The following measurement processing parameters can be set for a GNSSReceiver object:
|TrackingID||The receiver ID. Must match the "Marker Number" for the associated RINEX Observation file.|
|NumberOfChannels||Used by the simulator to control the number of GNSS measurements generated at any measurement time. The NumberOfChannels is the number of satellites that can be tracked for each basic type of measurement statistics (i.e., CA, P1 and/or P2) with which the GNSSReceiver is set up. For example, if the GNSSReceiver is set up with CA, P1 and P2 measurement statistics, and NumberOfChannels is set to 8, then the simulator can simultaneously simulate CA, P1 and P2 measurements for 8 satellites.|
|MinGrazingAlt||The minimum grazing altitude for editing out GNSS measurements. (Available for Space type GNSSReceiver only.)|
The minimum SNR needed to accept a GNSS measurement for processing. Used only if the S1 parameter or SSI flags are output in the RINEX Observation file. If the SSI flags are output, ODTK maps the SSI flag value to SNR as follows:
Set the following attributes:
|MaxPhaseRangeGapTime||The maximum time allowed between accepted phase range measurements without reinitializing the initial range estimate. The initial range estimate is the range at the beginning of the contiguous count interval.|
Note: During simulation of GNSS measurements, if a GNSS satellite selection plugin is being used, but fails, the simulator will continue with a default selection which simply picks the first 4 satellites. When using a GNSS selection plugin to simulate measurements, check the message viewer carefully for plugin failure messages.
