The investigation of the transmitted signals started immediately after the launch of Compass -M1 on 14 April 2007. Soon after in June 2007, engineers at CNES reported the spectrum and structure of the signals. A month later, researchers from Stanford University reported the complete decoding of the "I" signals components. The knowledge of the codes allowed a group of engineers at Septentrio to build the COMPASS receiver and report tracking and multipath characteristics of the "I" signals on E2 and E5B.
Who built the COMPASS receiver?
a group of engineers at Septentrio

Although the city lost the status of state capital to Columbia in 1786, Charleston became even more prosperous in the plantation-dominated economy of the post-Revolutionary years. The invention of the cotton gin in 1793 revolutionized the processing of this crop, making short-staple cotton profitable. It was more easily grown in the upland areas, and cotton quickly became South Carolina's major export commodity. The Piedmont region was developed into cotton plantations, to which the sea islands and Lowcountry were already devoted. Slaves were also the primary labor force within the city, working as domestics, artisans, market workers, and laborers.
In what year was the cotton gin invented?
1793

In the light of Mother F. A. Forbes research and reference to Pope Saint Gregory's writings, it would appear that Athanasius was constrained to be Bishop: She writes that when the Patriarch Alexander was on his death-bed he called Athanasius, who fled fearing he would be constrained to be made Bishop. "When the Bishops of the Church assembled to elect their new Patriarch, the whole Catholic population surrounded the church, holding up their hands to Heaven and crying; "Give us Athanasius!" The Bishops had nothing better. Athanasius was thus elected, as Gregory tells us..." (Pope Gregory I, would have full access to the Vatican Archives).
What did he do when he thought he might be made Bishop?
