Ultra-sensitive GNSS receiver

Accurate and reliable deep indoors positioning enabled by cloud processing of GNSS and Wi-Fi signals. Overview location.io’s ultra-sensitive GNSS receiver is a hosted GNSS hybrid location service that uses cloud-based computing to determine a position from the GNSS, Wi-Fi or cellular signals collected by the device. This is accomplished by off-loading all the complex baseband processing to Rx Networks’ servers.

Client devices upload snapshots of raw GNSS signals along with a list of observed Wi-Fi access points or cell tower IDs. Location.io uses this information to calculate an accurate position by using an advanced Hybrid Positioning Engine (HPE) developed by Rx Networks. The HPE algorithms are flexible enough to accurately determine a position even in places that are challenging for GNSS such as indoors and dense urban environments.

The GNSS signals submitted by the client devices can typically be captured using a standard, low-cost RF front-end receiver. Alternatively, these signals can be captured via the onboard GNSS chip, if the device is so equipped, and relayed to location.io when the onboard chip determines it is unable to resolve a fix.

Sample Applications Static Indoor Positioning: Devices such as network infrastructure elements (access points, routers, small cells) are often located indoors. location.io introduces the ability for these devices to autonomously self-locate. By taking advantage of snapshots taken over a period of 24 hours, accurate indoor positioning can be achieved.

Tag & Locate: In Tag & Locate, snapshots of data are captured for later post-processing. Such applications can include geo-tagging of photographs, “track and trace” surveillance, and many other machine-to-machine (M2M) cases where logging of location is desired, but where the use of a dedicated GNSS chipset may prove too costly or require too much power to be effective.

Key Advantages This location.io service brings a new set of options for devices that require high availability and accurate positioning, but not necessarily in real-time, and where power or cost requirements may make a dedicated GNSS chipset impractical. As it evolves, the service will also bring new options to assist and supplement client-based GNSS receivers in severely challenging indoor signal conditions.

Cost & Power Efficiency: Not all devices require the fast time to fix, turn-by-turn navigation capability, or the power requirements of a full-blown GNSS chip. Using low-cost RF front end components and remote computing, location.io brings location capability to a broader range of devices.

Increased Sensitivity: The location.io ultra-sensitive GNSS receiver service is able to detect satellites with signals as low as -171 dBm. This increased sensitivity forms the cornerstone of deep indoor positioning, where GNSS signals are much weaker than outdoors.

Reliability: The service takes direct advantage of Rx Networks’ proven location.io platform which includes Real-time GNSS ephemeris and Wi-Fi & cell-ID positioning, solutions that assist the location needs of nearly a billion devices every day.
