African Space Policy & Strategy: Redefining Satellite Navigation and Positioning in Africa (2)

This is the concluding part of this series

The application of N&P is through non-augmented and the augmentations systems and techniques. The accompanying tech to use is dependent on the needs of each application. The app is dissolved in the report thus:

  1. The non-augmented system includes global and regional systems (GNSS); the global systems are those that provide service all around the world and 24hours a day (GPS, GLONASS, Galileo, Beidou); and regional system like the Japanese QZSS (Quasi-Zenith Satellite System).
  2. Augmented GNSS are those systems that improve the performance of GNSS; they are Satellite-based. Augmentation Systems (SBAS), Ground-Based Augmentation systems (GBAS) and Aircraft Based Augmentation systems
  3.  The augmentation techniques are those that are developed and used to improve GNSS performance such as RAIM (Receiver Autonomous Integrity Monitoring), DGNSS (Differential GNSS), RTK (Real-Time Kinematic) …

Industrial application

N&P usage in Africa cuts across the sectors highlighted by the AUC, and records notable performances. However, there is an ever-increasing need for a regional advancement of prerequisite tools. The GNSS applications available in Africa are PPP, DGNSS and RTK and they are often obtained through private establishments like FUGRO or through local solutions, limiting the reach of the users. Therefore there is a dire need for the establishment of ground stations across Africa to reach minimum requirements.

Infrastructural development

GNSS applications are reliant on several infrastructures to function effectively.

The image above shows that Africa still suffers a lot of infrastructural deficit in different sectors. A lot of machinery, expertise, and equipment are still in need to achieve the global standard. The AUC report carefully highlights this. While some N&P infrastructures exist in Africa under categorisation such as Local Area Differential and Precise Positioning Infrastructure, Local Area Differential and Precise Positioning Infrastructure, Wide Area Differential Positioning Infrastructure, Stand Alone GNSS Reference stations, GNSS Data Processing Infrastructure, Africa still needs more.

N&P development in Africa has a lot of strong areas but still suffers from an infrastructural deficit, inadequate technical know-how, absence of adequate investment and funding, the low adoption rate of innovative techniques due to lack of exposure, to mention a few. The report includes a swot analysis that is displayed below:

Infrastructure Category Primary Sectors Served by Satellite N&P

Infrastructure

Strengths Weaknesses Opportunities Threats
Wide Area Precision Positioning Infrastructure · Maritime

· Agriculture

· Survey & Mapping

· Emerging Technologies (Drones and unmanned vehicles, ITS)

· Capacity to deliver PPP services

· Low-level investment required in-ground infrastructure

· Sparse coverage in Africa. Mainly providing services to the Maritime community (oil & gas, maritime navigation)

· Investment needed by users in equipment and recurrent costs.

· performance challenges in equatorial African regions dues to high scintillation solar activities.

· Continuous upgrades to GPS constellation with new civilian navigation signals and robust system designs.

· Bundling of services through the integration of products now offered by few Surveying equipment manufacturers ( Trimble and Novatel )

· Potential alternative solution will be available through Galileo High Accuracy Commercial Service (HA CS) may render services from Wide Area Precision Positioning Infrastructure obsolete

· PPP services offered through Wide Area Precision Positioning Infrastructure will be widely available through internet streaming as IoT devices increase.

Local Area Differential and Precise Positioning Infrastructure · Maritime

· Agriculture

· Survey & Mapping

· Provides Higher levels accuracy to a limited geographical area for those states that have deployed the infrastructure.

· A cost-effective solution for states seeking to provide positioning services to their citizens.

· readily available technology (GNSS Receivers, modems etc) on the market.

· Readily available human capacity to support the operation of infrastructure (training institutions)

· Rate of adoption of the implementation of GNSS CORS is very slow. Only 14 States out of 54 known to have an infrastructure.

· Existing CORS are sparsely distributed with an average spacing of 100KM.

· Low coverage of CORS network within the majority of States

· Limited optimization of infrastructure usage due to the low level of participation in regional initiatives such as AFREF

· High-level investment needed due to the large density of reference stations required to cover the entire African continent.

