Abstract: A system and method for determining the roll rate and roll angle of a spinning platform, using the measured phase differences between the GPS satellite signals received on two or more antennas. The measured phase differences and the navigation solution from a GPS receiver are processed in a Kalman filter to obtain the desired information. Data from non-GPS measurement sources is optionally provided to update the navigation solution. Although of wide applicability, the invention is uniquely suited to the measurement of roll rates and roll angles of fast spinning platforms with small baselines, in which the antennas are separated from each other by distances that are a fraction of the GPS signal wavelength.

Abstract: A digital adaptive transversal filter includes an interface circuit for regulating and digitizing analog input signals, which comprise of multiple spread-spectrum signals, additive thermal noise and additive multiple narrowband interferers, to provide multi-bit digital input signals. A digital finite impulse response filter having a set of variable digital weight coefficients responds to the multi-bit digital input signals to generate digital output signals which contain a reduced amount of narrowband interference. A digital weight generator responds to the digital input and digital output signals for updating the digital weight coefficients, and a reset generator periodically resets the digital weight coefficients to zero initial values.In a preferred embodiment an 8-tap, 8-bit digital adaptive transversal filter operating at 22 MHz was implemented with discrete components and a processing gain of 30 dB was demonstrated.

Abstract: The GPS/GNSS receiver and method disclosed herein improves the GPS/GNSS receiver tracking sensitivity for detecting low signal-to-noise (SNR) GPS/GNSS signals through improved vector tracking, multibit correlation, improved extended range code-phase discrimination, and discrimination and navigation filter measurement via Probabilistic Data Association, individually or in combination. The solution is achieved without any external data aiding, such as from an inertial measurement unit, other wireless infrastructure source, or communication of GPS/GNSS satellite vehicle (SV) subframe data to the GPS/GNSS receiver over a data link.
