Quectel LC79D GNSS modules deliver improved precision so small eMobility vehicles can comply with sidewalk restrictions

Release time: June 1, 2020  Source: Quectel  Click: 349 times

As new legislation is planned in markets across the world to prevent eMobility vehicles such as eScooters and eBikes being used on sidewalks and restricted in areas such as parks, the need to accurately position vehicles has never been more important. Inaccurate positioning will lead to intrusive interruptions to users' journeys and, for eMobility companies in some jurisdictions, licenses to operate may not be awarded if they cannot demonstrate they can enforce compliance on their vehicles.





Very high levels of precision are therefore required if eMobility companies are to be able to demarcate sidewalks from roads. Location is also needed to enable users and eMobility companies to find vehicles in the first place. A bad user experience starts with a struggle to find a vehicle and this is particularly difficult in urban environment where eMobility vehicles can be left between parked cars, behind street furniture or in underground parking garages. Inaccuracies in location of ten meters or more can get experiences off to a bad start.


What's needed is an approach that enables very high accuracy of positioning, but eMobility vehicles present challenges in accommodating the needed technology.  For cars, it's simple. GNSS modules can be installed with unconstrained access to power, very few limitations on form factor and the easily incorporated externally mounted antennas. For smaller, lower value vehicles, such as eBikes which can cost as little as US$400, the deployment situation faces several issues.


The technology utilized must combine low power demand, a viable pricepoint and a combination of powerful positioning technologies all within a small form factor. These difficulties are added to because eMobility vehicles suffer from vibration and signal reception being obscured by the rider themselves.

This is why Quectel has launched our LC79D GNSS module. Unique in the market, the module ticks all the boxes when it comes to small eMobility vehicles because it offers L1 and L5 satellite capability and enables fusion of those signals with data from other sensor data such as dead reckoning information. Combined, these capabilities deliver the precision eMobility companies need while enabling them to comply with emerging regulation and to deliver a superior user experience.


Quectel LC79D modules are in production with samples and developer kits available now.
