SAILS engine not only uses WiFi APs/BTLE signal to do indoor positioning but also uses inertial sensors, such as accelerometer, compass, and gyro, to enhance the locating performance. This sensor fusion technology helps provide the smoothest and most accurate indoor positioning possible and improve accuracy from 10 meters to 2 meters. SAILS SDK includes accurate indoor locating, vector-typed indoor map, and path finding engine that can help developer to quickly deploy their indoor navigation app and guide customers to the right place. Our SDK also provides turn-by-turn navigation, the map will automatically rotate and follow user’s heading. Just like using GPS navigation outdoor, we put the same navigation experience indoor. Indoor map is not just a JPG file. It is the first impression to user. Now, developer can create their elegant indoor maps by themselves. SAILS uses vector-typed OSM indoor map, which can provides high quality and leveled map. User can smoothly pan, rotate, and zoom on the map. What is more amazing is that developer can decide what the indoor map would look like. By using map render editor, developer can quickly tune the render style to meet their requirement based on the same map. Upload the map and use BuildNGO to build fingerprint. For your information, you can easily build 1000 square meters fingerprint in just 15 minutes (You will need SAILS beacon to support positioning in iOS). When you build the PUBLIC project, it means other developers can directly access your indoor map and locating data and integrated into their APPs. Go ahead, we encourage you to open your in-location projects. You can freely to develop unlimited public projects. Let’s make indoor map better. You can also build the PRIVATE project. Only you can access indoor map and locating data in your APP, other developers cannot use your maps and locating data in their APP. Source.
