Low cost, lightweight system for instant tasking of cubesats and small LEO satellites demonstrated by Inmarsat and IQ spacecom

Successful test confirms Inmarsat technology and IQ spacecom product, launched at ILA Air Show in Berlin

Inmarsat, the world leader in global, mobile satellite communications has launched InCommand with a transceiver from IQ spacecom, a division of IQ Technologies for Earth and Space GmbH of Germany at the ILA Air Show in Berlin (Hall 6 booth 432). The ELERA-powered InCommand capability from Inmarsat enables instant commanding and telemetry on-demand for low Earth orbit (LEO) satellites.

InCommand provides a global tasking capability via Inmarsat’s ELERA L-band GEO satellites using IQ spacecom’s low-cost and low Size, Weight and Power (SWaP) transceiver for cubesat and smaller LEO satellites.

The low-cost XLink-L receiver and transmitter, which weighs 200 grams (7 ounces) is ideal for cubesat operators. The InCommand system will request dynamically Inmarsat L-band capacity, globally in real-time, for tasking and commanding cubesat and smaller LEO satellites via Inmarsat’s GEO network. Even the polar areas are in line of sight for the GEO-LEO link.

A successful ground test took place in May 2022, using an adaptation of the IQ spacecom heritage unit, XLink‑S transceiver, adapted to Inmarsat’s L-band ELERA network enabling two-way communications from an operator to a GEO satellite to the ground-based transceiver and back. This successful test will be followed by an in-orbit demonstration.
