Large Lock 'n Lock placed near the top of East Tiger Mountain, accessible on foot or bike year round. You should have excellent reception at this location.
What's the frequency, Kenith? For Geocachers, the answer could be 1575.42 MHz, the frequency of the L1 band carrier signal used to transmit position and navigation data to your GPS receiver. This signal carries a publicly accessible C/A "coarse-acquisition" pseudo-random code used for identification and timing, as well as an encrypted P, or "precision" code readable only by the military and other authorized users. It also carries satellite orbital, clock, and system status information, collectively called the navigation data. Wide Area Augmentation System, or WAAS, signals are also broadcast on the L1 frequency. WAAS uses a system of ground stations to monitor data received from the GPS satellites. The known position of the ground stations is used to calculate inaccuracies in the received GPS signal due to propagation delays in the ionosphere, as well as other, smaller effects. The resulting corrections are sent to special geostationary satellites for broadcast, allowing any WAAS-enabled GPS receiver to use this data for improved position accuracy.
