Cambridge Silicon Radio (CSR) today announced it is launching an Android software development kit (SDK) in 2015 that will allow developers to create apps with indoor positioning.

The firm, which was also behind the world's thinnest keyboard, said that its SiRFusion SDK, will enable developers to integrate new location-based capabilities and services into their apps, such as indoor location tagging and analytics for social networking applications, indoor navigation, lone worker efficiency and safety capabilities, as well as indoor asset tracking and targeted e-commerce services.

CSR is one of several companies working on indoor-mapping technologies, like rival Indoor Atlas in Finland. Traditional mapping technologies, such as global positioning satellite (GPS) systems, don’t work because they need a line-of-sight to fix a location.

To overcome this and track indoor location, CSR combines real-time wi-fi signals, satellite positioning information, pedestrian dead reckoning, and the company’s cloud-based CSR Positioning Center to calculate the indoor location.

The system automatically crowd-sources a venue’s indoor wi-fi signatures as consumers walk through the location, and it has also been architected to accommodate future proximity and location technologies such as bluetooth smart beacons, wi-fi round trip time (RTT), and indoor messaging system (IMES).

“Offering indoor positioning accurate enough to be useful has been a challenge that the industry has been trying to solve for many years,” said Anthony Murray, SVP of the Business Group at CSR.

“But with consumers coming to expect anytime-anywhere positioning wherever they are, our customers have continued to express a growing interest for accurate indoor positioning without the need for additional infrastructure. With our SiRFusion Software Development Kit, we have, for the first time, made indoor location a reality for developers who want to deliver innovative location-based products and services without proprietary infrastructure.”

It will be possible to integrate SiRFusion for Android into any app running on Android version 4.4 or later.
