The RANGE log contains the channel measurements for the currently tracked satellites. When using this log, please keep in mind the constraints noted along with the description.
It is important to ensure that the receiver clock has been set. This can be monitored by the bits in the Receiver Status field of the log header. Large jumps in pseudorange as well as Accumulated Doppler Range (ADR) occur as the clock is being adjusted. If the ADR measurement is being used in precise phase processing, it is important not to use the ADR if the "parity known" flag, in the ch-tr-status field, is not set as there may exist a half (1/2) cycle ambiguity on the measurement. The tracking error estimate of the pseudorange and carrier phase (ADR) is the thermal noise of the receiver tracking loops only. It does not account for possible multipath errors or atmospheric delays.
If multiple signals are being tracked for a given PRN, an entry for each signal, with the same PRN, appears in the RANGE logs. As shown in Table: Channel Tracking Status, these entries can be differentiated by bits 21-25, which indicate the signal type of the observation.
For dual antenna receivers, a RANGE_1 log can be requested to get RANGE data from the second antenna. As described in Table: Binary Message Header Structure, the message type indicates the log is from the second antenna. To request an ASCII log enter RANGEA_1, and for a binary log enter RANGEB_1.
