Economically sustainable public security and emergency network exploiting a broadband communications satellite
The research contributes to work in Rapid Deployment of a National Public Security and Emergency Communications Network using Communication Satellite Broadband. Although studies in Public Security Communication networks have examined the use of communications satellite as an integral part of the Communication Infrastructure, there has not been an in-depth design analysis of an optimized regional broadband-based communication satellite in relation to the envisaged service coverage area, with little or no terrestrial last-mile telecommunications infrastructure for delivery of satellite solutions, applications and services.
As such, the research provides a case study of a Nigerian Public Safety Security Communications Pilot project deployed in regions of the African continent with inadequate terrestrial last mile infrastructure and thus requiring a robust regional Communications Satellite complemented with variants of terrestrial wireless technologies to bridge the digital hiatus as a short and medium term measure apart from other strategic needs.
The research not only addresses the pivotal role of a secured integrated communications Public safety network for security agencies and emergency service organizations with its potential to foster efficient information symmetry amongst their operations including during emergency and crisis management in a timely manner but demonstrates a working model of how analogue spectrum meant for Push-to-Talk (PTT) services can be re-farmed and digitalized as a “dedicated” broadband-based public communications system. The network’s sustainability can be secured by using excess capacity for the strategic commercial telecommunication needs of the state and its citizens. Utilization of scarce spectrum has been deployed for Nigeria’s Cashless policy pilot project for financial and digital inclusion. This effectively drives the universal access goals, without exclusivity, in a continent, which still remains the least wired in the world

Design of a low-cost augmentation navigation system: the United Kingdom's immediate answer to the Galileo Brexit conundrum
United Kingdom’s Brexit from the European Union implies restricted access to the European Global Navigation Satellite System (GNSS) System - Galileo; with no access to the secured and encrypted signal used for defense and government purposes, which is restricted to European Union (EU) members. To mitigate this issue, the United Kingdom can, as a matter of urgency, launch a payload on a national military Communications Satellite to provide Navigation Overlay Services for the United Kingdom territory, surrounding waters and neighboring ally countries to meet the requirements of: Defense systems, Aviation, Maritime requirements and the effectiveness of Location-based Services for Emergencies and Crisis management etc. This paper describes the design of a navigation overlay service system as a hoisted payload on a national satellite and the required supporting ground infrastructure, highlighting various applications, services and solutions

NIGCOMSAT-1R Satellite-Based Augmentation System(SBAS) test bed trial
In October, 2016 China Great Wall Industry Corporation and Spacestar Technology Company Ltd of China entered into cooperative agreement with Nigerian Communications Satellite Ltd on a Satellite-Based Augmentation System (SBAS) performance test and assessment of the Nigerian Communications Satellite (NIGCOMSAT-1R) augmentation System exploiting NIGCOMSAT-1R L Band. This paper examines test bed experimentation conducted in conjunction with partners to validate functional requirements, performance validation of units, sub-systems and systems of both the SBAS payload and ground infrastructure before a pilot project demonstration of capabilities and proof-of-concept nationwide and extension to parts and regions of Afric

Overview of satellite communications and its applications in telemedicine for the underserved in Nigeria: a case study
More than 2000 satellites currently relay communications signals to and fro various locations across the globe for Internet, Broadcasting, Telephony and Navigation and the number is expected to quadruple in the next few years due to the proliferation of Global N on-Geo Satellite Constellations. With the potential to connect people separated by great distances, satellites are now being applied in telemedicine to make healthcare cheaper and more accessible. Nigeria has not been left behind in these efforts and has deployed the NIGCOMSAT-1R Communications satellite to provide telemedicine services to patients with health issues. Internally displaced women and children are globally the worst hit by the unavailability of healthcare services, with 87% of deaths in internally displaced person (IDP) camps resulting from preventable illnesses. This presents a clear need for the adoption of telemedicine in IDP camps to provide Digital Health Inclusion services to the vulnerable citizens. We carried out a satellite-enabled telemedicine medical outreach at New Kuchingoro IDP camp in Abuja, Nigeria. A mobile application that allowed for text, audio, and video communication was employed using internet connectivity provided by the NIGCOMSAT-1R Communications Satellite. A total of 317 patients were attended to over the course of three days, and major issues prevalent in Nigerian hospitals, such as long waiting hours, were minimized. The medical outreach experience demonstrates the advantage of satellite broadband for telemedicine projects. It also proves the urgent need for innovative solutions for healthcare delivery in underserved and unserved Nigerian communities

Digital health inclusion: a pilot study of health services deployment using communications satellite for the underserved in Nigeria
Health service delivery in Nigeria is constrained by: brain drain, insufficient infrastructure and technology, poor and inadequate medical facilities and paucity of medical specialists in rural and remote regions - thus leading to a high rate of “medical tourism”. With increasing mobile phone ownership in Nigeria, mobile technology-based telemedicine has the potential to improve Nigeria’s healthcare delivery with enabling infrastructural facilities. In this paper, a pilot study that uses Nigeria’s communication satellite system for virtual Telemedicine connection between health practitioners and underserved communities using the “one2one” mobile telemedicine application is reported. This pilot study aimed to deploy Nigeria’s communication satellite system to enable virtual telemedicine connection between health practitioners and underserved communities using the “one2one” mobile telemedicine app. Successful deployment of a 1.8m VSAT dish at the pilot clinic and testing showed robust internet connectivity with a time delay of 250ms per hop. Furthermore, the One2one app was successfully installed on health practitioners’ tablets/phone and patients’ phone/tablets. Over 100 patients were treated using the one2one app connected through the satellite internet. The one2one app was highly rated by patients and healthcare providers in terms of usability with the highest score being ease of use 87%. This study shows that Nigeria’s communications satellite can be deployed to support mobile telemedicine as part of the effort to increase access to doctors and specialists in medically underserved areas of Nigeria
