  • Patent number: 10348347
    Abstract: An apparatus for monitoring radio frequency (RF) signals is disclosed. The apparatus includes an RF splitter, a set of track-and-hold circuits, a set of analog-to-digital circuits (ADC) and a frequency tracking module. The RF splitter splits a set of incoming RF signals into multiple RF signal paths. Each of the track-and-hold circuits, which is clocked at a different frequency than others, samples the incoming RF signals from a respective one of the RF signal paths. Each of the ADCs receives the sampled data from a respective one of the track-and-hold circuits. Each of the ADCs is also clocked at same frequency as a corresponding one of the track-and-hold circuits. The frequency tracking module determines a frequency of the incoming RF signals.

  • Patent number: 10005567
    Abstract: A method for stationing a satellite comprises a transfer phase, during which the satellite moves on an elliptical geosynchronous orbit, the orbit being deformed progressively by application of a thrust by electrical or hybrid electrical-chemical propulsion to bring it closer to a geostationary orbit. The transfer step comprises a substep during which, during a plurality of revolutions of the satellite, the thrust is stopped for a fraction of orbital period and tests of a telecommunications payload of the satellite are performed in the absence of thrust.

  • Patent number: 9998207
    Abstract: Systems, methods, and software described herein provide enhancements for deploying communication networks in clusters of satellite devices. In one example, a first subset of satellite devices is configured to orbit in a first orbital layer, and a second subset of satellite devices is configured to orbit in a second orbital layer. A communication network is formed among the satellite devices and is configured to selectively exchange communications among the first orbital layer and the second orbital layer based at least in part on an operational status of the communication network.

  • Patent number: 9998206
    Abstract: A plurality of spacecraft may be dispersed into a ring constellation or structure. Data may be wirelessly relayed between spacecraft similar to data flowing in a ring network. The ring structure minimizes inter-spacecraft velocities and tracking angle motion to allow use of fixed high-gain radio frequency (RF) antennas or medium-divergence lasers for crosslinks. Data may flow between spacecraft to be downloaded by the next spacecraft that will be passing over a ground station. This reduces data latency when a single ground station is used, and significantly reduces data latency when more than one ground station is used.

  • Patent number: 9971037
    Abstract: Systems and methods are provided for monitoring carrier phase anomalies in a range finding system. A relative carrier phase between first and second antennas is predicted as a function of a relative position between the two antennas. A relative carrier phase between the first and second receivers is measured based upon at least one transmitted signal received at each of the first and second antennas. An anomaly detection metric is calculated as a difference between the measured relative carrier phase and the predicted relative carrier phase. It is then determined if an anomaly is present according to the anomaly detection metric.
