Galileo E5b Rover Receiving E5a Corrections? No Problem!

Jean-Marie Sleewaegen and Wim De Wilde

Abstract:	With the large selection of signals available from today’s GNSS satellites, it becomes difficult to ensure that rovers get the corrections they need from the base station or the RTK network. For example, cases of Galileo E1&E5b rovers in an RTK network which is providing corrections for E1&E5a are not uncommon. In such situation, rovers used to have no other choice but to revert to a loweraccuracy single-frequency positioning mode. The paper presents a patent-pending technique aimed at addressing the problem. It is shown that it is often possible to re-create the missing corrections at the rover side, enabling dual-frequency RTK with no significant loss of accuracy. The technique is demonstrated for Galileo E5a/b and BeiDou B1C/B1I corrections.
