Geostar also states that the satellites will be capable of supporting 43—DSS—MP/ML—90 hand—held user terminals and providing position deter— 44—DSS—MP/ML—90 mination by range measurements obtained through two 51—DSS—EXT—90 satellites and altitude information obtained from a 52—DSS—EXT—90 digitized terrain map or on—board altimeter. Finally.

Each of the dedicated RDSS satellites is to carry one inbound channel and one Geostar proposes to modify the license for its third dedi— outbound channel and will have a single 3.5° by 7° cated RDSS satellite —— Geostar 3 —— as authorized in coverage pattern that can be repointed while the satellite Geostar Corporation, Mimeo No. 6144 (released August 7. is in—orbit to serve user terminals either in the contiguous 1986). to conform the satellite—to—control cemer frequen— U.S. or in other points of the western hemisphere. The cies to the allocations made at the 1987 World Admin— following frequency bands are requested: istrative Radio Conference for Mobile Services (MobileWARC—87). Specifically. Geostar requests a shift in the assigned frequencies for this link from 5117—5183 MHz to 5150—5216 MHz. All other parameters of the 5 GHz satellite—to—control center link are to remain the same as authorized. In addition, Geostar requests an ex— tension of Geostar 3‘s construction completion milestone until October 1995 and its launch milestone until Decem— ber 1995.
