The IQ Spacecom XLink-S is an S-Band Transceiver System (SDR) suitable for micro, nano and pico satellites in LEO.
The physical dimensions of the system allow it to fit in a 1U CubeSat and standard CCSDS protocols are used to develop the radio interface and radio protocol. The systems are designed to be deliver downlink data rates with high net payload rates.
A standard CCSDS BPSK with BCH coding is used in the satellite receiver (uplink) for telecommand purposes of the satellites. Alternative uplink receivers in the S-band frequencies are available.
With appropriate FEC encoding schemes, the SDR supports higher order forms of modulation, such as BPSK and QPSK. Data throughput maximization is possible through Adaptive Modulation and Coding (AMC) schemes.
One important feature of the system is the optional availability of two separate Tx channels which can be used to increase the transmit power or redundancy.
Testing & qualification
The company has a DIN EN ISO 9001:2015 certified quality management system.