· Performance depends on the distance from the user position to the reference station.

· Limited infrastructure to serve Maritime Navigation service providers in Africa.

· Poor access to service due to low levels of telecommunication means

· The CORS infrastructure development is continuously supported by states through the implementation of SDI (Spatial Data Infrastructure) –

E.g Ghana plans to cover the country with over 30 more CORS,

· Continuous improvement of services through upgrades to GPS constellation with new civilian navigation signals and robust system designs

 

This focus of this report is not just to identify problems, but to recommend practical solutions, identify opportunities, and look for areas of development. The above image highlights some of these. The AUC, therefore, is duty-bound to pursue these lapses to the benefit of the continent following their stipulated guidelines and mandate.

Gap analysis

The report includes a gap analysis that borders around:

  1. Assessment of N&P gaps versus AU flagship programme on space:

This includes the identification and status of indicators, the definition of reference baseline and measurement of gaps, and qualitative gaps assessment.

2. Assessment of gaps in terms of technology and infrastructure:

This includes the quantitative evaluation of corresponding gaps in terms of N&P infrastructure and technology.

The practical guidelines for identifying the status of implementation in the report are:

  1. Leveraging space-derived benefits
  2. Strengthening research, development and innovation
  3. Developing and using human capital
  4. Institutionalising a corporate governance structure
  5. Adhering to regulatory requirements
  6. Building critical infrastructure
  7. Fostering regional coordination and collaboration
  8. Promoting strategic partnerships
  9. Funding and sustainability

 The gap analysis, however, shows that most of the N&P domain indicators are still at an incredibly low ebb, scoring an average of 2 out of a possible 5 in performance indicators. This identification by the gaps analysis reinforces the importance of assessing performance to know areas that need improvements, and apparently, all included regions are in dire need of improvement, especially in the first ten years of implementation, as the failure or success of these first ten years will tell emphatically on the overall success of the African Space Policy and Strategy in the long run. A visual representation of the indicator performance is included below.

The reference baseline indicates the projection for the activation of particular infrastructural and long-term collaborative continental-wide achievement of N&P systems in Africa. Unfortunately, this also shows a slow advancement as the first ten years deadline of 2018 – 2028 draws nearer. Technology in response to user needs is at a low ebb, while performance also drags across different sub-region.

Continuously Operating Reference Stations (CORS) are also not up to the required standard. While each sub-region continues to work very hard to meet up, it is important highlighting progress achieved so far, so that governments can sit up and work even harder and faster.

Asides CORS, several cogent infrastructural deficits like GNSS, IGS stations, Array GPS stations, Seismic Stations, etc. are being worked on around the clock. One can only hope that all countries and sub-regions are able to meet the set deadline in order to foster African progress in space tech without having to leave some countries or regions behind.

Implementation plan

The AUC plan works on a deadline based roadmap, having a short term, medium-term and long term execution time frame. The first ten-year implementation Plan of AUC presented targets for each objective and priority area of Agenda 2063 on the timeframe 2013-2023. This report aims at an evolution of N&P services at a targeted ten-year period from 2018-2028. The report issues the following as the core focus of Africa for the next ten years of execution:

  • Development of the services and products required to respond effectively to the socio-economic needs of the continent,
  • Development of indigenous capacity to operate and maintain core space capabilities,
  • Development of an industrial ability that can translate innovative ideas from research and development into the public and commercial sectors,
  • Coordination of space activities across member states and regions to minimise duplication, but maintaining sufficient critical mass,
  • Fostering international cooperation within Africa and with the rest of the world as a means of realising the full value proposition of the space sector.

Conclusion

The success of the AUC plan is a collaborative long-term plan with breaks and pauses for assessments. The long walk entails all African countries and sub-regional blocs to walk a similar path and work for the success of the Africa Space Policy and Strategy. The failure of a state is no longer an individual problem but a continental challenge. The survey and gap analysis have indicated where the continent, partners, leaders, research institutions, and other stakeholders need to partner on and cover-up within the given time frame. It is left to stakeholders to either reach the Africa Agenda or miss the opportunity to put Africa at par or even ahead of other continents. There is no better time than now.
