    Abstract: A hardware front-end for a software-defined GNSS receiver, which includes an antenna connected to a transmission line that is connected to a pair of separate circuits, one for receiving L1 signals and one for receiving L2 signals. Each circuit includes at least one bandpass filter, at least one LNA, and a single-chip GNSS receiver that receives analog RF signals and provides digitized I and Q signals. The pair of circuits differ in that a first one is designed to receive, filter, and amplify RF signals at the L1 frequency corresponding to the designed input frequency of the receiver and the second one is designed to receive, filter, and amplify RF signals at the L2 frequency, which is significantly different from the first frequency. The second circuit also includes a mixer to convert the L2 frequency to the L1 frequency, so that a similar receiver can be used in each circuit.

    Abstract: A radio frequency component receives and digitizes a first plurality of L1 Global Navigation Satellite System (GNSS) signals and a second plurality of L2C GNSS signals from a plurality of GNSS satellites. A software defined GNSS receiver operating on a processor of a cellular telephone separate from the radio frequency component derives carrier phase measurements from the first plurality of L1 GNSS signals and the second plurality of L2C GNSS signals during an epoch. A wireless message from a communication device located at a base location is received conveying pseudorange and carrier measurements derived from the first plurality of L1 GNSS signals from said plurality of GNSS satellites during the epoch. The cellular telephone determines a distance from the base location to said first location.

    Abstract: A method for contextual inference of user activity is disclosed. In one embodiment, an indication of the motion of a pole mounted sensing device comprising at least one motion sensor and a Global Navigation Satellite System (GNSS) receiver configured to at least generate raw GNSS observables is received from the at least one motion sensor.

    Abstract: A Global Navigation Satellite System (GNSS) chipset embedded within the cellular device is accessed. The GNSS chipset calculates raw pseudoranges. The raw pseudoranges are extracted from the GNSS chipset for processing elsewhere in the cellular device outside of the GNSS chipset. A position fix is determined based on the raw pseudoranges. Locally measured cellular device movement information is obtained from at least one sensor that is in a known physical relationship with the cellular device. The locally measured cellular device movement information is applied to the position fix.

    Abstract: A Global Navigation Satellite System (GNSS) chipset embedded within the cellular device is accessed. The GNSS chipset calculates raw observables that include raw pseudoranges and carrier phase information. The raw observables are extracted from the GNSS chipset for processing elsewhere in the cellular device outside of the GNSS chipset. Smoothed pseudoranges are provided by smoothing the raw pseudoranges based on the carrier phase information. The accessing, the extracting and the providing are performed by one or more hardware processors located in the cellular device and outside of the GNSS chipset.

    Abstract: A method for matching a region on an object of interest with a geolocation in a coordinate system is disclosed. In one embodiment, an image of a region on an object of interest is captured on an image capture device. The image is processed to detect a located feature using a feature detection algorithm. Further processing of the located feature is performed to derive a first feature descriptor using a feature descriptor extraction algorithm. The feature descriptor is stored in a memory. A database of feature descriptors having geolocation information associated with the feature descriptors is searched for a match to the first feature descriptor. The geolocation information is then made available for access.

    Abstract: External accessory data is collected at a mobile data collection platform provided by an external accessory of the mobile data collection platform. An image that includes a point of interest is captured by an image capturing device that is an integral part of the mobile data collection platform performs. Raw observables are obtained from an external GNSS raw observable provider that is separate from and outside of the mobile data collection platform. A position fix of the mobile data collection platform is determined based on the raw observable. Orientation information comprising a tilt angle and an azimuth angle is determined. External accessory data is received from an accessory that is external to the mobile data collection platform. The image, the position fix, the orientation information and the external accessory data are stored in hardware memory of the mobile data collection platform.
