Recently, OPPO announced the launch of its self-developed and industry-leading RTK high-precision positioning algorithm, which enables high-precision positioning with an accuracy of less than 1 meter on OPPO mobile phones, and the technology will be commercially available in 2021.
RTK, known as “real-time kinematic”, is a technology based on carrier phase observation volume, through real-time processing of observation data between measurement stations, to remove errors in a differential way, so as to achieve more accurate positioning.
In the past, this technology was mainly used in the field of surveying and mapping, where the mapping equipment was large and the measurement operation was demanding.
OPPO has carried out a lot of tuning work in combination with mobile phone usage scenarios and antenna configurations, adding accelerometer, gyroscope and other mobile phone sensor information on the basis of the navigation chip, and through the self-developed high-precision positioning algorithm to comprehensively determine the phone’s position and eliminate interference to obtain more accurate results.
Not only that, in order to make the technology better on the ground, OPPO in the technology pre-research stage that close cooperation with China Mobile.
At the same time OPPO has joined China Mobile “5G Precision Positioning Alliance”, the future will be based on China Mobile’s satellite navigation ground-based augmentation system being deployed nationwide, using OPPO RTK high-precision positioning algorithm, and industry partners to promote the construction of high-precision positioning technology ecology.
Liu Chang, Vice President of OPPO and President of Research Institute, said: With 5G becoming a reality, all kinds of intelligent application scenarios have put forward higher demands on the accuracy of indoor and outdoor positioning.
From the perspective of user experience, OPPO applies RTK technology to smartphones through its self-developed algorithm, which will significantly improve the positioning accuracy of mobile phones. For this technology, we have also launched a long-term and in-depth cooperation with China Mobile, hoping to bring the new experience to users as soon as possible.
