Publication number: 20230284047Abstract: The described features generally relate to determining dynamic signal quality criteria for an installation of satellite terminals for communications in a satellite communications system. In particular, the signal quality criteria for an installation may be based on an identified position of the satellite terminal to be installed, and in some examples based on the positions and signal characteristics of neighboring satellite terminals that have already been installed. In some examples, a signal quality map may be generated for a service beam coverage area, based on predetermined transmission characteristics and/or measured transmissions from a number of satellite terminals served by a communications satellite. The generated signal quality map may then be used to determine a signal quality threshold for the installation of a satellite terminal being installed for communications in a satellite communications system.Type: ApplicationFiled: December 27, 2022Publication date: September 7, 2023Inventors: Kenneth V. Buer, Clifford K. Burdick, Ian A. Cleary, Ramanamurthy V. Darapu, David H. Irvine, Philip A. Lampe

Patent number: 11699838Abstract: Determining movement for alignment of a satellite antenna using accelerometer data and gyroscope data of the satellite antenna. Described techniques include receiving accelerometer data for a first time period from an accelerometer mounted on the antenna and analyzing the accelerometer data to determine a movement time window for a movement event of the antenna. The techniques may include receiving gyroscope data for the first time period from a gyroscope mounted on the antenna and analyzing the gyroscope data during the movement time window to determine an amount of movement of the antenna due to the movement event.Type: GrantFiled: February 28, 2022Date of Patent: July 11, 2023Assignee: Viasat Inc.Inventors: Clifford K. Burdick, Kurt A. Zimmerman, Kevin House, David H. Irvine

Publication number: 20220231757Abstract: The described features generally relate to receiving one or more positioning signals at a satellite terminal during installation of the satellite terminal at a customer premises, and providing position-based access to a satellite communications system based on a satellite terminal installation position determined from the received positioning signals. The determined installation position of the satellite terminal may then be employed for various network access techniques, such as providing access to the satellite communications system, providing position-based content, or restricting content via the satellite communications system based on the determined installation position.Type: ApplicationFiled: April 11, 2022Publication date: July 21, 2022Inventors: Kenneth V.

Patent number: 10763579Abstract: Systems and methods for aligning a satellite antenna mounted on a mobile platform to the platform. At each of several arbitrary orientations, a first directional vector is determined from the antenna to a satellite. For each orientation, an alias transformation is performed to transform the first vector having coordinates defined with respect to a first reference frame to a second vector having coordinates defined with respect to a second reference frame. A third vector is determined based on the orientation of the antenna after peaking the antenna. A rotation matrix is derived from the collection of second and third vectors. An estimate of the rotational offset of the satellite antenna with respect to the platform is determined based on the rotation matrix. The rotational offset is applied to the attitude of the platform to accurately point the antenna to the satellite.Type: GrantFiled: April 23, 2019Date of Patent: September 1, 2020Assignee: Viasat, Inc.Inventors: Brian T.
