GNS Ambiguity Resolution Techniques
Original language description
For a high accuracy attitude determination using GNS (GPS etc.), it is required to determine the integer cycle ambiguities for the GPS double difference phase measurements. Using the non-dedicated GPS receivers incorporated within the attitude system (capable of both code and carrier phase measurements), the carrier phase measurements can be made to the level of 1-10 mm, but only the fractional portion of the phase cycle can be measured. The integer number of whole cycles separating the receiver and satellite cannot be measured by the receiver and must be determined independently. These ambiguities must be estimated at system start-up and whenever phase lock is lost. An attitude system intended for kinematic applications is required to have an ambiguity resolution process that allows the determination of the ambiguities nearly instantaneously and with the antenna array in motion.

Czech description
Pro určení polohy pomocí diferenčního fázového měření je nutné určit ambiguity. Vyřešením tohoto problému je možné dostat se na určení polohy s přesností v řádu mm. Tento článek popisuje metody odhadu ambiguit a zároveň metody vyhodnocení jejich efektivity.
