Abstract: A method of receiving two chip-by-chip multiplexed CSK signals (e.g., GNSS signals) and searching for a non-CSK signal with optimal performance at a given digit capacity of a sampling memory resided in parallel correlators. For CSK signals Prompt, Early and Late results for each of possible code shift are calculated as different sums of four punctured convolutions. Depending on configuration, the method allows to receive both multiplexed CSK signals with lesser quality or one of the CSK signals with better quality. The method can be implemented as an apparatus with four punctured correlators, a set of multipliers by 1 or 2N, another set of multipliers by 1 or 0, summers of four input to one result, a RAM, searchers of maximum, and conditional commutators.

Abstract: An apparatus includes a first modulator (418) configured to modulate a radio frequency (RF) input signal (402) onto a first optical signal and a second modulator (430) configured to modulate a local oscillator (LO) signal (404) onto a second optical signal. The apparatus also includes a photonic integrated circuit (304, 602) having an optical demodulator configured to generate, using the modulated optical signals, I and Q signals (444a-444b) representing a demodulated version of the RF input signal. The optical demodulator may include an optical filter bank (422) having multiple optical filters (424, 426), where different optical filters are configured to pass different frequencies or frequency ranges. The optical filters may include at least one narrowband optical filter (424) and/or one or more tunable optical filters (426). The narrowband optical filter(s) may be configured to isolate global navigation satellite system-related signals. The tunable optical filter(s) may be configured to isolate signals over a frequency range of about 900 MHz to about 12 GHz.

Abstract: Various embodiments of the present technology generally relate to multi-frequency satellite navigation receiver technology. More specifically, some embodiments relate to an inter-frequency signal aiding technique for multi-frequency signal tracking in a multi-frequency receiver. The present technology enables a satellite navigation receiver (such as GPS) to continue operation, or to have improved performance, in environments where signals on one or more frequency bands experience fading. Some embodiment can estimate parameters of signal channels that experience fading based on measurements obtained from all or other less compromised frequency bands in linear operation by the receiver. Some embodiments can optimally estimate carrier parameters of navigation signals with consideration of relative measurement qualities. These parameters are used to construct the local reference signals, maintain lock on the fading signals, and obtain accurate positioning solutions and remote sensing observations.

Abstract: Described herein is a method for improving the reception of a satellite navigation message divided in several pages and transmitted by one or several satellites. A satellite navigation message M of k pages is encoded in n pages, and any k retrieved pages from any satellite enables decoding of the original satellite navigation message M . An implementation of the method uses parallel block encoding for a binary erasure channel with high parity and zero overhead, where symbols at a fixed position of all pages are encoded in parallel into shorter codes. This method achieves full page interchangeability in the message transmission, optimizes message reception and reduces decoding cost.

Abstract: Methods and systems are disclosed for processing satellite positioning system (SPS) signals at a mobile device. In an embodiment, SPS signals may be acquired at multiple instances over a first duration while the mobile device is camped on one or more signals transmitted by a first access device (202). The mobile device may then determine a second duration of time to acquire a subsequent SPS signal based, at least in part, on the acquired SPS signals, representations of system time in signals received from the first access device contemporaneously with acquisition of the SPS signals and an indication of stationarity of the mobile device during the first duration (204).
