Question

(i) F A users position solution with a 1 - degree error in his longitude measurement translates to the same distance at any latitude in the world. (ii) T The GPS week commences on midnight between Saturday evening and Sunday morning. (iii) T GPS consists of three main segments: Space Segment, Control Segment, an User Segment. (iv) F The GPS receivers clock offset from GPS system time can be corrected by implementing the clock correction algorithm contained in the 50 bits per second navigation data. (v) T The GPS satellite constellation is comprised of 6 orbital planes. (vi) T Each orbital plane is inclined at 55 degrees relative to the equatorial plane. (vii) F GPS Time of Week 455,000 seconds occurs during Wednesday of a GPS week. (viii) F One coarse/acquisition pseudorandom noise chip has a wavelength of 10 seconds. (ix) F The GPS L2 frequency of 1575.42 MHz has a wavelength of 7.5 inches. (x) F GPS satellites have a period 11 hours and 57 minutes.
