Latest Patents

Isaacs' latest patents include innovative systems and methods for GNSS SNR probabilistic localization and 3-D mapping. These embodiments encompass various systems, methods, devices, and software for GNSS simultaneous localization and mapping (SLAM). The disclosed techniques illustrate that SLAM can be effectively performed using only GNSS SNR and geo-location data. A principled Bayesian approach is utilized, where a 3-D environment map is decomposed into a grid of binary-state cells, known as an occupancy grid. The receiver locations are approximated by sets of particles, and likelihoods of blockage are associated with every receiver-to-satellite beam. Loopy Belief Propagation is employed to estimate the probabilities of each cell being occupied or empty, along with the probability of the particles for each receiver location.

Another notable patent is the system and method for localization and tracking using GNSS location estimates, satellite SNR data, and 3D maps. This method determines the location of a user device by receiving GNSS fix data that represents the calculated position of the device. It also incorporates signal strength data associated with each satellite and map information regarding the environment surrounding the user device. The GNSS fix data and signal strength data are processed through a non-linear filter, which fuses the data to generate an updated position estimate of the user device.
