Patent
Attitude determination method and system
TL;DR: In this paper, a method for use in vehicle attitude determination includes generating GPS attitude solutions for a vehicle using three or more antennas receiving GPS signals from two or more space vehicles and a processing unit of the system having the capability to generate GPS attitude computations for the vehicle using the 3 or more GPS antenna/receiver sets.
Patent
Differential gps ground station system
TL;DR: In this article, a differential satellite positioning system is configured to include a plurality of satellite positioning receivers in close proximity of one another for determining independent pseudo range values which are processed in accordance with a selected averaging scheme for determining highly reliable satellite differential corrections.
Patent
Attitude change kalman filter measurement apparatus and method
TL;DR: In this paper, a navigation system includes a Kalman filter to compensate for bias errors in inertial sensing elements, and an observed pitch, roll or heading change is input to the filter either from an aiding source or when the system is in a known condition.
Patent
GPS receiver RAIM with slaved precision clock
TL;DR: In this paper, a method and a system for providing a substituted timing signal for a missing satellite ephemeris in execution of a RAIM algorithm includes deriving a plurality of position, velocity, and time solutions from a GPS navigation system.
Journal ArticleDOI
Design and Flight Test of a Differential GPS/Inertial Navigation System for Approach/Landing Guidance
TL;DR: In this paper, a flight test program evaluating a differential GPS/inertial navigation system's utility as an approach/landing aid was conducted at NASA-Langley.
