This section presents experimental results for navigation with cellular CDMA signals. These results did not suffer from the BTS sector clock discrepancy issue (discussed in Section 38.7), since signals from only one sector antenna in each BTS cell were used. Experimental results exhibiting the BTS sector clock discrepancy issue and mitigation approaches are studied in [23, 25]. Section 38.5.4.1 analyzes the pseudorange obtained by the receiver discussed in Section 38.5.2. Sections 38.5.4.2 and 38.5.4.3 present navigation results with aerial and ground vehicles, respectively.
