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.

Preserving positioning accuracy with age of data

A method includes receiving electromagnetic signals containing pulses. The method also includes converting the pulses contained in the electromagnetic signals into an electrical signal that identifies at least some of leading or trailing edges of the pulses. The method further includes repeatedly (i) accumulating the electrical signal to generate a voltage using an integrating circuit and (ii) resetting the integrating circuit in response to the voltage of the integrating circuit meeting or exceeding a threshold voltage. In addition, the method includes providing a count value identifying a number of times that the voltage of the integrating circuit meets or exceeds the threshold voltage. Each time the voltage of the integrating circuit meets or exceeds the threshold voltage is representative of a specific number of pulses received in the electromagnetic signals.

Capacitive batch counting to support one-way time-of-flight or other operations

A method includes transmitting a first electromagnetic signal from a first node to a second node and receiving a second electromagnetic signal from the second node at the first node. The method also includes repeating the transmission of the first electromagnetic signal and the reception of the second electromagnetic signal multiple times. The method further includes identifying, based on the repeated transmissions and receptions, a time-of-flight associated with a travel time for one of the electromagnetic signals to travel between the first and second nodes. The time-of-flight is indicative of a distance between the nodes.

Localization using repeated transmissions of electromagnetic signals for mobile ad hoc networks

A method includes communicating first and second signals between a first node and a second node, where the first signal includes a sonic signal and the second signal includes an electromagnetic signal. The method also includes using the electromagnetic signal to one of start or stop a timer and using the sonic signal to another of stop or start the timer. The method further includes identifying a one-way time-of-flight associated with the sonic signal traveling between the first and second nodes using the timer. The one-way time-of-flight associated with the sonic signal is indicative of a distance between the nodes.

A training system for a jumper on a jump path over a crossbar predicts the jumper's flight path and cues the jumper if the flight path is too close to the crossbar or to take action if the jumper is predicted to strike the crossbar. The system includes a sensor viewing the jumper from a direction paralleling the crossbar and producing data points representative of the lowest edge of the jumper in the vicinity of the crossbar. A computer receiving the data points is programmed to determine therefrom the jumper's flight path, the jumper's forward speed, the location of a jumper's lower legs relative to the crossbar, an expected impact time of the lower legs with the crossbar, and a cuing time. A cuing device, such as a horn, cues the jumper to raise the lower legs so as to not impact the crossbar.

Covert acoustic communications (CAC) through solid propagation channels that connect node pairs is achieved by encoding signals using spread spectrum coding techniques that position the encoded signal at a center frequency fwithin a narrow frequency bandwidth BWin which the amplitude of the channel response H(f) between each node pair is relatively high. The channel response H(f), bandwidth BWand center frequency f, and accordingly the signal data rate will adapt for each node pair and possibly each side of the node pair. A pre-distortion filter 1/H(f) pre-distorts the encoded signal over bandwidth BWto compensate for material and modal dispersion and multipath between the node pair. This technique avoids the problems associated with frequency dependent attenuation of the continuous solid path and allows for simultaneous transmission and reception of signals among the multiple node pairs.

A method includes transmitting a first electromagnetic signal from a first node to a second node through free space. The method also includes transmitting a second electromagnetic signal from the first node to the second node through a communication link, where the communication link physically couples the first and second nodes. The method further includes identifying a distance between the first and second nodes based on a time-difference-of-arrival between reception of the first electromagnetic signal at the second node and reception of the second electromagnetic signal at the second node.

The object detection system transmits the map definition and series of overlays to the collision processing circuit so as to determine a probability of a collision.
