SBAS over South Africa delivering outstanding performance

NSL have successfully demonstrated outstanding navigation and positioning improvements for different user communities across South Africa through the use of a new augmentation to GPS.

A new SBAS (Space Based Augmentation System) signal has been transmitting over South Africa immediately providing satellite navigation GPS users with improved accuracy and safety. The ambitious and rather audacious initiative has created an operational system within a 9 month period by developing, installing, implementing and operating GPS reference stations, SBAS processing software, signal uplink systems and safety control systems. NSL are an integral part of the Avanti-led partnership, providing reference stations (our SAGE receivers), uplink control systems and running user community demonstrations.

Set up for the SBAS Africa drone trialsNSL carried out demonstrations for the drone/UAV market and the geomatics/GIS community showcasing the outstanding accuracies of 50cm and better that were being realised by the system.

The drone trials were carried out by NSL and supported by South Africaan company Haevic.

 the test flights, prepared the drones for the additional equipment and provided market expertise. Trials were performed between the dates of 9-16 March 2016 using three different drones at different locations; Potschefstroom and Klerksdorp in North West Province and Koekenaap in the Western Cape province of South Africa.

 

 

GIS trials were carried out in Cape Town in April 2016 by NSL using GIS quality GPS receiver. Real-time mapping activities were demonstrated, again, at the several decimetre level that is suitable for GIS data collection and smaller scale topographic mapping. 

The SBAS-Africa project (http://sbas-africa.avantiplc.com/) 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).
