Example embodiments are directed to systems and methods for generating and providing elevation-aware hotspots. In example embodiments, a network system detects an initiation of a request for a transportation service at a client device of a user and receives an indication of a location of the client device and corresponding signal strengths associated with the client device. The network system then determines a telematics vector based on the signal strengths associated with the client device. Based on the location of the client device and the telematics vector associated with the client device, the network system identifies one or more top ranked elevation-aware hotspots. A pickup point recommendation is then presented, by the network system on a user interface on the client device of the user, whereby the pickup point recommendation includes the one or more top ranked elevation-aware hotspots.

Elevation-aware hotspot generation system

A network system, such as a transport management system, infers movement and a location of a vehicle associated with a transportation service using sensor data from a provider client device and a wireless device mounted in a fixed position in the vehicle. Before or during a transportation service, the provider client device transmits sensor data to the network system for use in detecting the occurrence of one or more specified events, such as a sudden deceleration or a harsh turn. The network system fuses the received sensor data to infer the movement of the vehicle along forward, lateral, and vertical axes and implements an event detector by analyzing movement of the vehicle in the forward direction. Fused sensor data received from the wireless device is used to validate the detected movement and to determine a position of the vehicle.

Inferring vehicle location and movement using sensor data fusion

Aspects of the disclosure relate to initializing an inertial navigation system (INS) of a mobile device. Accelerometer bias of a plurality of accelerometers of the mobile device, and gyroscope bias of a plurality of gyroscopes of the mobile device, are determined. A first spatial relationship between a first frame of reference of the mobile device and a second frame of reference of a vehicle transporting the mobile device is determined. A second spatial relationship between the first frame of reference and a third frame of reference of a surface beneath the vehicle is determined. Each of the frames of reference are determined based on output of at least two of the GNSS receiver, the plurality of accelerometers, or the plurality of gyroscopes. The INS is provided with the accelerometer bias, the gyroscope bias, the first spatial relationship, and the second spatial relationship to initialize the INS.

Correction of motion sensor and global navigation satellite system data of a mobile device in a vehicle

In some embodiments, Satellite Positioning System (SPS) time information associated with at least one SPS may be maintained at a UE, which may also receive time information from a Wireless Wide Area Network (WWAN). In some embodiments, the UE may determine a corrected SPS time information for a first time based, in part, on the received WWAN time information, where the corrected SPS time information corrects the SPS time information associated with the at least one SPS maintained at the UE. The UE may initiate transmission of SPS timing assistance information to an associated device over a Wireless Personal Area Network (WPAN), wherein the SPS timing assistance information comprises the corrected SPS time information for the first time.
