Figure 8: Modernization Milestone

FIGURE 8: The full spectrum captured by the 18-meter parabolic antenna at 5:46 a.m. PDT at Table Mountain, CO. Because the facility does not use a bandpass filter, all GPS bands  (from left to right, L5, L2, L3, and L1) are shown. The GPS signal spectrum from this antenna is boosted higher above the noise floor than the Stanford SGMS antenna, due to the higher antenna gain provided by the larger antenna parabolic reflection area.
