Global Navigation Satellite System (GNSS) Innovation Challenge 2021

The GNSS Innovation Challenge is co-organized by Singapore Land Authority (SLA) and Singapore Space & Technology Ltd. (SSTL). The aim of this challenge is to increase awareness of SiReNT technology and utilize it to develop new or integrated systems that tackle specific shortcomings faced by society.


This year’s challenge hits close to home for many as it aims to help the elderly, people with special needs and pets. Many of us can empathize with the stress of losing a pet or not being able to contact a family member who needs extra assistance. Thankfully, technology today holds the solution to such problems, and we invite you to be a part of the process in finding it. Compete and show off your knowledge and creativity towards engineering a better tomorrow.

What is SiReNT?

SiReNT utilises differential GNSS technique to enhance the accuracy of stand-alone GNSS positioning to provide precise and accurate data for your positioning needs.

The technique involves the simultaneous operation of two GNSS receivers, one that is stationary with known coordinates (reference station) and another that’s roving around making position measurements (roving user).

At the reference stations, differential GNSS correction data is calculated and transmitted to the roving user. The autonomous GNSS positioning accuracy of 5 to 10 meters can be greatly improved to mere centimeters in real-time using the differential GNSS technique.

Challenge Statement:

Design a wearable solution using the SiRent differential GNSS service(s) provided by SLA, to enable the tracking, monitoring and care for one or all of the following:

  • Elderly
  • Persons with Special Needs
  • Pets


  • Students currently in Junior Colleges/Polytechnics/Universities
  • Groups of 3 to 5
  • Must be studying in an Institution based in Singapore
