Iceload on GNSS Antennas • Surprisingly little is known about the effect of ice-load on a GNSS antenna • Snow does probably not have any significant effect • A 1.25 cm wet surface ice loading will (Ref: O’Keefe et al): • Reduce the SNR with 3 dB • Increase the rms position error of 1 m • Increase the number of cycle slips significantly Conclusion: Ice building up on the GNSS antenna doesn’t make any good!
