Depending on operating conditions, use of high Noise payloads can sometimes have an effect on GPS satellite acquisition times due to interference with the onboard GPS, especially in semi-occluded sky conditions. This improved GPS shield replaces the standard Copper shield with a shield constructed of high-performance emir absorbing polymer tuned specifically to the frequencies that GPS operates at. Less Noise on the GPS allows for quicker satellite acquisition times and more stable GPS performance in semi-occluded sky conditions. Improved performance against high noise Payloads Directly replaces standard Copper shield with an emir absorbing Polymer shield Quicker satellite acquisition times This listing is for a pack of 5 shields
