Abstract
A low profile mobile in-motion antenna and transmit/receive terminal system for two-way “VSAT” type satellite communication using FSS service, preferably in Ku band, supporting at the same time TV signal reception from the same satellite or a separate DBS satellite located at the same or nearby geo-stationary orbital position.
Claims22
A mobile in-motion terminal system for concurrently communicating by at least one antenna with (1) one satellite disposed at a geostationary orbital location and providing both TV broadcast and two-way data communications and/or (2) at least two satellites located at substantially the same geo-stationary orbital position, with one satellite providing TV broadcast and another satellite providing two-way data communications, said terminal system comprising:
- a transmit/receive system coupled to said antenna and comprising a transmitter and receiver operative to provide two-way type data communication using a first frequency band with said one satellite, and a receive system coupled to said antenna and comprising a receiver operative to receive TV signals from said same or other satellite;
- wherein the antenna is adapted for integration into a roof of a mobile vehicle and adjustable in both azimuth and elevation or the antenna is mountable on a mobile vehicle and is adjustable in at least an azimuth wherein the antenna comprises at least one transmit antenna array or receive antenna array.
A method of providing in-motion mobile concurrent communication for direct broadcast satellite television reception and two-way data communication, comprising:
- receiving at an antenna coupled to a mobile terminal mounted on a vehicle in motion at least one of direct broadcast television signals and data communication signals transmitted by satellite from substantially the same orbital location in geostationary orbit;
- identifying at said mobile terminal said orbital location;
- adjusting an antenna in at least one of azimuth and elevation so that it is pointed to said orbital location while said vehicle is in motion;
- and transmitting data to said orbital location from said antenna while said vehicle is in motion.
