A verified authentication device has a navigation receiver, a processor, and a verification device. Navigation signals are transmitted from a Global Navigation Satellite System (GNSS). The processor authenticates the navigation signals and determines position coordinates of the navigation receiver. The verified authentication device receives input from a user of the verified authentication device. The verified authentication device provides reliability of the position coordinates based on the input from the user.

Verifiable authentication services based on global navigation satellite system (GNSS) signals and personal or computer data

A method of extracting pseudorange information using a cellular device. A Global Navigation Satellite System (GNSS) chipset which is physically remote from a cellular device is accessed which provides raw GNSS observables information based upon signals received from a circularly polarized GNSS antenna. The raw GNSS observables information is wirelessly transmitted from the GNSS chipset to the cellular device. The raw GNSS observables information is extracted by a processor of the cellular device. The raw GNSS observables information, in addition to GNSS corrections from at least one correction source, is used by the processor to determine a position of the circularly polarized GNSS antenna.

GNSS receiver positioning system

A system for reporting incidents. A receiver for receiving cellular based communication corresponding to an incident, wherein the cellular based communication comprises an image. An incident location determiner for automatically determining a location of the incident based on the image of the cellular based communication. An incident report generator for generating a report of the incident, the report including the location of the incident.

Incident reporting

A method and system for variable data rate transmission in a real-time kinematic (RTK) positioning system. An RTK positioning system having a reference station and a rover utilizes wireless communications for data transfer. The data transmission rate between the reference station and the rover is dynamically controlled by a programmable transmission controller. The transmission rate is determined on the basis of specific parameters. Parameters that may be used to determine the data transmission rate include rover demand, required rover accuracy, satellite positioning system (SATPS) events, the required data for ambiguities, and the type and content of the data transmitted.

Method and system for variable data rate transmission in RTK GPS survey system

A survey system and method for determining the best source of position data for a particular application. The system includes both a satellite positioning system (SATPS) and a non-SATPS unit for obtaining position data. The SATPS unit includes a SATPS antenna and a SATPS receiver for receiving signals from satellites of the SATPS and a radio for coupling the received signals to the rover unit. Data is collected using both the SATPS and non-SATPS methods to obtain a master data set. Data is selected and/or combined from the master data set to produce the data subset required for position determination. The basic SATPS method may also be augmented by the use of one or more reference stations at known locations.
