"1. It takes 7 minutes for a GPS receiver to receive all the data frames in the navigation message." Incorrect
The NAV message is sent in 25/30 second data frames, therefore, sending the entire message takes a total of 12.5 minutes.

"2. The almanac contains only the orbital data of the specific satellite." Incorrect
The almanac consists of coarse orbit and status information for each satellite in the constellation, at any particular time.

"3. The clock correction parameters are data for correction of the satellite clock." Correct

The GPS satellites carry on-board atomic clocks of rubidium and cesium, which have accuracies on the order of 10^-9 and 5 x 10^-13 seconds, respectively. Despite the high stability of the clocks, differences in synchronization still exist between the time transmitted by the satellite and the GPS time. Therefore, it is necessary to provide correction of the satellite clock error.

"4. The UTC parameters are factors determining the difference between GMT and UTC." Incorrect
UTC parameters is the correction the receiver needs to turn the GPS time which it works on into UTC time so it can display to the pilot. The difference is currently 18 sec.
