For further information, refer to . The measurements are the source of much of the information in the IGS calibration file . Station operators or GPS equipment manufacturers planning to deploy new or uncalibrated antennas are invited to use this calibration service. Whenever possible, it is preferable to test multiple samples of the same model. There is no fee charged for the testing, but we do ask that the return shipping charges be paid by the sender. For further information, please contact me at the address below.
