Abstract: A system and method are disclosed for estimating the location of a satellite terminal. The terminal is selected from among a plurality of terminals, and one or more position estimates are generated for a satellite which provides service to the terminal. The position estimated can be generated, for example, by performing a first one or more iterative grid searches over a plurality of potential position estimates for the satellite. A location estimate is subsequently generated for the terminal by performing a second one or more iterative grid searches over a plurality of potential location estimates for the terminal.

Abstract: A system and method are disclosed for estimating the location of a satellite terminal. A plurality of gateways having known locations are identified. A plurality of reference terminals associated with the gateways are identified, wherein a reference round-trip time (RTT) for signals between each reference terminal and the gateways via the satellite is known. The RTT is used to estimate the satellite's position over a plurality of time instances. The location of a selected terminal associated with a selected gateway is estimated based, in part, on the estimated satellite positions and an RTT for signals between the selected terminal and the selected gateway.

Abstract: Systems and methods for real-time signal validation are disclosed. In an example embodiment, a subset of terminals in a peer group of satellite terminals is determined. Operational statistics of the satellite terminals in the subset of terminals is measured. Operational statistics of each of the satellite terminals in the subset of terminals is compared to a prior measurement of the same operational statistics. An offset between a current measurement of the operational statistics and the prior measurement of the same operational statistics is determined. An average offset of the current measurement of the operational statistics and the prior measurement of the same operational statistics is determined for the subset of terminals. The average offset for the subset of terminals is merged with a previously determined peer group operational statistic. A signal validation of a terminal is performed using an updated deviation value.

Abstract: Systems and methods for peer group diagnosis detection are disclosed. In an example embodiment, a beam profile including a plurality of satellite beam characteristics is determined. A peer group of satellite terminals is determined. Terminal profiles with terminal characteristics for the satellite terminals in the peer group are determined. A normalized baseline profile including normalized terminal characteristics for the peer group is determined. Measured operational statistics of the satellite terminals in the peer group are received and converted into normalized operation statistics using the terminal profiles and the normalized baseline profile. Normalized peer group operational statistics including a mean and a standard deviation of normalized operational statistics are determined. A normalized deviation of the normalized operational statistics is determined for each satellite terminal. The normalized deviations for each satellite terminal are compared to a threshold deviation.

Abstract: Terminal diagnosis self correction is disclosed. A service inquiry is received regarding a problem with a terminal from a user. Terminal statistics are obtained remotely from the terminal and stored in a site diagnosis log. An initial diagnosis is determined with a site diagnostic tool using the terminal statistics. The initial diagnosis is stored in the site diagnosis log. A technician is dispatched to repair the terminal. Terminal statistics are obtained locally at the terminal and stored in an onsite validation tool log. An onsite diagnosis is determined using an onsite validation tool and stored the onsite validation tool log. The initial and onsite diagnoses are compared. In response to a difference between the initial and onsite diagnoses, the remotely and locally obtained terminal statistics are compared. The site diagnostic tool is adjusted based on the initial diagnosis, the onsite diagnosis, and the remote and local terminal statistics.

A satellite terminal is diagnosed with a problem defined by the problem signature based on the determined diagnosis zone.
