DEWA SAT-1 Successfully Transmits 2,690 MB Of Data To Ground Station Since Launch

Dubai Electricity and Water Authority (DEWA) has reported that its nanosatellite, DEWA-SAT 1, has sent 2,690 megabytes of data to the ground station since its launch in January 2022. This 3U nanosatellite facilitates direct communication through its onboard Internet of Things (IoT) system, using LoRa technology for long-range, low-power wireless connections. Data security is maintained through DEWA's encryption standards.

DEWA's Space-D programme aims to integrate nanosatellites with ground-based IoT networks for remote asset monitoring. This initiative supports the digitalisation of power and water networks, enhancing planning, operations, and maintenance across various divisions. The programme also aims to reduce costs and maximise returns on DEWA's investments while promoting knowledge sharing and training for Emirati staff.

Saeed Mohammed Al Tayer, MD & CEO of DEWA, emphasised the utility's commitment to adopting Fourth Industrial Revolution technologies to develop smart infrastructure. He stated that DEWA is the first utility globally to use nanosatellites for improving electricity and water network operations. This innovation boosts operational efficiency and asset management.

The nanosatellites grant DEWA full control over data via a ground station located at the Mohammed bin Rashid Al Maktoum Solar Park's Research and Development Centre. Skilled Emirati operators manage this station with advanced training. As part of the Space-D programme, DEWA launched two nanosatellites: DEWA SAT-1 in January 2022 and DEWA SAT-2 in April 2023.

The nanosatellite technology is utilised for various monitoring tasks within DEWA’s assets. It tracks power factors and frequency in low-voltage rooms, monitors water pipelines for temperature, pressure, and flow anomalies, measures weather conditions like air temperature and humidity, and collects power quality data from remote substations.

In collaboration with partners, DEWA has published seven research papers exploring use cases for DEWA SAT-1. These papers advance understanding of direct-to-satellite communications using LoRa protocols. The research contributes significantly to the field by detailing practical applications of this technology.

The Space-D programme represents a significant step forward in integrating space technology with utility services. By leveraging nanosatellites for monitoring and data collection, DEWA enhances its infrastructure's efficiency while fostering innovation within its workforce. This approach not only optimises operations but also supports sustainable development goals.
