Systems and methods are provided for publishing immutable references to geospatial data. In embodiments, a method includes identifying geospatial data of a data provider, wherein the geospatial data is associated with a grid element of a discrete global grid (DGG); generating, in a grid element data store, an immutable reference in time to the geospatial data, the immutable reference including a pointer to a unique label of the grid element of the DGG and a storage location of the geospatial data; receiving a data request from a user, the data request including location information identifying the grid element; and providing a response to the user including the storage location of the geospatial data associated with the grid element to enable access of the geospatial data by the user, wherein the immutable reference provides a guarantee that the geospatial data is originating from the data provider.

Secure datastore of searchable heterogenous geospatial data

Disclosed embodiments provide systems and methods for implementing enhanced geo-restricted data management in satellite constellation datacenters. A disclosed system and methods implement a satellite constellation datacenter of multiple LEO satellites that enables real-time satellite communications using lasers and secure data storage in the satellite constellation datacenter to protect critical data from unauthorized access and supports secure data transfer between the LEO satellites using laser based data transfer. To enable secure storage of geo-location restricted data in a LEO satellite, the LEO satellite constellation datacenter defines a geo-location cone and requires that the geo-location restricted data be stored within the geo-location cone. LEO satellites within the defined geo-location cone store the geo-location restricted data and securely transfer the geo-location restricted data from one satellite to another satellite within the defined geo-location cone.

Geo-restricted data management in satellite constellation datacenters

A system includes a memory having instructions therein and at least one processor in communication with the memory. The at least one processor is configured to execute the instructions to communicate, into a user device, a deep neural network comprising a predictive audio spectral mask. The at least one processor is also configured to execute the instructions to: generate data corresponding to ambient sound via a multi-microphone device; separate amplitude data and/or phase data from the data via the deep neural network comprising the predictive audio spectral mask; and determine, via the user device and based on the amplitude data and/or phase data, a location of origin of target speech relative to the user device. The at least one processor is configured to execute the instructions to display, via the user device, the location of origin of the target speech relative to the user device.

Audio-spectral-masking-deep-neural-network crowd search

Isolating and amplifying a conversation between selected participants is provided. A plurality of spectral masks is received. Each spectral mask in the plurality corresponds to a respective participant in a selected group of participants included in a conversation. A composite spectral mask is generated by additive superposition of the plurality of spectral masks. The composite spectral mask is applied to sound captured by a microphone to filter out sounds that do not match the composite spectral mask and amplifying remaining sounds that match the composite spectral mask.
