NI 9467 Operating Instructions and Specifications
Contents
1. Antenna Installation Caution National Instruments recommends using a lightning arrester in line with the GPS antenna installation to protect the NI 9467 and the C Series system from possible damage and operators from injury in the event of lightning The embedded GPS receiver in the NI 9467 requires signals from several satellites to compute accurate timing and location The NI 9467 Operating Instructions and Specifications 8 ni com more satellites available to the receiver the more accurately it can determine time and location Therefore the antenna location should be such that it receives signals from the greatest number of satellites possible As the number of satellites visible to the antenna decreases the synchronization performance may also decrease Choose the antenna location so that the antenna has a clear view of the sky There is no strict definition for a clear view of the sky but a suitable guideline is that the GPS antenna should have a straight line of sight to the sky in all directions 360 down to an imaginary line making a 30 angle with the ground Locations far from trees and tall buildings that could block or reflect GPS satellite signals are best Maximum Cable Length Maximum cable length depends on the GPS antenna gain and the cable s loss per unit of distance National Instruments recommends a GPS signal strength of between 135 dBm and 120 dBm at the NI 9467 SMA input GPS signal strength on t2.
