Will the Spearville-Knoll-Axtell 345-kV line adversely affect the operation of my GPS?
Normal reception of GPS signals will be unaffected by the operation of the Spearville-Knoll-Axtell 345-kV line. GPS equipment operates in the Ultra High Frequency (UHF) part of the electromagnetic spectrum. Normal operation of the Spearville-Knoll-Axtell 345-kV line will result in no significant energy in this part of the radio spectrum. However, some GPS equipment itself may not be shielded adequately for its electronics to always function properly in the electrical environment directly under the line. This is rare, and no action is warranted in anticipation of a problem. If you have some evidence that GPS-guided precision agriculture equipment is not working properly under a transmission line, please contact ITC Great Plains for advice.
