TTC-P3 Transceiver

Generic filters

The TTC-P3 is a dual hot-redundant satellite telemetry, tracking and command (TT&C) radio
with two half-duplex VHF/UHF transceiver designed to enable robust and reliable satellite communication.

The TTC-P3 is intended to be used in an antenna diversity scheme, where each channel is connected to orthogonal and cross-polarized antennas. Hereby a good omnidirectional gain pattern can be achieved, which makes signal reception nearly independent of satellite attitude. Careful receiver design provide a noise figure below 2 dB, which, combined with concatenated convolutional and Reed-Solomon encoding, ensure excellent sensitivity. Realizing that interference have proved problematic over certain regions, the TTC-P3 also features a 60 dB out-of-band rejection filter.

On the transmission side, the power consumption is minimized using constant envelope GMSK modulation, whereby up to 50% efficiency is achieved in the PA stage. This makes the TTC-P3 ideal as a low-power backup link. Fully configurable radio beacons allow basic signal acquisition and coarse tracking of the satellite. User authentication is enabled by default, and (optional) encryption is provided as a part of the CSP protocol.
