Hyderabad: Are you among those who often misplace something and then spend time searching for it? For such people, here is an IoT solution which is a low-cost tool and helps you track your asset.
Researchers from the International Institute of Information Technology Hyderabad (IIITH) have developed a novel localisation approach that is Global Positioning System (GPS)-free and uses the LoRaWAN technology which will provide the location data of the asset.
The new technology has been presented in a paper titled ‘Feasibility of Standalone TDoA-based Localisation Using LoRaWAN’ that was published at the International Conference on Localisation and GNSS (ICL-GNSS).
According to Principal Investigator of PATRIoT lab, IIITH, Dr Aftab Hussain, the biggest challenge for engineers in devising a localisation approach lies in synchronising the clocks across the satellites. Currently, synchronisation is achieved via highly sophisticated atomic clocks onboard the satellites. The method which is based on the Time Difference of Arrival (TDoA) – a well-established geo-location technique can locate a signal source from the different arrival times at three or more receivers. “Our method can even be used on Mars where there is no GPS,” Dr Hussain said in an IIITH blog posted on Friday.
The proposed technique which is based on LoRaWAN technology can be replicated with any other wireless technology as well.
According to researchers, currently, the best location accuracy that is being reported for TDoA when the gateways are synchronised using GPS is of the order of 300-500 m. However these researchers have shown a maximum error of around 23 m over an area of 8.6 km.
With a patent filed, a number of companies were evincing interest for commercialising the new technology, the researchers said.
