169	Method and apparatus for efficient acquisition and tracking of satellites	US89895	1998-06-03	US6078286A	2000-06-20	Estevan Marcial Gonzales; Richard Alan Bienz

176	Eccentricity vector control with continuous or quasi-continuous maneuvers	US12930679	2011-01-13	US20120181386A1	2012-07-19	Vaclav Majer
A method of managing an eccentricity vector of a geosynchronous satellite orbit is provided. The method includes determining a desired target locus of an acquisition control of a satellite in a geosynchronous orbit, where the acquisition control ensures that an osculating trajectory of the satellite converges in mean to the target locus. Further, the method includes determining a solar pressure perturbation to the geosynchronous satellite orbit, honoring a hard eccentricity limit constraint of the satellite orbit using an ideal continuously controlled osculating trajectory, and controlling the eccentricity vector of the geosynchronous satellite orbit using a quasi-continuous control or a continuous control to mitigate or eliminate an annual solar pressure perturbation, where the quasi-continuous control or the continuous control maintains the satellite orbit within the hard limit osculating constraint and converges the eccentricity of the satellite orbit toward the ideal continuously controlled osculating trajectory of the geosynchronous satellite orbit.
177	Geosynchronous satellite communication system and method	US08657846	1996-05-31	US06226493B1	2001-05-01	Raymond Joseph Leopold; Dennis Paul Diekelman
A geosynchronous satellite system (10) uses crosslinks (30) between geosynchronous satellites (16) which travel along the same ground path (18) or are located within a common orbital slot (32) in order to increase traffic-carrying capacity and decrease signal delays. The geosynchronous satellites (16) can have substantial angles of inclination to provide high quality coverage within a wide range of latitudes (40, 42). In addition, the orbits can be elliptical, resulting in concentrated network capacity in either the northern or southern hemisphere. For co-positioned satellites (171-174), orbit perturbations are introduced in order to eliminate crosslink blockage caused by intervening satellites (172, 173). Methods for deploying and operating the geosynchronous satellite system enable network capacity to be modified (708) and routing (804), crosslinks (1008), and handoffs (908) to be controlled.
178	Method for automatically positioning a satellite dish antenna to satellites in a geosynchronous belt	US510991	1995-08-03	US5585804A	1996-12-17	Charles E. Rodeffer
A TVRO satellite dish antenna system mounted on the roof of a parked vehicle automatically determines its location and bearing relative to two geosynchronous satellites and then uses this information to accurately calculate the azimuths and elevations of any other geosynchronous satellites. A magnetic compass generates a magnetic bearing signal for the system. An estimated latitude and longitude for the vehicle are provide by the user based on the approximate geographic location of the vehicle. The estimated positions for a first geosynchronous satellite and a second geosynchronous satellite relative to the satellite dish antenna are calculated from this information. The satellite dish antenna is moved to an initial search position corresponding to the estimated position of the first satellite and then moved in a search pattern until the receiver detects a signal peak for a selected channel. The actual azimuth and elevation of the first satellite are calculated based on the position of the satellite dish antenna upon detecting the signal peak. These steps are repeated for the second satellite. Revised bearing, latitude, and longitude coordinates for the satellite dish antenna are calculated based on the actual azimuths and elevations of the first and second satellites. Finally, the azimuth and elevation of any remaining geosynchronous satellite can be calculated based on the revised bearing, latitude, and longitude coordinates for the satellite dish antenna.

The Medium Earth Orbit satellites are synchronized with the geosynchronous satellites to produce continuous links. A parameter to achieve the synchronization involves the positions of the Medium Earth Orbit satellite relays relative to the positions of the geosynchronous satellite relays. Another parameter to achieve synchronization involves the ratio between the orbital periods of the geosynchronous satellite relays relative to the orbital periods of the Medium Earth Orbit satellite relays. These parameters may be further adjusted to provide continuous links above the horizon of the earth. An additional satellite relay system is disclosed in which the high-orbit satellite need not be in geosynchronous orbit and in which a high-orbit satellite communicates over a continuous unbroken link with a low-orbit satellite. A further satellite relay system is disclosed in which more than two satellites are arranged at discrete orbit altitudes, again providing a continuous, unbroken daisy-chain link between satellites.
