Features of S-Band TTC Transceiver

• It supports full duplex communication i.e. simultaneous transmission and reception of data.
• It supports BPSK, QPSK, OQPSK and GMSK
• It supports data rates as per applications; lower (9.6 kbps) for basic telemetry and higher (several Mbps) for advanced applications.
• Most of the transceivers are SDR based which allows re-configuration of frequency, modulation and data rate.
• Can be integrated into small satellites such as cubeSats, smallSats etc. due to size and weight.
