System and method for providing information to an operator of a vehicle
TL;DR: In this paper, an information system and method for providing information to an operator of a motor vehicle is presented. A destination location and a current position of the motor vehicle are established.
Patent
Practical method for upgrading existing GNSS user equipment with tightly integrated Nav-Com capability
Brent M. Ledvina,Clark E. Cohen,Todd E. Humphreys,William J. Bencze,Mark L. Psiaki,Bryan T. Galusha +5 more
TL;DR: In this paper, a method for adding an integrated Nav-Com capability to any Global Navigation Satellite System (GNSS) user equipment, such as GPS receivers, requires no hardware modifications to the existing user equipment.
Patent
Method for standard positioning service and precise positioning service cooperative operation
TL;DR: In this article, a system for standard positioning service and precise positioning service (PPS) cooperative operation is described, in which a PPS receiver is utilized to process the PPS data portion of a positioning signal and an SPS receiver was used to process SPS data portions of the positioning signal.

Patent
Method and system for using altitude information in a satellite positioning system
TL;DR: In this article, the altitude pseudomeasurement is used as a redundant measurement with fault detection and isolation techniques to determine whether at least one pseudorange has a faulty condition, and if the condition is a first state (not a fault state) the at least 1 pseudorange is used in the position solution algorithm.
Patent
Positioning and proximity warning method and system thereof for vehicle
TL;DR: A positioning and proximity warning method for vehicle includes the steps of outputting global positioning system signals to an integrated positioning/ground proximity warning system processor, measuring air pressure, and computing barometric measurements which is output to the integrated positioning and ground proximity warning processor; measuring time delay between transmission and reception a radio signal from a terrain surface and computing radio altitude measurement, and accessing a terrain database for obtaining current vehicle position and surrounding terrain height data, and receiving the position, velocity and time information or said pseudorange and delta range measurements of said global positioning systems, the inertial navigation solution
Patent
Vehicle positioning and data integrating method and system thereof
TL;DR: A vehicle positioning and data integrating process and system can substantially solve the problems encountered in avionics system integration, which employs integrated global positioning system/inertial measurement unit enhanced with altitude measurements to derive vehicle position, velocity, attitude, and body acceleration and rotation information as discussed by the authors.
Patent
Fault-tolerant inertial navigation system
TL;DR: In this paper, a Fault-Tolerant Inertial Navigation System (FTNS) consisting of at least two inertial navigation units is presented. But the two units are fully capable of performing navigational functions, and each of the units produces a set of independent navigational solutions at each of their respective outputs.
