SBAS AFRICA Alive and Kicking

SBAS Africa is transmitting a live signal over the Republic of South Africa.  Centred at the L1 frequency, the signal contains modulated data that augments GPS position and navigation providing accuracy and saftey improvements over standard GPS.  In most cases, no additional hardware is used as SBAS (Space Based Augmentation System) is a recognised aviation standard that is already implemented in many GPS receivers.  The SBAS Africa signal is transmitted over the Artemis satellite on satellite PRN number 130.

NSL have developed and installed our SAGE GNSS reference stations, have participated within the ground uplink station safety hardware, and will be providing demonstrations to different user communities. Click on the gallery below to see a slideshow of the installations.

The SBAS-Africa project ( is an industry led initiave co-funded by the UK Space Agency (UKSA) under the International Partnership Space Programme (IPSP) has been made possible by a collaboration between the South African National Space Agency (SANSA) and the UK Space Agency (UKSA). The goals have been realised through the highly successful partnership between Avanti Communications, GMV, NSL, Pildo Labs, Adroit Economics, University of Bath, TAS UK, the South African National Space Agency (SANSA), and Ghana Council for Scientific and Industrial Research and the Agency for Aerial Navigation Safety in Africa and Madagascar (ASECNA).
