Abstract: A method for estimating a boundary for a future location of a moving object includes: receiving location information about two previous locations of the moving object represented by a first and a second elliptical error probabilities (EEPs); representing each of the EEPs as a conic section via an implicit quadratic equation; defining four tangent lines from the implicit quadratic equation, each tangent line being tangent to both of the EEPs; determining two transverse tangent lines from the four tangent lines; forming a cone in a direction from the first EEP to the second EEP from the two transverse tangent lines; and estimating the boundary of the future location of the moving object as a first side of the cone formed by a first transverse tangent line and a second side of the cone formed by a second transverse tangent line, of the two transverse tangent lines.

Abstract: A system generates a tailored contact plan using a set of contact commands that represent a contact plan of communication opportunities between nodes in a network, an identification of restricted nodes in the network, and an identification of a target node. The system processes the records in the contact plan by writing a record to the tailored contact plan when the record is not a contact command; or writing the record to the tailored contact plan when the record includes the contact command, and a source node in the record is not a restricted node or the source node in the record is the target node; or writing the record to the tailored contact plan when the record includes the contact command and the destination node in the record is the target node. The target node uses the tailored contact plan to route data through the network.

Abstract: A method for generating contact graphs for delay/disruption tolerant networking for a constellation of network nodes (e.g., satellites in low earth orbit, terrestrial sensors, and ground stations). A contact graph indicates the availability and data rates for communications links between spacecraft and ground stations. The links may be intermittent due to orbital dynamics and the earth's rotation, and may be line-of-sight or relayed. The method predicts the future locations of satellite nodes in the Earth Centered inertial reference frame, and converts the locations of terrestrial nodes by converting their coordinates from the Earth Centered Earth Fixed reference frame. The method also determines whether line-of-sight links are possible, and estimates the closing velocity between network nodes to estimate signal Doppler shift. Contact graph routing determines the links used to most effectively move data over the network. Output data files may be directly used by Interplanetary Overlay Network administration software.

Abstract: A system can identify, from a point cloud representing a scene, one or more scene elements, each with an element type, such as a building, a tree, or a parking lot. Each element type can have at least one associated electromagnetic propagation parameter, such as reflectivity, transmittivity, or absorptivity. A raytracing model can simulate electromagnetic radiation radiating from at least one electromagnetic radiation source positioned in the scene. The radiation can interact with a surface mesh representation of the scene elements. The system can calculate, from the simulation, a spatially-varying radiation level within the scene, and can augment the point cloud with data corresponding to the radiation level. The system can optionally display a visualization of the point cloud augmented with the radiation level data and can optionally display an indication of volumes in which the calculated radiation level falls below a threshold radiation level.

Abstract: Embodiments regard improved satellite position determination with age of measurement data. A method includes receiving measurement data from a satellite, in a first iteration, increasing a dimensionality of the measurement data to a specified number of dimensions resulting in N-dimensional input data, performing dynamic mode decomposition on the N-dimensional measurement data resulting in a Koopman operator and modes of the N-dimensional measurement data, adaptive filtering a time domain residue resulting in a filtered residue, and updating, based on the filtered residue and a time domain deterministic component of the N-dimensional measurement data, a state vector of an object associated with the satellite measurement data.
