The Square Kilometre Array (SKA), with the aim of achieving a collecting area
of one square kilometre, will be the world's largest radio telescope. A
scientific collaboration between 12 countries (with more to join), it will
consist of one Observatory with 2 telescopes located in South Africa and
Australia. The telescope deployment is planned in two phases, but even in its
first stage (SKA1) it will already enable transformational science in a broad
range of scientific objectives. The inclusion of SKA1 in the Global VLBI
networks (SKA-VLBI) will provide access to very high angular resolution to SKA
science programmes in anticipation of the science to be realized with the full
telescope deployment (SKA2). This contribution provides an overview of the SKA
Observatory VLBI capability, the key operational concepts and outlines the need
to update the science use cases.Comment: 11 pages, 6 figures, conferenc
